### What?
Improves both the JSON preview and export functionality in the
import-export plugin:
- Preserves proper nesting of object and array fields (e.g., groups,
tabs, arrays)
- Excludes any fields explicitly marked as `disabled` via
`custom.plugin-import-export`
- Ensures downloaded files use proper JSON formatting when `format` is
`json` (no CSV-style flattening)
### Why?
Previously:
- The JSON preview flattened all fields to a single level and included
disabled fields.
- Exported files with `format: json` were still CSV-style data encoded
as `.json`, rather than real JSON.
### How?
- Refactored `/preview-data` JSON handling to preserve original document
shape.
- Applied `removeDisabledFields` to clean nested fields using
dot-notation paths.
- Updated `createExport` to skip `flattenObject` for JSON formats, using
a nested JSON filter instead.
- Fixed streaming and buffered export paths to output valid JSON arrays
when `format` is `json`.
### What?
Replaces all `payload.logger.info` calls with `payload.logger.debug` in
the `createExport` function.
### Why?
info logs are too verbose. Using debug ensures detailed logs.
### How?
- Updated all logger calls in `createExport` to use `debug` instead of
`info`.
### What?
Fixes the `custom.plugin-import-export.disabled` flag to correctly
disable fields in all nested structures including:
- Groups
- Arrays
- Tabs
- Blocks
Previously, only top-level fields or direct children were respected.
This update ensures nested paths (e.g. `group.array.field1`,
`blocks.hero.title`, etc.) are matched and filtered from exports.
### Why?
- Updated regex logic in both `createExport` and Preview components to
recursively support:
- Indexed array fields (e.g. `array_0_field1`)
- Block fields with slugs (e.g. `blocks_0_hero_title`)
- Nested field accessors with correct part-by-part expansion
### How?
To allow users to disable entire field groups or deeply nested fields in
structured layouts.
### What?
Fixes the export field selection dropdown to correctly differentiate
between fields in named and unnamed tabs.
### Why?
Previously, when a `tabs` field contained both named and unnamed tabs,
subfields with the same `name` would appear as duplicates in the
dropdown (e.g. `Tab To CSV`, `Tab To CSV`). Additionally, selecting a
field from a named tab would incorrectly map it to the unnamed version
due to shared labels and missing path prefixes.
### How?
- Updated the `reduceFields` utility to manually construct the field
path and label using the tab’s `name` if present.
- Ensured unnamed tabs treat subfields as top-level and skip prefixing
altogether.
- Adjusted label prefix logic to show `Named Tab > Field Name` when
appropriate.

/>
### What?
Adds support for excluding specific fields from the import-export plugin
using a custom field config.
### Why?
Some fields should not be included in exports or previews. This feature
allows users to flag those fields directly in the field config.
### How?
- Introduced a `plugin-import-export.disabled: true` custom field
property.
- Automatically collects and stores disabled field accessors in
`collection.admin.custom['plugin-import-export'].disabledFields`.
- Excludes these fields from the export field selector, preview table,
and final export output (CSV/JSON).
### What?
Adds a new `format` option to the `plugin-import-export` config that
allows users to force the export format (`csv` or `json`) and hide the
format dropdown from the export UI.
### Why?
In some use cases, allowing the user to select between CSV and JSON is
unnecessary or undesirable. This new option allows plugin consumers to
lock the format and simplify the export interface.
### How?
- Added a `format?: 'csv' | 'json'` field to `ImportExportPluginConfig`.
- When defined, the `format` field in the export UI is:
- Hidden via `admin.condition`
- Pre-filled via `defaultValue`
- Updated `getFields` to accept the plugin config and apply logic
accordingly.
### Example
```ts
importExportPlugin({
format: 'json',
})
### What?
Adds support for two new plugin options in the import-export plugin:
- `disableSave`: disables the "Save" button in the export UI view.
- `disableDownload`: disables the "Download" button in the export UI
view.
### Why?
This allows implementers to control user access to export actions based
on context or feature requirements. For example, some use cases may want
to preview an export without saving it, or disable downloads entirely.
### How?
- Injected `disableSave` and `disableDownload` into `admin.custom` for
the `exports` collection.
- Updated the `ExportSaveButton` component to conditionally render each
button based on the injected flags.
- Defaults to `false` if the values are not explicitly set in
`pluginConfig`.
### Example
```ts
importExportPlugin({
disableSave: true, // Defaults to false
disableDownload: true, // Defaults to false
})
### What?
Updated the `FieldsToExport` component to use the current list view
query (`query.columns`) instead of saved preferences to determine which
fields to export.
### Why?
Previously, the export field selection was based on collection
preferences, which are only updated on page reload. This caused stale or
incorrect field sets to be exported if the user changed visible columns
without refreshing.
### How?
- Replaced `getPreference` usage with `useListQuery` to access
`query.columns`
- Filtered out excluded fields (those prefixed with `-`) to get only the
visible columns
- Fallbacks to `defaultColumns` if `query.columns` is not available
### What?
Added a delayed toast message to indicate when an export is being
processed, and disabled the download button unless the export form has
been modified.
### Why?
Previously, there was no feedback during longer export operations, which
could confuse users if the request took time to complete. Also, the
download button was always enabled, even when the form had not been
modified — which could lead to unnecessary exports.
### How?
- Introduced a 200ms delay before showing a "Your export is being
processed..." toast
- Automatically dismisses the toast once the download completes or fails
- Hooked into `useFormModified` to:
- Track whether the export form has been changed
- Disable the download button when the form is unmodified
- Reset the modified state after triggering a download
### What?
Improves the flattening logic used in the import-export plugin to
correctly handle polymorphic relationships (both `hasOne` and `hasMany`)
when generating CSV columns.
### Why?
Previously, `hasMany` polymorphic relationships would flatten their full
`value` object recursively, resulting in unwanted keys like `createdAt`,
`title`, `email`, etc. This change ensures that only the `id` and
`relationTo` fields are included, matching how `hasOne` polymorphic
fields already behave.
### How?
- Updated `flattenObject` to special-case `hasMany` polymorphic
relationships and extract only `relationTo` and `id` per index.
- Refined `getFlattenedFieldKeys` to return correct column keys for
polymorphic fields:
- `hasMany polymorphic → name_0_relationTo`, `name_0_id`
- `hasOne polymorphic → name_relationTo`, `name_id`
- `monomorphic → name` or `name_0`
- **Added try/catch blocks** around `toCSVFunctions` calls in
`flattenObject`, with descriptive error messages including the column
path and input value. This improves debuggability if a custom `toCSV`
function throws.
### What?
Updated the `selectionToUse` export field to properly render a radio
group with dynamic options based on current selection state and applied
filters.
- Fixed an edge case where `currentFilters` would appear as an option
even when the `where` clause was empty (e.g. `{ or: [] }`).
### Why?
Previously, the `selectionToUse` field displayed all options (current
selection, current filters, all documents) regardless of context. This
caused confusion when only one of them was applicable.
### How?
- Added a custom field component that dynamically computes available
options based on:
- Current filters from `useListQuery`
- Selection state from `useSelection`
- Injected the dynamic `field` prop into `RadioGroupField` to enable
rendering.
- Ensured the `where` field updates automatically in sync with the
selected radio.
- Added `isWhereEmpty` utility to avoid showing `currentFilters` when
`query.where` contains no meaningful conditions (e.g. `{ or: [] }`).
### What?
Fixes a sync issue between the "Fields to Export" `<ReactSelect />`
dropdown and the underlying form state in the import-export plugin.
### Why?
Previously, the dropdown displayed outdated selections until an extra
click occurred. This was caused by an unnecessary `useState`
(`displayedValue`) that fell out of sync with the `useField` form value.
### How?
- Removed the separate `displayedValue` state
- Derived the selected values directly from the form field value using
inline mapping
### What?
Fixes an issue where only the fields from the first batch of documents
were used to generate CSV column headers during streaming exports.
### Why?
Previously, columns were determined during the first streaming batch. If
a field appeared only in later documents, it was omitted from the CSV
entirely — leading to incomplete exports when fields were sparsely
populated across the dataset.
### How?
- Adds a **pre-scan step** before streaming begins to collect all column
keys across all pages
- Uses this superset of keys to define the final CSV header
- Ensures every row is padded to match the full column set
This matches the behavior of non-streamed exports and guarantees that
the streamed CSV output includes all relevant fields, regardless of when
they appear in pagination.
### What?
Ensure the export preview table includes all field keys as columns, even
if those fields are not populated in any of the returned documents.
### Why?
Previously, if none of the documents in the preview result had a value
for a given field, that column would be missing entirely from the
preview table.
### How?
- Introduced a `getFlattenedFieldKeys` utility that recursively extracts
all missing flattened field accessors from the collection’s config that
are undefined
- Updates the preview UI logic to build columns from all flattened keys,
not just the first document
This PR consists of two separate changes. One change cannot pass CI
without the other, so both are included in this single PR.
## CI - ensure types are generated
Our website template is currently failing to build due to a type error.
This error was introduced by a change in our generated types.
Our CI did not catch this issue because it wasn't generating types /
import map before attempting to build the templates. This PR updates the
CI to generate types first.
It also updates some CI step names for improved clarity.
## Fix: type error
This fixes the type error by ensuring we consistently use the _same_
generated `TypedUser` object within payload, instead of `BaseUser`.
Previously, we sometimes used the generated-types user and sometimes the
base user, which was causing type conflicts depending on what the
generated user type was.
It also deprecates the `User` type (which was essentially just
`BaseUser`), as consumers should use `TypedUser` instead. `TypedUser`
will automatically fall back to `BaseUser` if no generated types exists,
but will accept passing it a generated-types User.
Without this change, additional properties added to the user via
generated-types may cause the user object to not be accepted by
functions that only accept a `User` instead of a `TypedUser`, which is
what failed here.
## Templates: re-generate templates to update generated types

Needed for #12860.
The new live preview pattern requires collection-level preferences, a
pattern that does not yet exist.
Instead of creating a new record for these types of preferences, we can
simply reuse `<collectionSlug>-list` under a more general key:
`collection-<slug>`. This way other relevant properties can be attached
in the future that might not specifically apply to the list view.
This will also match the conventions already estalished by
document-level preferences in `collection-<slug>-<id>` and
`global-<slug>`.

### What
This PR updates the import-export plugin's `<Preview />` component to
render table columns and rows using the same logic as the CSV export.
Key changes:
- Adds a new `/api/preview-data` custom REST endpoint that:
- Accepts filters (`fields`, `where`, `sort`, `draft`, `limit`)
- Uses `getCustomFieldFunctions` and `flattenObject` to transform
documents
- Returns deeply flattened rows identical to the CSV export
- Refactors the <Preview /> component to:
- POST preview config to the new endpoint instead of querying the
collection directly
- Match column ordering and flattening logic with the `createExport`
function
- Ensures consistency across CSV downloads and in-admin previews
-Adds JSON preview
This ensures preview results now exactly match exported CSV content,
including support for custom field transformers and polymorphic fields.

This PR fixes an issue in the export logic where CSV downloads would
include duplicate rows and repeated column headers across paginated
batches.
Key changes:
- Ensured `page` is incremented correctly after each `payload.find` call
- Tracked and wrote CSV column headers only once for the first page
- Prevented row duplication by removing unused `result` initialization
and using isolated `page` tracking
- Streamlined both download and non-download logic for consistent batch
processing
This resolves incorrect row counts and header duplication in large CSV
exports.
### What?
Fixes CSV export support for polymorphic relationship and upload fields.
### Why?
Polymorphic fields in Payload use a `{ relationTo, value }` structure.
The previous implementation incorrectly accessed `.id` directly on the
top-level object, which caused issues depending on query depth or data
shape. This led to missing or invalid values in exported CSVs.
### How?
- Updated getCustomFieldFunctions to safely access relationTo and
value.id from polymorphic fields
- Ensured `hasMany` polymorphic fields export each related ID and
relationTo as separate CSV columns
### What?
Ensure fields using a custom `toCSV` function that return `undefined`
are excluded from the exported CSV.
### Why?
Previously, when a `toCSV` function returned `undefined`, the field key
would still be added to the export row. This caused the column to appear
in the CSV output with an empty string value (`""`), leading to
unexpected results and failed assertions in tests expecting the field to
be truly omitted.
### How?
Updated the `flattenObject` utility to:
- Check if the value returned by a `toCSV` function is `undefined`
- Only assign the value to the export row if it is explicitly defined
- Applied this logic in all relevant paths (arrays, objects, primitives)
This change ensures that fields are only included in the CSV when a
meaningful value is returned.
The custom save button showing on export enabled collections in the edit
view. Instead it was meant to only appear in the export collection. This
makes it so it only appears in the export drawer.
Type declaration extending `custom.['plugin-import-export']` was
incorrectly named `toCSVFunction` instead of `toCSV`. This changes the
type to match the correct property name `toCSV`.
When making an export of a collection, and no fields are selected then
you get am empty CSV. The intended behavior is that all data is exported
by default.
This fixes the issue that from the admin UI, when the fields selector
the resulting CSV has no columns.
### What?
In a project that has `jobs` configured and the import/export plugin
will error on start:
`payload-jobs validation failed: taskSlug: createCollectionExport is not
a valid enum value for path taskSlug.`
### Why?
The plugin was not properly extending the jobs configuration.
### How?
Properly extend existing config.jobs to add the `createCollectionExport`
task.
Fixes #
This makes it possible to add custom logic into how we map the document
data into the CSV data on a field-by-field basis.
- Allow custom data transformation to be added to
`custom.['plugin-import-export'].toCSV inside the field config
- Add type declaration to FieldCustom to improve types
- Export with `depth: 1`
Example:
```ts
{
name: 'customRelationship',
type: 'relationship',
relationTo: 'users',
custom: {
'plugin-import-export': {
toCSV: ({ value, columnName, row, siblingDoc, doc }) => {
row[`${columnName}_id`] = value.id
row[`${columnName}_email`] = value.email
},
},
},
},
```
The i18n namespace `movingFromFolder`'s second dynamic variable name
should be `{{fromFolder}}`, but lots of locales use `{{folderName}}`, so
it will fail to get the value.
8199a7d32a/packages/ui/src/elements/FolderView/Drawers/MoveToFolder/index.tsx (L360-L363)
There is also some optimization for Folder related translation and
generic terms of zh.ts included inside.
Converts all text and field labels into variables that can be
translated. Also generated the translations for them
So now the UI here is internationalised
I've also moved some of the generic labels into the core package since
those could be re-used elsewhere
I think it's easier to review this PR commit by commit, so I'll explain
it this way:
## Commits
1. [parallelize eslint script (still showing logs results in
serial)](c9ac49c12d):
Previously, `--concurrency 1` was added to the script to make the logs
more readable. However, turborepo has an option specifically for these
use cases: `--log-order=grouped` runs the tasks in parallel but outputs
them serially. As a result, the lint script is now significantly faster.
2. [run pnpm
lint:fix](9c128c276a)
The auto-fix was run, which resolved some eslint errors that were
slipped in due to the use of `no-verify`. Most of these were
`perfectionist` fixes (property ordering) and the removal of unnecessary
assertions. Starting with this PR, this won't happen again in the
future, as we'll be verifying the linter in every PR across the entire
codebase (see commit 7).
3. [fix eslint non-autofixable
errors](700f412a33)
All manual errors have been resolved except for the configuration errors
addressed in commit 5. Most were React compiler violations, which have
been disabled and commented out "TODO" for now. There's also an unused
`use no memo` and a couple of `require` errors.
4. [move react-compiler linter to eslint-config
package](4f7cb4d63a)
To simplify the eslint configuration. My concern was that there would be
a performance regression when used in non-react related packages, but
none was experienced. This is probably because it only runs on .tsx
files.
5. [remove redundant eslint config files and fix
allowDefaultProject](a94347995a)
The main feature introduced by `typescript-eslint` v8 was
`projectService`, which automatically searches each file for the closest
`tsconfig`, greatly simplifying configuration in monorepos
([source](https://typescript-eslint.io/blog/announcing-typescript-eslint-v8#project-service)).
Once I moved `projectService` to `packages/eslint-config`, all the other
configuration files could be easily removed.
I confirmed that pnpm lint still works on individual packages.
The other important change was that the pending eslint errors from
commits 2 and 3 were resolved. That is, some files were giving the
error: "[File] was not found by the project service. Consider either
including it in the tsconfig.json or including it in
allowDefaultProject." Below I copy the explanatory comment I left in the
code:
```ts
// This is necessary because `tsconfig.base.json` defines `"rootDir": "${configDir}/src"`,
// And the following files aren't in src because they aren't transpiled.
// This is typescript-eslint's way of adding files that aren't included in tsconfig.
// See: https://typescript-eslint.io/troubleshooting/typed-linting/#i-get-errors-telling-me--was-not-found-by-the-project-service-consider-either-including-it-in-the-tsconfigjson-or-including-it-in-allowdefaultproject
// The best practice is to have a tsconfig.json that covers ALL files and is used for
// typechecking (with noEmit), and a `tsconfig.build.json` that is used for the build
// (or alternatively, swc, tsup or tsdown). That's what we should ideally do, in which case
// this hardcoded list wouldn't be necessary. Note that these files don't currently go
// through ts, only through eslint.
```
6. [Differentiate errors from warnings in VScode ESLint
Rules](5914d2f48d)
There's no reason to do that. If an eslint rule isn't an error, it
should be disabled or converted to a warning.
7. [Disable skip lint, and lint over the entire repo now that it's
faster](e4b28f1360)
The GitHub action linted only the files that had changed in the PR.
While this seems like a good idea, once exceptions were introduced with
[skip lint], they opened the door to propagating more and more errors.
Often, the linter was skipped, not because someone introduced new
errors, but because they were trying to avoid those that had already
crept in, sometimes accidentally introducing new ones.
On the other hand, `pnpm lint` now runs in parallel (commit 1), so it's
not that slow. Additionally, it runs in parallel with other GitHub
actions like e2e tests, which take much longer, so it can't represent a
bottleneck in CI.
8. [fix lint in next
package](4506595f91)
Small fix missing from commit 5
9. [Merge remote-tracking branch 'origin/main' into
fix-eslint](563d4909c1)
10. [add again eslint.config.js in payload
package](78f6ffcae7)
The comment in the code explains it. Basically, after the merge from
main, the payload package runs out of memory when linting, probably
because it grew in recent PRs. That package will sooner or later
collapse for our tooling, so we may have to split it. It's already too
big.
## Future Actions
- Resolve React compiler violations, as mentioned in commit 3.
- Decouple the `tsconfig` used for typechecking and build across the
entire monorepo (as explained in point 5) to ensure ts coverage even for
files that aren't transpiled (such as scripts).
- Remove the few remaining `eslint.config.js`. I had to leave the
`richtext-lexical` and `next` ones for now. They could be moved to the
root config and scoped to their packages, as we do for example with
`templates/vercel-postgres/**`. However, I couldn't get it to work, I
don't know why.
- Make eslint in the test folder usable. Not only are we not linting
`test` in CI, but now the `pnpm eslint .` command is so large that my
computer freezes. If each suite were its own package, this would be
solved, and dynamic codegen + git hooks to modify tsconfig.base.json
wouldn't be necessary
([related](https://github.com/payloadcms/payload/pull/11984)).
### What?
The order of fields, when specified for the create export function was
not used for constructing the data. Now the fields order will be used.
### Why?
This is important to building CSV data for consumption in other systems.
### How?
Adds logic to handle ordering the field values assigned to the export
data prior to building the CSV.
