Suggested reviewers: Merge Risk: 🟡 Moderate · up to Schema imports can synchronously update many records in one request, but the current implementation has no explicit bounds on request size, operation count, duration, or concurrency, and concurrent imports may race when creating missing localized values. This could tie up application workers or database locks and cause import failures, so the change needs explicit owner acceptance or mitigation before merge. 🚥 Pre-merge checks | ✅ 3 | ❌ 3❌ Failed checks (3 warnings)

Full details: Linked Issues checkExplanation The PR implements the core JSON import workflow, validation, localization updates, backup warning, and error handling [ Resolution Add the required import-mode and language selection controls, implement or explicitly support both import modes, add successful completion notification, and provide the required user documentation for supported and unsupported configuration elements [ Full details: Out of Scope Changes checkExplanation The schema import changes are in scope, but formatting-only changes in ChooseCollection/index.tsx, Core/Main.tsx, Router/Routes.tsx, and WbToolkit/GeoLocate.tsx are unrelated to the linked schema import objective [ Full details: Testing InstructionsExplanation The testing instructions are not fully accurate for the implemented import flow. The checklist says to review changed tables and fields and then click Save, but Resolution Update the manual checklist to say: select the file, download the backup if required, click Continue Import, wait for the loading state to finish, and verify the reloaded schema. Remove the post-import Save instruction. Add explicit checks for the confirmation dialog, loading completion, invalid JSON/incompatible schema errors, missing formatter/pick-list/web-link handling, and read-only or permission-restricted users. Add or document an integration test that causes a failure during a multi-operation import and verifies rollback, and document how to run the backend and frontend tests.

language-checking logic to require alphabetic two-character language and
optional country tokens, rejecting punctuation such as "@@" and "en-$%". Add
regression cases covering these invalid values while preserving valid
language-only and language-country inputs.

isinstance(table_data, dict) check to raise ValueError when a known table’s
container exists but its table_data is not a dictionary; retain the current
continue behavior for unknown tables.

Importing a schema in another language should trigger some sort of warning message for the user. |

Everything passes except that I got an error when importing this json file. It took some minutes before it showed the error message. However it passes once I imported the export from another database.config/common/schema_localization_en.json

I was also able to see the invalid JSON rejection when uploading query export:

Normalize locale keys before the lookup.
_schema_import_string uses exact country matching. A countryless import can miss existing rows with country='', and an en-US import can miss rows with country='US'. The importer can then create duplicate Splocaleitemstr rows. Match the repository’s NULL/blank and lowercase locale forms, and add regression tests.

- Open Schema Config for a collection using a user that has schema-edit permissions.
- Confirm Export button (in top left) downloads the current full schema-localization JSON.
- Make changes to various fields in Schema Config and verify Import is disabled until it has been saved.
- Select Import and download the current schema backup when prompted.
- Select a full schema export from another database, or reset the schema by importing the
config/common/schema_localization_en.json. - Review the changed tables and fields, then click Save.
- Refresh Schema Config and confirm the imported captions and values remain.
- Try an invalid JSON file (export a query if you need one) and confirm the import is rejected without making any changes to the schema.
As suggested, I have pulled from multiple databases in testing this PR. For documentation purposes, those databases were KU Fish, OJMNH, and KU Entomology. I could transfer the KU Fish and Entomology schema configs just fine, but when I moved to the OJMNH database, I received errors that the json file was not supported. I originally thought this was due to the difference in collections, but the import still did not work.
The process of importing in general seems very slow, so perhaps adding some sort of loading bar or estimated time to completion could be a beneficial addition.

When checking the Developer Tools, I believe I found something that could be tied to why that it is loading long while importing, from the screenshots that I took. It seem to fail to send request and kept throwing a 421 error, the error might be on the API call you're making when importing the JSON file
Partially fixes #6155, as it is only the basic schema import/export mechanism.
Adds Schema Config import for full schema-localization JSON exports. Note that it can take over a minute to restore a schema as it performs a lot of updates to accomplish.

This is best tested by exporting various schema config files from different databases. Please test this with complex schemas that have custom pick lists and web links assigned, then import those exports into other databases missing those resources. Test exporting the current database and importing the export you just made while verifying the schema still has all the pick lists and captions assigned the same.
