Capabilities

## What JSON Translation does

### Keys never change

Only values are translated. Structure, nesting, and key names come back byte-identical.

### Interpolation safe

Variables, ICU plurals, and templating tokens are protected so runtime formatting keeps working.

### Repo-ready output

You get a valid JSON file per locale that can be committed without post-processing.

### Consistent with everything else

Shares translation memory with your website, app, and documentation, so the product speaks one vocabulary.

How it works

## Four steps, one orchestrated run

Every stage runs on the same platform, so nothing is exported, re-uploaded, or handed between tools.

- 01

### Upload the locale file

Your source-language JSON, however deeply nested.
- 02

### Pick target locales

Select every language you ship in.
- 03

### Translate values

Keys and tokens are held constant while values are translated with memory reuse.
- 04

### Commit

Download a file per locale and push it.

Who it is for

## Teams using JSON Translation

### Web app i18n

react-i18next, vue-i18n, and similar locale bundles.

### Mobile resources

JSON-backed strings in React Native projects.

### Config and content files

Structured content that lives in the repo.

### Continuous delivery

Translate new keys on every release.

FAQ

## Questions people ask

Are my keys or nesting changed?
+

No. Only string values are translated. Key names, ordering, and nesting are preserved so the file is a drop-in replacement.

What about interpolation variables and plurals?
+

Placeholders, ICU plural forms, and templating tokens are protected during translation so runtime formatting continues to work in every locale.
