Capabilities
What JSON Translation does
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.

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.
