Is there a free JSON translator?

Yes. JSON Translate includes a free tier for smaller files and one output language.

What changes in paid plans?

Paid plans increase file size, character, and language limits. Pro also adds protected words and diff highlighting.

Developer JSON translation

Use the free tier for smaller JSON localization files, then upgrade only when you need larger files, more output languages, or protected words.

Free tier for quick JSON translation jobs

Upload, paste, translate, and download in one browser flow

Built for localization JSON rather than general document translation

Start with a valid JSON language file from your app or website.

Choose one free output language, or use paid plans for larger multilingual batches.

Keep the file structure intact so developers can test it quickly.
