Why "JSON translation" can be tricky at times
Translating a JSON file isn't the same as just translating text - it's preserving structure, placeholders, and formatting, as well as dealing with very short strings or even single word key value pairs that have very little context. We understand how much it means to get things right - JTranslate pluts accuracy as the priority, it's built into every stage of our translation pipeline - we don't settle for results that "look right", they need to be right.
Placeholder safety
Variables are protected and are grammatically correct in the target language.
Structure preservation
The resulting JSON keeps the original structure and key ordering as the source.
Production-ready output
Download locale files that are ready to go live.
