Translate JSON values, keep the structure.
Upload a .json file to localize app strings and content. GLOTX translates the string values only — keys, nesting, numbers, and booleans are preserved. Upload, pick a language, and download — the layout, fonts, and structure come back exactly as they went in.

Frequently asked questions
Are my keys translated?
No. Only string values are translated; object keys, arrays, numbers, and booleans stay exactly as they are.
Is the structure preserved?
Yes. The nesting and shape of your JSON are kept identical — just the text values change.
Is this good for app localization?
Yes — it's ideal for turning one locale's strings file into another language while keeping the schema.
Translate more than JSON.
PDF, Word, Excel, PowerPoint, and JSON — all with the formatting preserved.
