Developer JSON translation
A JSON translator built for developers
General translation tools are built for prose. JSON Translate is built for locale files that need to keep working after translation.
Keeps app-owned keys and structure unchanged
Works with common frontend i18n JSON formats
Pairs translation with validation through the free CLI
A safer JSON translation flow
1
Start from the source locale
Use the source JSON file your app already loads successfully as the canonical structure.
2
Translate only user-facing values
Keep keys, nesting, arrays, variables, and technical tokens stable while generating translated copy.
3
Validate before merge
Run @json-translate/check against translated files to catch missing keys and placeholder drift.
