WORKFLOW

Import, edit, export.

Supports JSON objects up to 10 MB per file.
Export one JSON file, one language, or the project as a ZIP.

01

Import JSON files

Create a project, then import one or more JSON files for each language. File names become namespaces, such as common.json.

02

Edit string values

Edit translations side by side. Search keys and values, filter by namespace, or show missing and complete translations. Add a language from a blank template or without files. Only strings are editable; other JSON values are preserved.

03

Export your files

Download an individual JSON file, all files for one language, or the full project as a ZIP archive.

DATA AND LIMITS

Projects stay
in this browser.

Projects and edits are saved to browser storage on this device. The app does not upload files or use a translation service. There is no account or cross-device sync.

Saved in IndexedDB No server uploads

This app edits strings; it does not write translations for you. Browser data can be cleared, and edits across multiple tabs are not merged. Export backups regularly.
