Format JSON Translation Files
Validate and prettify i18n translation JSON files (en.json, de.json) used in React, Vue, and Next.js apps.
i18n tips
Translation files often grow to thousands of keys. Formatting with consistent 2-space indentation makes them readable and diff-friendly.
Missing closing brackets are hard to spot by eye. The JSON validator instantly shows the exact line and column of any syntax error.
Minify your translation JSON before shipping to production — smaller files mean faster initial page loads for your users.
Use tree view to navigate deeply nested translation key groups without scrolling through hundreds of flat keys.
