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.
