Localization Editor EX

🗂️ What is Localization Editor EX?

Localization Editor EX works directly on top of Unity's official Localization package. No migration, no new string table format, no changes to your existing project setup. You keep everything you already have and get a dramatically better editing experience on top of it.

✏️ Edit All Languages at Once

The default Unity string table editor forces you to jump between one table per locale. Localization Editor EX replaces only that editor window: all your locales appear side by side in a single expandable row per key. Click a key, edit every translation at once, and move on. A live search lets you filter by key name or source text. Missing translations are automatically flagged, so nothing slips through before a build.

📤 Professional Translator Workflow

When you work with professional translators, XLIFF 1.2 export gets your files out of Unity and straight into any CAT tool. Import works just as cleanly. Per-key context notes let you give translators the exact guidance they need without emails back and forth.

⚙️ Extra Features & Zero Overhead

Smart String support, full Undo/Redo via Unity's own Undo system, natural sort order (key_2 before key_10), and automatic dark/light theme support come included. There is no runtime component and no impact on build size.
