War Thunder Localization Editor
A lightweight GUI for editing your War Thunder .csv localization files. Fuzzy search, fast edits with full undo history, profiles to save/apply changes, and handy utilities for refreshing the /lang folder or launching the game.
Technically, you can compile for MacOS and Linux using electron, but for now, only Windows is officially supported with an installer. I am very busy, however I will fix some of the UI clashes in the coming weeks to try to release a working cross platform build.
Features
CSV localization editor
Open any file in /lang, filter by key or value, and edit in place with an elegant UI.

How it works
1. Point to your root
Select your War Thunder root. The app uses its
/lang directory.
2. Search & edit
Filter by key/value and edit strings. The editor tracks your changes.
3. Save a profile
Make a snapshot of all edits. Keep multiple profiles for different setups.
4. Reapply after updates
When WT updates, refresh /lang and apply your profile in one click.
FAQ
Where do the CSV files live?
Inside your War Thunder root under /lang. NeoWT reads and writes those CSVs directly.
Does this work with Steam?
Yep. NeoWT can launch via Steam by default, or use the native launcher if you prefer.
Is macOS/Linux supported?
Unofficially. The UI works, but we don’t currently ship installers or test on those platforms.
Where are my profiles stored?
Profiles live locally next to NeoWT’s app data. They’re simple JSON snapshots of your edits.
