Tick Translate automatically after creating and choose a translator.

Import

Click Import file & create and choose a CSV, JSON, PO or XLIFF file.

Each language becomes its own project under Your Developer projects, with Open, Export and Re-import. Export writes the same format you imported.

If you have your game's project folder

Localize your own game reads your readable source files in three steps: choose the folder, pick the languages, and create the projects. It works on source folders only, and refuses a packed build.

The Localize your own game steps: choose a folder, pick the languages, create the projects.

These are normal game projects, so they appear on the Translation Projects page, and Export rebuilds the game.

Supported: RPG Maker MV, MZ, XP and VX, Ren'Py, Wolf RPG, TyranoScript, NScripter, Godot, Unity, Bakin, SRPG Studio and Electron. For other engines, export a PO or CSV file from the engine's own tool and use the strings file route.

Project slots

Each language takes one project slot. The whole batch is checked first, and if it would go over your limit, nothing is created.
