BabelEdit
A localization editor for JSON, YAML, CSV, PO, XLIFF, and popular framework formats, with key trees, plurals, placeholder checks, search, and machine-translation integrations.
Why use it
Translators can edit structured resources without uploading the whole project to a localization SaaS, exposing missing keys, damaged variables, and incomplete language coverage earlier.
Where it fits
Use art, animation, audio, levels, and narrative to make the game easy to read and its world convincing.
What to check
Licenses are managed by major version and seat, with a limited update period after purchase; machine translation sends text to the selected provider, so review data terms first.
