XML resource files used by .NET, ASP.NET Core, Blazor, MAUI and WPF. Each data element holds a name, a value and an optional comment for translators.
It is used by .NET, ASP.NET Core, Blazor, MAUI, WPF. SimpleLocalize reads and writes it natively, so you keep your existing project structure. Format value for the CLI and API: resx. Read the format documentation.
How to translate .NET RESX files
- Create a free account and a project. The Community plan covers small apps with no credit card.
- Import your .resx file in the web editor, or push it from the terminal with the CLI.
- Add target languages and run auto-translation. Use DeepL or Google Translate for speed, or OpenAI, Claude and Gemini with your own API key for context-aware translations.
- Review in the editor with QA checks, glossary and screenshots, then download the RESX files or publish them to the translation hosting CDN.
Sync RESX files from CI
Add a simplelocalize.yml to the repository and run simplelocalize upload and simplelocalize download in your pipeline or GitHub Action:
# simplelocalize.yml
apiKey: YOUR_PROJECT_API_KEY
uploadFormat: resx
uploadPath: ./locales/{lang}.resx
downloadFormat: resx
downloadPath: ./locales/{lang}.resx
# simplelocalize.yml
apiKey: YOUR_PROJECT_API_KEY
uploadFormat: resx
uploadPath: ./locales/{lang}.resx
downloadFormat: resx
downloadPath: ./locales/{lang}.resxConvert RESX to other formats
The same project can export translations in more than 30 formats, and the free online converter works without an account:
