Key=value resource bundles used by Java, Spring Boot and Kotlin backends. Each language lives in its own messages_xx.properties file next to the default bundle.
It is used by Java, Spring Boot, Kotlin, Thymeleaf. SimpleLocalize reads and writes it natively, so you keep your existing project structure. Format value for the CLI and API: java-properties. Read the format documentation.

- Import your .properties 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.
