How to use this tool

Suitable use cases
Use this tool for quick developer tasks, documentation, debugging, migrations, content preparation, or local file checks where the input and output format are clear. It is not a replacement for a full production parser, editor, or deployment validation pipeline.
Output format
The result is CSV data text or a browser-generated download, depending on the tool. Keep the original input and verify the output in the application that will consume it.
Privacy
Content is processed in the browser by the page. The tool does not require an upload to a conversion server. Do not paste secrets, personal data, or files you are not authorized to handle on a shared device.
Important: browser parsers cover common practical cases. Always review generated files before using them in production, especially for configuration, subtitles, images and security-sensitive data.
