This tool supports standard CSV (comma-separated values) files, as well as files using semicolons or tabs as delimiters. You can also paste raw CSV text directly. The delimiter is auto-detected, but you can manually select it if needed.

Yes. All processing happens entirely in your browser. Your CSV data is never uploaded to any server. Once you close or refresh the page, the data is gone.
