About this tool
Change the field delimiter in a TSV file — switch from comma to tab, pipe, semicolon, or any custom character. Fields containing the new delimiter are automatically quoted to keep the output valid.
Frequently Asked Questions
What delimiters can I switch to when changing the delimiter in a TSV file?
Comma, tab, pipe (|), semicolon, or any custom single character you type in.
What happens if my data values contain the new delimiter?
The tool automatically quotes any field that contains the chosen delimiter, following standard CSV quoting rules. Your data is safe.
Can I convert a TSV file to CSV using this tool?
Yes. Load a TSV file and choose comma as the output delimiter to produce a standard comma-separated CSV file.
Is my data private?
Yes — completely. Your file is never uploaded to any server. Everything runs locally in your browser using WebAssembly — processing happens entirely inside your tab. Once you close the tab, nothing is retained.
What is the maximum file size?
The free limit is 50 MB. For larger files, performance depends on your device's available memory — most modern machines handle 500 MB to 1 GB comfortably.
