TSV to CSV
Convert tab-separated text into CSV locally in your browser.
Paste TSV or choose a local tab-delimited text file to produce comma-separated values for spreadsheets, data imports, and systems that expect CSV. The conversion runs on your device, reports malformed quoted fields, and warns when rows do not share the same width.
Selecting a file replaces the pasted input. Files are read by this page on your device only.
How to use
Paste tab-separated values or load a local text file, choose the CSV delimiter your destination expects, then convert. Quoted TSV fields may contain tabs, doubled quote characters, and line breaks; those values are preserved and quoted when needed in the CSV output.
TSV and CSV are text table conventions rather than complete spreadsheet formats. The tool writes delimited text and does not evaluate formulas, apply cell types, or infer dates. It warns about uneven row widths so you can review data before importing it elsewhere.
Some spreadsheet apps may evaluate cells that begin with =, +, -, or @ after import. Review formula-looking values before opening CSV from untrusted sources in spreadsheet software.
Input and selected files stay in the browser. Very large files may be slow in one browser tab, and private data should only be opened on devices and pages you trust.
