Convert TSV to CSV — Free Online Converter, No Upload

Convert tab-separated to comma-separated — the universal spreadsheet and Excel format. The conversion runs entirely in your browser using JavaScript and the Canvas API — your file never leaves your device, no signup required, no watermarks added.

Why convert TSV to CSV?

CSV is the universal language of spreadsheets. Converting TSV to CSV ensures your file opens cleanly in Excel, Google Sheets, Numbers, and virtually every reporting and BI tool — and is the standard format for data sharing between systems.

Common use cases

• Open in Excel without import wizard
• Upload to Google Sheets
• Share with non-technical teammates
• Use with BI tools (Tableau, Power BI)

How to convert TSV to CSV

1. Drag your .tsv file into the converter, or click to browse.
2. Press the Convert to CSV button — your browser does all the work locally.
3. Download the resulting .csv file. Your original file was never uploaded anywhere.

Privacy

SafeRestore's TSV to CSV converter is 100% client-side. We never upload, log, or store your files. The whole conversion happens in the browser sandbox on your own device.
