What is the difference between a TSV and a CSV file?

TSV (Tab-Separated Values) uses a tab character (\t) as the delimiter between columns, while CSV (Comma-Separated Values) uses a comma. TSV files are common exports from databases, bioinformatics tools, and some analytics platforms. Most spreadsheet applications prefer CSV.

How do I convert a TSV file to CSV format online for free?

Upload your .tsv or .txt tab-delimited file above. The converter replaces every tab delimiter with a comma, correctly handles quoted fields, and produces a standard UTF-8 CSV file you can open in Excel, Google Sheets, or any data tool.

Does the TSV to CSV converter correctly handle quoted fields and embedded commas?

Yes. If a field in the TSV contains a comma, the converter wraps it in double quotes in the CSV output, following the RFC 4180 standard. Fields that already contain quotes are escaped with a doubled-quote ("" ) as required.

Can I open the output CSV in Excel or Google Sheets directly?

Yes. The output is a standard UTF-8 encoded CSV file. Excel opens it via File → Open, and Google Sheets accepts it via File → Import. The column structure and data from the original TSV are preserved exactly.

Is the TSV to CSV converter free and private?

Free, no account needed, and fully private. Your file is never uploaded anywhere — conversion runs in your browser.
