TSV to CSV — convert tab-separated data to comma-separated

A TSV to CSV converter transforms tab-separated values into comma-separated values, the universal format for spreadsheets, databases, and data exchange. FormatList's free online TSV to CSV converter handles quoted fields, embedded delimiters, and special characters automatically.

TSV files are common in database exports, scientific data, and logs. CSV is the most widely supported format for data exchange between applications. This tool bridges the gap with smart field quoting — fields containing commas or double quotes are automatically wrapped in quotes per CSV standards.

Common use cases

  • Database exports — convert TSV database dumps to CSV for spreadsheet analysis.
  • Data migration — transform TSV data for tools that only accept CSV.
  • ETL pipelines — normalize data formats during extract-transform-load workflows.
  • Log analysis — convert tab-separated log files to CSV for analysis.
  • Scientific data — prepare tab-separated research data for publication.

TSV to CSV FAQ

How does the TSV to CSV converter work?

It parses tab-separated values (TSV), handling quoted fields and escaped characters, then outputs comma-separated values (CSV) with proper field quoting. Fields containing commas, double quotes, or newlines are automatically wrapped in quotes.

What's the difference between TSV and CSV?

TSV (Tab-Separated Values) uses tabs to separate fields. CSV (Comma-Separated Values) uses commas. TSV is less common but often used in database exports, while CSV is the universal standard for spreadsheet and data exchange.

Does it handle quoted fields?

Yes. Fields wrapped in double quotes in the TSV input are preserved correctly, including tabs within quoted fields. Fields containing commas or double quotes in the output are automatically quoted per CSV standards.

Can I convert large TSV files?

Yes. The tool runs entirely in your browser and handles files up to your browser's memory limit. For very large files, consider splitting them first.

Is my data sent to a server?

No. All conversion happens locally in your browser. Your data never leaves your computer.
