Free Online TSV to CSV Converter

Convert tab-separated data (TSV) to comma-separated format (CSV) instantly. Automatically handles quoting for fields with commas or special characters.

How the TSV to CSV Converter Works

This tool replaces tab characters with commas. Fields containing commas, double quotes, or newlines are automatically wrapped in double quotes following RFC 4180 standards.

When to Use TSV vs CSV

TSV is commonly exported by databases and spreadsheet applications. CSV is more widely supported for data interchange. Converting makes your data compatible with more applications.

Handling Special Characters

The converter properly handles commas in data, escaped double quotes, and newlines within fields. Empty fields are preserved. Data integrity is maintained throughout conversion.

Frequently Asked Questions

How does it handle fields with commas?
Fields containing commas are automatically wrapped in double quotes to prevent the comma from being interpreted as a delimiter.
What if my TSV has quoted fields?
Double quotes in values are escaped by doubling them according to CSV standards.
Can I convert CSV back to TSV?
This tool converts TSV to CSV only. Use the CSV to JSON tool and reformat as needed for the reverse.
Does it preserve empty rows?
Empty rows are skipped for clean output. Rows with empty fields (consecutive tabs) are preserved with empty values.
What is the maximum file size?
Processing is in-browser. Tens of thousands of rows work well on modern devices. For very large files, use a command-line tool.
