Convert TSV to CSV
About This Tool
The TSV to CSV Converter transforms tab-separated values (TSV) files into comma-separated values (CSV) format. While both formats store tabular data, CSV is more widely supported by spreadsheet applications and databases.
Paste your TSV data or upload a file, and get properly formatted CSV output. Handles special characters, quotes, and large datasets.

Formula
Conversion Process
TSV uses tab characters to separate fields. CSV uses commas. Fields containing commas are automatically enclosed in quotes. Existing quotes in data are escaped (doubled) per RFC 4180 standard.
Examples
Examples
Example 1: Simple Data
TSV: Product[TAB]Price[TAB]Stock / Apple[TAB]1.50[TAB]100
CSV: Product,Price,Stock / Apple,1.50,100
Example 2: Data with Commas
TSV: Name[TAB]Address / John[TAB]123 Main St, Apt 4
CSV: Name,Address / John,"123 Main St, Apt 4"
Frequently Asked Questions
How do I convert TSV to CSV?
Paste tab-separated data or upload a .tsv file. The converter replaces tabs with commas and properly handles values containing commas (wrapping them in quotes). The output is a standard RFC 4180 CSV file.
What is the difference between TSV and CSV?
TSV uses tabs as delimiters, CSV uses commas. TSV is simpler because tabs rarely appear in data, so quoting is seldom needed. CSV is more widely supported by applications. Both store tabular data as plain text.
How are special characters handled during conversion?
Values containing commas, double quotes, or newlines are automatically wrapped in double quotes in the CSV output. Double quotes within values are escaped as "". Tab characters in the original data are treated as column separators.
Can I convert CSV back to TSV?
Yes. The tool works in both directions. Paste CSV data and select TSV output. It properly handles quoted CSV fields, removing quotes and converting commas back to tabs.
What applications use TSV format?
TSV is common in bioinformatics (gene expression data), linguistics (corpus data), spreadsheet exports, and database dumps. Excel and Google Sheets can export as TSV. Many command-line tools output tab-separated data by default.
