What is CSV to TSV Converter?

CSV (comma-separated values) and TSV (tab-separated values) are the two most common plain-text formats for tabular data. CSV uses a comma (or semicolon) to separate fields; TSV uses a tab character. Many tools accept one format but not the other — databases, spreadsheet apps, and command-line tools often prefer TSV because tabs are unlikely to appear in data values, eliminating the need for quoting.

This converter parses your CSV — including quoted fields with embedded commas — and outputs clean TSV that can be pasted directly into spreadsheets, imported into databases, or processed with command-line tools like awk, cut, and sort.

How to Use CSV to TSV Converter

1

Paste CSV into the input area or click "Load Sample"

2

Select the input delimiter (or leave on Auto-Detect)

3

The TSV output updates instantly

4

Copy the TSV output or download it as a .tsv file

Common Use Cases

  • Data engineers converting CSV exports for import into tools that expect tab-delimited input.
  • Analysts pasting TSV directly into Google Sheets or Excel without quoting issues.
  • Developers converting CSV API responses to TSV for command-line processing with awk or cut.
  • Database administrators preparing data files for LOAD DATA commands that use tab delimiters.
  • Scientists converting CSV experiment data to TSV for bioinformatics pipelines.
  • Testers converting CSV test fixtures to TSV format expected by a test framework.

Example Input and Output

A CSV file with quoted fields containing commas is converted to clean tab-separated TSV.

CSV input
name,city,role
Alice,"New York, NY",Engineer
Bob,"Los Angeles, CA",Designer
Carol,"Chicago, IL",Manager
TSV output
name	city	role
Alice	New York, NY	Engineer
Bob	Los Angeles, CA	Designer
Carol	Chicago, IL	Manager

Privacy

All conversion runs in your browser. No data is uploaded to any server.

TSV in spreadsheets

When you copy TSV text and paste it into Google Sheets or Microsoft Excel, the application automatically splits the columns at tab characters — no import wizard needed.

Frequently Asked Questions

What is TSV?
TSV stands for Tab-Separated Values. It is a plain-text format where fields in each row are separated by a tab character (\t) and rows are separated by newlines. It is simpler than CSV because tabs rarely appear in data, so quoting is almost never needed.
How are quoted fields handled?
CSV fields that are wrapped in double quotes (e.g. "New York, NY") are parsed correctly — the quotes are removed and the field content is included without the surrounding commas causing a split. The output TSV does not use quoting.
What if my CSV uses semicolons instead of commas?
Select "Semicolon" as the input delimiter, or leave it on Auto-Detect and the tool will detect semicolons automatically based on your data.
What happens to tab characters inside field values?
If a CSV field value contains a tab character, it is replaced with four spaces in the TSV output to avoid breaking the column structure. This is rare in practice.
Is my data sent to a server?
No. All conversion runs in your browser. Your data never leaves your device.
