About TSV to CSV
Use the TSV to CSV converter when a spreadsheet or import needs comma-separated data. It can convert tab separated values to CSV using a real table parser, so commas inside cells are quoted instead of mistaken for new columns.
How to convert TSV text into CSV
- Paste TSV text or import a .tsv file.
- Review spreadsheet formula-cell protection and select Process.
- Check the CSV and download it or continue to a column or deduplication tool.
A practical example
- Input
name note Ada red, blue
- Result
name,note Ada,"red, blue"
The comma belongs to the note cell, so the CSV writer surrounds that cell with quotes.
Supported input and limitations
- Input is limited to 5 MB, 100,000 records, 1,000 columns, and 1,000,000 cells. Blank records are skipped, and output uses CRLF record separators.
- This is text conversion, not XLSX import. Rows are not required to have equal widths; header-dependent next steps do require a regular table. Formula protection can prefix risky cells with an apostrophe.
Processing happens on your device. Read about local processing and optional workspace recovery.
Frequently asked questions
Does TSV to CSV preserve the header row?
Yes. The first row is retained as parsed data. No new header is invented and no original header is removed.
Can TSV fields contain quoted tabs or newlines?
Properly quoted fields are parsed by Papa Parse. Malformed quotes produce an error instead of a successful result.
