Tab-separated data from a sheet or a database export needs to become CSV for tools that expect commas.
This converter splits your rows on tabs and writes CSV, automatically quoting any field that contains a comma so the columns stay correct.
How to use TSV to CSV
- Paste your tab-separated text into the left panel.
- The tool parses the tabs and converts to CSV live.
- Copy the CSV from the right panel or download it as a CSV file.
What you can do with it
- Convert a sheet export from TSV to CSV.
- Turn database rows into comma-separated values.
- Prepare tab-separated logs for a CSV importer.
Good to know
CSV serialization must quote any cell that contains a comma, a quote or a newline, otherwise the columns break. This tool applies that quoting as it builds each comma-separated row.
Frequently asked questions
What happens to cells with commas?
They are wrapped in double quotes in the CSV output, so the comma stays inside the field instead of splitting it.
Are empty cells preserved?
Yes. Empty tab-separated fields become empty CSV fields, keeping the column structure.
Does it handle quotes in cells?
Yes. Existing double quotes are doubled inside a quoted field, the standard CSV escaping.
