TSV to CSV Converter
Turn tab-separated values into properly quoted CSV.
Tabs into commas, safely
Converting tab-separated data to CSV is not just swapping tabs for commas — any field that already contains a comma or quote must be escaped, or the CSV breaks. This tool does it properly.
It splits each line on tabs and rebuilds it as valid CSV, quoting and escaping fields as needed. Paste a spreadsheet export and get clean, correct CSV back.
Correct and private
The conversion runs in your browser, so your data is never uploaded.
