CSV to TSV
Drop in a .csv file (or paste the data) and download a tab-separated `.tsv` file. The delimiter in the source is auto-detected by papaparse, and the output always uses real tab characters as separators — handy for pasting into spreadsheets that prefer TSV, or for tools that don't deal well with quoted commas. Conversion runs entirely in your browser.
