About TSV and CSV

TSV is tab-separated values — spreadsheet data without the comma-escaping headaches. CSV is comma-separated values — the universal format for spreadsheets and data exchange. Moving data between the two by hand is slow and error-prone — this converter does it in one click, preserving the structure of your data.
