Convert CSV to TSV for Unix tools and legacy importers

Turn comma-separated CSV exports into tab-separated TSV for shell pipelines, log tools, and importers that expect tabs with AnyConv365.

Updated 2026-07-15

Spreadsheets export CSV with commas. Many Unix tools, ETL jobs, and legacy importers still require tab-delimited TSV.

Quick steps

Open CSV to TSV.
Upload your .csv file.
Download the TSV and spot-check columns that contained commas inside quoted fields.

Tips

Need tabs back to commas? TSV to CSV flips delimiters the other way.
Heading to Excel formulas? CSV to XLSX builds a workbook instead.
Exporting from Excel later? XLSX to CSV gives flat data for scripts.

When CSV to TSV is the right call

Choose CSV→TSV when the next step is a tab-expecting pipeline — not when humans will open the file in Excel (which prefers CSV). Keep CSV for universal spreadsheet sharing.

Spreadsheet conversions may use AnyConv365 servers depending on file size; uploads are deleted after processing.
