TSV to CSV Converter

Convert tab-separated values to CSV and back, preserving quoted fields.

Two-way conversion between TSV (tab-separated) and CSV (comma-separated). Quoted fields with commas, tabs or newlines are preserved correctly using RFC 4180 quoting. Useful for moving spreadsheet exports between tools that prefer different delimiters.

Common use cases

  • Convert tab-separated paste from Excel/Google Sheets into proper CSV
  • Translate database exports between TSV and CSV pipelines
  • Strip unwanted quoting introduced by a particular export tool
  • Re-emit data feeds using whichever delimiter your downstream tool expects

Frequently asked questions

Why convert between TSV and CSV?
Most spreadsheet tools paste as TSV but many APIs and import dialogs expect CSV. The converter handles edge-case quoting so you don't lose data.
Does it preserve unicode and emoji?
Yes — text is processed as Unicode strings end-to-end.
Will it auto-detect the input format?
Pick the direction explicitly. Auto-detection is in the dedicated CSV Formatter tool.
