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.
