CSV, TSV, or JSON

What it does

  • Open UTF-8 CSV/TSV files or paste delimited text.
  • Trim spaces, fill blanks, and remove duplicate or blank rows.
  • Edit cells, reorder columns, and undo recent changes.
  • Export CSV, TSV, or JSON with a preview.

A typical use

Remove duplicate contacts, tidy spacing in names, and export a clean CSV for your next tool.

Know the limits

  • Up to 5 MB per file, 5,000 data rows, 50 columns, and 100,000 cells including headers; additional text limits apply.
  • Values stay as text. JSON export needs unique, non-empty column names.
  • No native XLSX import. Working data is kept in the current tab, so export before leaving.
