Spreadsheets & data

Convert Excel to CSV Online — Free

Extract a clean CSV from your spreadsheet — comma-separated, UTF-8, first sheet only. Perfect for importing into databases, scripts, and other data tools.

  • No signup to try
  • Sandboxed processing
  • Files deleted in 24 h

What this does

  • First sheet only (sign in for multi-sheet export)
  • UTF-8 encoded, RFC 4180 compliant
  • Formulas evaluated to their result values

How it works

  1. 1

    Upload your XLSX

    Drop it above, or click to pick from your device. We validate the format immediately — no spinning on a file we can't process.

  2. 2

    Run the conversion

    The recipe runs in an isolated cloud sandbox — same as every other ReFile job. No AI guessing involved; it's a hand-written command that does one thing.

  3. 3

    Download the CSV

    Result lands in seconds. Files auto-delete from our servers after 24 hours; signed download URLs expire in the same window.

Frequently asked

What if I have multiple sheets?
Only the first sheet is exported by default. Sign in and ask in the chat for per-sheet CSV exports.
Do formulas become CSV columns?
Yes — the calculated value is written. The original formula is not preserved (CSV has no formula concept).
