{ } How to use

  1. Paste your CSV.
  2. Select Process, then download the .xlsx file.

{ } How it works

CSV to Excel works on the text you provide. Select Process ▸ and it runs entirely in your browser — nothing is uploaded to a server — then shows the result in the Output panel.

Input

  • CSV input — paste or type your input in the left panel (use Sample for an example)

Output

A downloadable .xlsx workbook — use the Download button in the Output panel.

{ } Common uses

  • Give a colleague a real spreadsheet instead of a CSV they have to import.
  • Avoid the import dialog and the encoding questions CSV brings.
  • Turn an export into a workbook for a report.

{ } Limitations

  • Values are type-guessed on the way in: something that looks like a number becomes a number and something that looks like a date may become a date. A product code with leading zeros can lose them.
  • One sheet, no formatting and no formulas. Excel’s 32,767-character cell limit applies, and a longer value is truncated with a note.
  • The CSV is parsed by the spreadsheet library rather than by the site’s own CSV reader, so a very unusual quoting style may be read differently here than in CSV to JSON.

{ } FAQ

Is my data uploaded to a server?

No. Everything runs locally in your browser — your files never leave your device.

Can I process more than one file at once?

This tool works on one input at a time.

Is this tool free?

Yes — it’s completely free and needs no sign-up.

How do I stop it turning my codes into numbers?

You cannot from here — the type guessing is not configurable. If leading zeros matter, keep the CSV, or import it in Excel yourself and set the column to Text.
