What it does
Upload an Excel workbook. See all the sheets it contains. Select the ones you want — download each as a clean CSV, individually or as a zip.
The problem it solves
Multi-sheet workbooks are common for monthly reports, department summaries, and data exports from accounting software. Extracting a single sheet requires opening Excel, right-clicking, and going through a save-as flow. For 5 sheets you need that 5 times. This does it in one pass.
What it handles automatically
- Sheet listing — Shows all sheet names and row counts before you commit
- Date and number format preservation — Converts Excel date serials and formatted numbers to readable values
- Empty sheet filtering — Skips sheets with no data by default
- ZIP download — Select multiple sheets and download them all at once as a zip archive
FAQ
What about password-protected workbooks? Password-protected workbooks are not supported. Remove the protection in Excel first.
Are formulas preserved? CSV doesn't support formulas — the tool exports the calculated values, not the formulas.
Does it store my data? No. Processing is in your browser. The workbook never leaves your machine.
