Convert a multi-sheet workbook to CSV
A workbook can hold dozens of tabs, but the CSV format has no idea of sheets. Each CSV is one table. The usual answer is one file per tab, and the tool is set up for that.
Your file is never uploaded. The converter runs in your browser and makes no network requests while it works.

Steps
- Load the workbook once. The Sheet menu fills with every tab name in the file.
- Select the first tab you need, glance at the preview and click Download.
- Pick the next tab from the menu. The preview updates without reloading the file, and your delimiter, date and BOM choices stay as they were.
- Repeat until you have every tab you need.
Good to know
File names
When a workbook has more than one sheet, the sheet name is added to the download name, for example report-Q3_Sales.csv. Spaces and symbols in the sheet name become underscores.
Keep settings consistent
If the files will be merged later, keep the same delimiter and date style for every tab so the columns line up.
Summary tabs
Tabs full of totals, charts or notes rarely make useful CSVs. Export the raw data tabs and rebuild summaries in the destination app.
Checking row counts
The status line under the drop box shows how many rows the selected sheet has, which is a quick way to confirm nothing went missing.
Questions
Can I download every sheet in one go?
Not yet. Pick each sheet and download it in turn. Your settings carry over between sheets.
Can I combine sheets into one CSV?
Not in this tool. Export each sheet, then stack them in your spreadsheet app if they share the same columns.
