What is this tool?
This tool opens an Excel workbook in your browser and exports the sheet you choose as CSV.
It is useful when you want to isolate one worksheet from a larger file and move it into a simpler format for imports, automation, or review.
How it works
- Upload an Excel file.
- Choose the worksheet you want to convert and decide whether the first row contains headers.
- Generate the output and download that sheet in the target format.
Conversion settings
Worksheet selection
You can export exactly the worksheet you need without converting the rest of the workbook.
Headers
Choose whether the first row contains column names. This matters especially for JSON output.
CSV delimiter
Pick comma, semicolon, tab, or pipe depending on the system that will import the file next.
Common use cases
- Extracting one worksheet to share without sending the full workbook.
- Turning an Excel tab into data that is easier to import into another platform.
- Preparing workbook data for automation, integrations, or quick validation.
