Example use cases

1

Importing Excel data into another system

Many databases and apps only accept CSV - convert an Excel export before importing it.

2

Sharing spreadsheet data in a plain-text format

Turn a workbook into CSV for version control, scripting, or lightweight sharing.

3

Feeding a sheet into a CSV-based tool

Convert to CSV first, then use it with the CSV Cleaner, Sorter, or Filter tools.

Frequently asked questions

Which Excel formats are supported?

Standard .xlsx and legacy .xls files, plus .xlsm and OpenDocument .ods spreadsheets.

What happens with a workbook that has multiple sheets?

Every sheet in the file is listed in the sheet dropdown; pick the one you want converted and the CSV updates automatically.

Are formulas converted to their values?

Yes - the calculated value shown in each cell is used, not the underlying formula text.

Is my file uploaded anywhere?

No. The file is read and converted entirely in your browser using JavaScript - nothing leaves your device.
