Export Excel workbook sheets as separate CSV files

An XLSX workbook may contain multiple sheets; CSV can represent one flat table only. Select the converter and CSV output to get one downloadable card for every nonempty worksheet. Up to 20 sheets are supported.

The first row of each sheet is displayed as the header. The output uses displayed cell values, with commas and UTF-8 encoding. Formatting, merged layouts, charts, comments, macros and workbook links are outside this conversion.

Formulas are not executed. A formula cell relies on the value last saved by the original spreadsheet application; without a cached value it can be blank. Recalculate and save your workbook in Excel or LibreOffice before exporting if current formula results matter.

Review every output separately, especially sheets with blank leading rows or complex layouts. The preview shows only the first 10 data rows and first 20 columns. Download each card separately and compare important totals with the original workbook.
