Working with XLSX to CSV

Each visible sheet becomes its own CSV. The first visible sheet is selected by default; choose another sheet or export all visible sheets for a ZIP download.

CSV stores formatted cell values, not workbook styling or formulas. Missing cached formula results stay empty. Hidden sheets are omitted.
