About
XLSX to CSV exports Excel workbooks to CSV on your computer. The first sheet is exported by default; numbers keep their values, dates come out ISO-formatted, and the output is UTF-8 with BOM so other tools read Cyrillic correctly.
Free converts 5 files a day (first sheet). Pro removes the limit and lets you export any sheet by name. One key covers up to 3 Windows PCs.
