About
CSV to XLSX turns text tables into real Excel workbooks on your computer. The header row becomes bold, numeric cells are typed as actual numbers (so SUM works), and the delimiter is auto-detected — comma, semicolon or tab.
Free converts 5 files a day. Pro removes the limit and adds explicit delimiter choice. One key covers up to 3 Windows PCs.
