CSV to Excel (XLSX) converter
Make an Excel workbook from a CSV. Each row becomes a row, and plain numbers become numeric cells.
How it works
The CSV is parsed and written as a one-sheet XLSX file, built on this device with the same OOXML format Excel uses.
Cells that look like numbers but would lose precision, such as 007, stay as text.
Your files stay on this device. Nothing is uploaded, and the converter runs entirely in your browser.
Questions
Does the file open in Excel?
Yes. It is a standard XLSX workbook with one sheet named Sheet1.
Are formulas or formatting kept?
The CSV holds only values, so the workbook has values and no formatting.
Are my files uploaded?
No. Every conversion runs in your browser, on this device. Files are not sent to PartPriced Tools or to any other server.
