Frequently asked questions

My Excel file has several sheets: can I convert one?
Yes. Every sheet in the workbook is listed, and you pick exactly which one to export. CSV holds a single table, so you convert one sheet at a time, which keeps each output clean and predictable.
Which delimiter should I choose?
A comma is the default and works almost everywhere. Choose a semicolon if your data already contains commas or you will open the file in a region where Excel expects semicolons, and tab if a tool asks for TSV. The tool quotes any value that needs it, so commas inside a cell never break the columns.
Will dates and numbers stay correct?
Yes. Numbers are written as plain values and dates are written in a standard text form, so the CSV reads cleanly in spreadsheets, databases and scripts without the formatting quirks Excel sometimes adds.
Is my file sent to a server?
No. Everything runs locally in your browser. Your file is read and processed on your own device, nothing is uploaded, and nothing is logged or stored.
