Turn a CSV file into an Excel workbook
CSV is great for moving data but poor for working with it: no types, no formulas, no formatting. Converting CSV to XLSX gives the data a real spreadsheet home where you can sort, filter, add formulas, and share it with people who expect an Excel file.
This tool builds an XLSX workbook from a CSV file, locally in your browser. The workbook contains the CSV's values as data; it does not create formulas, multiple sheets, or styling — those are added in Excel afterwards. Success depends on the source CSV's structure, so unusual delimiters or quoting deserve a quick review first.

PRACTICAL TIPS
Before you start
- Check the CSV's delimiter (comma vs semicolon) if the columns look wrong after conversion.
- Leading zeros (in codes or IDs) can be reinterpreted by spreadsheet apps — verify those columns.
- After conversion, set column types in Excel before building formulas on the data.
FAQ / CSV-TO-XLSX
Frequently asked questions
Will column types be detected?
Values are carried as text-focused data; review number and date columns after conversion.
What about quoted commas?
Standard CSV quoting is parsed; unusual delimiters should be checked in the source first.
Is the CSV uploaded?
No. The conversion happens in your browser.
