INPUT AND OUTPUT
Create a workbook from the data actually stored in CSV
The output creates a Data worksheet with a bold header row and readable column widths. CSV cell values are carried into the workbook as text, which helps preserve identifiers such as 001.
CSV does not contain workbook styles, multiple sheets, charts or an Excel formula model to reconstruct. Converting its extension does not recover those features; check and format the new workbook as needed.
FAQ
Common questions
Are my files uploaded?+
No. This tool processes files in browser memory on your device.
Is the tool free?+
Yes. Core processing is free, requires no account, and adds no watermark.
Will CSV-to-XLSX recover an original workbook’s formatting?+
No. A CSV contains tabular values, not the original workbook’s formatting, charts or separate sheets. The converter creates a new Data worksheet.
Are CSV values automatically typed as Excel numbers?+
The CSV parser keeps values as text. Review and convert numeric or date columns in your spreadsheet application when that is required.
