CSV to Excel
CSV to Excel packages a plain text file into a genuine .xlsx workbook that opens instantly in Excel, LibreOffice or Google Sheets with the columns already split correctly. It saves you from the import wizard every time, and gives colleagues a real spreadsheet instead of a text file they have to convert themselves.
How to use CSV to Excel
- Load your .csv file or paste the CSV text.
- Press Convert to build a workbook with one sheet and the header row intact.
- Check the column split — delimiters and quoted fields are handled automatically.
- Download the .xlsx file and open it in your spreadsheet app.
CSV to Excel FAQ
Will Excel open this without warnings?
Yes. The output is a real .xlsx workbook, not a renamed CSV, so Excel opens it directly.
Does it handle large files?
Large files are fine, though very big sheets are limited by how much your browser can hold in memory. Split unusually large exports first.
Can I convert more than one sheet?
The converter builds a single sheet from one CSV. Combine several outputs afterwards with Merge if you need a multi-sheet workbook.
