How to use this tool
CSV stores tabular data as plain text. This converter reads that data and places it into a new Excel XLSX workbook.
- Choose a CSV file.
- Select the delimiter used by the file: comma, semicolon, tab, or pipe.
- Review the preview and enter the worksheet name you want.
- Click Convert to XLSX and download the Excel workbook.
Delimiter selection
Choosing the correct delimiter is important because it tells the converter where each column begins and ends.
What gets created
The converter creates a new worksheet from the CSV rows and cells. Formatting that did not exist in the CSV cannot be recreated automatically.
Privacy and file handling
The CSV is read and converted in your browser.
