How to use this tool
Paste your CSV data into the text box, or click “Upload .csv” to load a file from your device. A preview table appears automatically showing how your data will look.
Toggle “First row is a header” if your CSV includes column names, and they will appear in bold in the spreadsheet. When you are ready, click “Download Excel (.xlsx)” to save a properly formatted spreadsheet file.
This is useful for turning exported CSV data from another tool into a spreadsheet you can open directly in Excel, Google Sheets, or Numbers, with numbers and text typed correctly.
FAQ
- How do I convert a CSV file to Excel?
- Paste your CSV data into the box, or click 'Upload .csv' to load a file. Check the preview table, then click 'Download Excel (.xlsx)' to save it as a spreadsheet.
- Does it detect numbers automatically?
- Yes. Cells that look like plain numbers are written as numeric values in the spreadsheet, so they sort and calculate correctly in Excel, while text stays as text.
- What does 'First row is a header' do?
- When checked, the first row is treated as column headers and rendered in bold in the generated spreadsheet.
- Is my CSV data uploaded to a server?
- No. The CSV is parsed and converted to an .xlsx file entirely in your browser. Nothing is uploaded anywhere.
