CSV to Excel Converter
About the CSV to Excel Converter
The CSV to Excel Converter turns a plain CSV file into a proper .xlsx workbook, with columns detected automatically so the data lands in tidy cells. When you need the formatting, formulas, and familiarity of Excel, this upgrades raw CSV into a real spreadsheet.
CSV is great for portability but awkward to work with directly: no formatting, no formulas, and a wall of commas. Converting to Excel gives you a workbook you can sort, filter, chart, and format like any other spreadsheet.
Conversion happens in your browser, so your data never leaves your device. That keeps exports and records private, with automatic column detection and no upload or account needed.
How to use the CSV to Excel Converter
- Upload your CSV file or paste the CSV data.
- Confirm the delimiter so columns are detected correctly.
- Review the detected columns in the preview.
- Convert the data into an Excel workbook.
- Download the resulting .xlsx file.
Common use cases
- Turning a CSV export into a formatted, workable Excel sheet.
- Opening comma-separated data cleanly in columns rather than one cell.
- Preparing CSV data for sorting, filtering, and charting in Excel.
- Converting a database or app export into a spreadsheet for review.
Frequently asked questions
Will my columns be detected automatically?
Yes. The tool detects the delimiter and splits the data into proper columns, so it opens cleanly in Excel rather than crammed into a single column.
What if my CSV uses semicolons instead of commas?
You can set the delimiter to match your file, so semicolon- or tab-separated data is parsed into the correct columns.
Does it add formulas?
Conversion places your values into cells; you can then add formulas, sorting, and formatting in Excel as you would with any workbook.
Is my data uploaded anywhere?
No. The conversion runs in your browser, so your data never leaves your device.
How do I convert Excel back to CSV?
