CSV to Excel
Convert a CSV file into an Excel spreadsheet — free and processed entirely in your browser.
About CSV to Excel
A CSV file opens fine in Excel, but it isn't a real .xlsx workbook — no formatting, no multiple sheets, nothing Excel-specific. This tool converts your CSV data into a genuine Excel (.xlsx) file.
Choose your delimiter and whether the first row is a header, matching the options already familiar from our XLSX to CSV tool. Everything runs locally in your browser.
How to Convert CSV to Excel
Step 1
Upload your CSV file
Drag and drop a .csv file, or choose one from your device.
Step 2
Set your options
Choose your delimiter and whether to treat the first row as a header.
Step 3
Download your Excel file
Save the result as a .xlsx file, ready to open in Excel.
Frequently Asked Questions
Will my CSV's formatting or formulas carry over?
A CSV file is plain text with no formatting or formulas to begin with, so there's nothing to lose — you get a clean spreadsheet with your data in properly separated columns.
What delimiters are supported?
Comma, semicolon, tab, and pipe — the same options available in our XLSX to CSV tool, so both directions handle the same range of CSV variants.
Can I convert a CSV with a different delimiter than a comma?
Yes — select the correct delimiter your CSV actually uses before converting.
Is my file uploaded anywhere?
No. Conversion happens entirely in your browser.
