CSV to Excel
CSV to Excel is a free online converter that turns CSV files into Excel (.xlsx) format. Upload several CSV files at once and choose to keep each as its own worksheet or merge everything into one sheet, with delimiter options including comma, semicolon, tab, pipe, and auto-detect.
Files are parsed and converted locally in your browser — nothing is uploaded, so business data stays private. Free with no sign-up, it's great for turning exported CSV data into Excel reports or consolidating multiple CSVs into a single workbook.
How to Use
- Click to upload or drop one or more .csv files
- Pick a delimiter or leave it on auto-detect
- For multiple files, choose a merge mode: separate sheets or one combined sheet
- Click convert and download the resulting Excel file
FAQ
Is the CSV to Excel converter free?
Yes, completely free with no limits on conversions or file count, and no account required.
Are my CSV files stored on a server?
No. Files are parsed and converted entirely in your browser, and the finished Excel file is downloaded locally — nothing is uploaded.
Can I convert multiple CSV files at once?
Yes. Upload several CSVs together and choose between two merge modes: each file becomes its own worksheet named after the file, or all rows are combined into a single sheet.
What if my CSV doesn't use commas?
The tool supports comma, semicolon, tab, and pipe delimiters, plus an auto-detect option that figures out the delimiter from the file content.
