CSV to Excel converter
Need a real Excel workbook from a CSV export? Upload your .csv file and download .xlsx in seconds. Free with fair-use limits — we do not save your file or run cleanup.
Supports .csv
Free conversion · file not saved · no cleaning credits · 20 conversions per hour.
How conversion works
- Upload a comma-separated CSV file.
- We parse rows and headers in memory — nothing is stored on our servers.
- You get an Excel workbook (.xlsx) download immediately.
- Need duplicates or dates fixed? Use the full spreadsheet cleaner afterward.
When to convert vs clean
- Converting CSV to XLSX does not remove duplicates or fix bad dates.
- Opening CSV in Excel and Save As can break encoding — our converter keeps UTF-8 text intact.
- Very wide CSV files should be checked after download — column count is preserved.
- For CRM import, run cleanup after conversion to dedupe and normalize phones.
