FAQ
Common questions about the CSV to Excel Converter
How do I convert a CSV file to Excel?
Upload or paste your CSV into the Wansify CSV to Excel Converter, check the preview, and click Convert to Excel. An .xlsx file downloads that opens directly in Microsoft Excel, Google Sheets or LibreOffice.
Can I convert an Excel file back to CSV?
Yes. Switch to Excel → CSV, upload a .xlsx, .xls or .ods file, pick a sheet, and download it as CSV or copy it. You can also choose a semicolon, tab or pipe separator.
Does it work with semicolon-separated or tab-separated files?
Yes. The converter detects comma, semicolon, tab and pipe delimiters from the first line automatically.
Why do long numbers or leading zeros change when I open a CSV in Excel?
Excel stores only 15 significant digits and drops leading zeros from numbers. This converter keeps values like phone numbers, card numbers, IDs and codes such as 007 as text so they are not changed.
Is my CSV file uploaded to a server?
No. The tool runs entirely in your browser, so nothing you enter or upload is sent to a Wansify server.
Is the CSV to Excel converter free?
Yes. It is free to use with no sign-up.
