CSV to Excel Converter - Frequently Asked Questions
What is the difference between CSV and Excel?
CSV is a plain text format with comma-separated values, while Excel (.xlsx) is a spreadsheet format that also stores formatting, multiple sheets and formulas.
Is my data uploaded when I convert?
No. The conversion happens entirely in your browser, so spreadsheets with sensitive data never leave your device.
Will my columns and rows be preserved?
Yes. The first CSV row becomes the header row and every following row is written as a row in the Excel sheet, with quotes and commas handled correctly.
Which delimiters are supported?
Comma-separated files are supported out of the box, including quoted fields that contain commas, newlines or double quotes.
Is the CSV to Excel converter free?
Yes, it is free to use with no file limits, no watermark and no account required.
