Convert CSV to Excel
A CSV file is just plain text, so opening it directly in Excel often mangles leading zeros, long numbers, and dates. Converting CSV to a proper .xlsx workbook gives you a real spreadsheet with typed cells that you can sort, filter, and format. The whole conversion happens in your browser, with no upload.
Drop your .csv below and choose XLSX.

Frequently asked questions
Will my data be split into proper columns?+
Yes. The converter parses the comma delimiters and places each field in its own cell, so you get clean columns instead of everything crammed into column A.
Does converting to Excel add formulas or formatting?+
No. CSV holds only values, so the resulting workbook contains plain typed cells. You can add formulas, styles, and charts in Excel afterward.
What about semicolon-separated or tab-separated files?+
Standard CSV uses commas. If your file uses tabs, convert it as TSV instead; for semicolon files, re-save with comma delimiters first so the columns split correctly.
