How to use CSV to Excel
- Upload a comma-separated CSV.
- Convert the rows into one worksheet.
- Download the XLSX workbook.
Good to know
- Comma delimiter only. Values are stored as text to preserve leading zeros and avoid running formulas. Maximum 100,000 rows.
Check the output before using it. Complex formatting, fonts, or embedded objects may differ from your original.
A few helpful answers.
Will leading zeros survive?
Yes. CSV values are written as text, so identifiers such as 00123 remain intact. You can change column types in Excel after downloading.
