Frequently Asked Questions

Why convert Excel to CSV?+

CSV is the universal import format — databases, CRMs, e-commerce platforms, mailing tools and scripts all accept it, while .xlsx often isn't supported.

What happens to formulas and formatting?+

CSV is plain text: formulas become their calculated values and formatting (colors, fonts, merged cells) is dropped. Only the data survives — that's the point.

Which worksheet is converted?+

The first sheet in the workbook. If you need another sheet, move it to the first position before converting.

Is the output UTF-8?+

Yes — special characters are written as UTF-8, the encoding expected by modern tools and databases.
