Frequently Asked Questions

Find Quick Answers

What file formats are supported?

This tool supports .xlsx Excel files. For older .xls files, please convert them to .xlsx format first using Microsoft Excel or other spreadsheet software.

Is there a file size limit?

The tool can handle files up to 50MB. For larger files, consider splitting them into smaller spreadsheets before conversion.

Does it preserve formatting and formulas?

CSV is a plain text format that only stores data values. Formulas, formatting, and macros from the original XLSX file will not be preserved in the CSV output.

What happens with multiple sheets?

By default, the converter processes the first sheet. You can select which sheet to convert from the preview area before conversion.

Is my data secure?

All file processing happens securely on our servers. Files are automatically deleted after conversion, and we don't store or share your data.
