What Excel formats does this tool support?

The tool supports both traditional XLS (Excel 97-2003) and modern XLSX (Excel 2007+) file formats.

Does the converter preserve formulas from my Excel file?

Formulas are converted to their calculated values in CSV and JSON outputs. PDF output preserves the visual representation of formulas as they appear in Excel.

What happens to multiple sheets in my Excel file?

For CSV output, you can choose to convert a specific sheet or all sheets (which creates separate CSV files). PDF output includes all sheets in a single PDF document. JSON output combines data from all sheets into a structured format.
