Frequently Asked Questions

How are Excel formulas handled?

You can choose to either preserve formulas in their original form or convert them to their calculated values. When preserving formulas, they are included as text content in the XML, making them visible and reusable in other contexts.

What about merged cells?

The converter can automatically expand merged cells, repeating their value across all affected cells. This ensures a consistent data structure in the XML output while preserving the information from the original spreadsheet.

How are dates handled?

Excel dates can be automatically converted to ISO 8601 format (YYYY-MM-DD) for standardized representation in the XML output. This ensures compatibility with XML processing tools and maintains data type accuracy.

Is my data secure?

Yes, all processing happens entirely in your browser. No data is sent to any server, ensuring your sensitive Excel data remains private and secure throughout the conversion process.
