Frequently Asked Questions
Why would I convert XLSX back to XLS?
Converting to XLS format is useful for compatibility with older Excel versions (Excel 97-2003) or legacy systems that don't support the newer XLSX format. However, XLS has limitations like fewer rows and larger file sizes.
Will I lose data when converting XLSX to XLS?
If your XLSX file has more than 65,536 rows or 256 columns, data will be truncated when converting to XLS format. Also, some newer Excel features may not be supported in the older XLS format.
