Why convert XLSB to XML?
XLSB stores worksheet data as binary BIFF12 records inside a ZIP package. The XML Spreadsheet 2003 target (SpreadsheetML) was introduced in Excel 2002 and abandoned when .xlsx arrived in Excel 2007; it cannot represent pivot tables, charts, or conditional formatting from modern Excel, and no current tool or pipeline accepts it.

- XML Spreadsheet 2003 cannot represent modern Excel features such as pivot tables, charts, or structured references - content using these is silently lost.
- XLSX is already the XML form of an Excel workbook; saving as
.xlsxis the complete answer if an XML-based format is the goal. - Renaming an
.xlsbfile to.xmlproduces an unreadable file - XLSB starts with ZIP magic bytes, not an XML declaration.
