IMPLEMENTATION
Viewers responsible for this format
XLSB stores modern Excel workbook records in the binary BIFF12 format rather than worksheet XML. Anyfile uses SheetJS to expose supported cells and sheets without converting or uploading the workbook.
Common question
Is XLSB just a renamed XLSX?
No. Both are modern Excel formats, but XLSB encodes workbook records in binary structures instead of XML parts.
