What is XLSB?

XLSB (Excel Binary Workbook) stores spreadsheet data in a binary format rather than XML, offering faster load and save times for large, complex workbooks while preserving all formulas and formatting.

What is DOC?

DOC is the legacy binary document format used by Microsoft Word 97-2003. While widely supported, it lacks some modern features found in DOCX.

When Should You Use XLSB vs DOC?

XLSB vs DOC: Key Differences

• •XLSB and DOC diverge on compression: lossless compression for the source, lossy compression for the target.
• •Moving from XLSB (lossy) to DOC (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
• •How transparency is handled: DOC does not support alpha channels — transparent areas in the source will become opaque.
• •File sizes: XLSB files typically range 30-50% smaller than XLSX for equivalent data and DOC files 50KB to 5MB.
• •Use case fit: XLSB targets large enterprise spreadsheets, financial modeling, big data analysis and DOC targets legacy documents, older systems — your choice depends on which workflow stage you are serving.
