What is OTH?

OTH (OpenDocument HTML Template) combines OpenDocument features with HTML compatibility for creating web-ready documents and online forms in LibreOffice.

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.

When Should You Use OTH vs XLSB?

OTH vs XLSB: Key Differences

• •OTH and XLSB diverge on compression: lossless compression for the source, lossless compression for the target.
• •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
• •How transparency is handled: XLSB supports transparency, so alpha information is preserved during conversion.
• •File sizes: OTH files typically range 10KB to 500KB for typical templates and XLSB files 30-50% smaller than XLSX for equivalent data.
• •OTH is optimized for web document templates, html-based forms, online publishing while XLSB is designed for large enterprise spreadsheets, financial modeling, big data analysis — choose based on your specific workflow needs
