When Should You Use XLSB vs POTM?

XLSB vs POTM: Key Differences

• •The core technical difference: XLSB relies on lossless compression whereas POTM uses lossless compression.
• •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
• •Alpha channel support: POTM handles transparency.
• •POTM files tend to be differently sized than XLSB
• •Primary audience: XLSB is built for large enterprise spreadsheets, financial modeling, big data analysis scenarios, while POTM focuses on interactive presentations, automated slide generation — pick the format that matches your output requirement.
