• •Moving from PPSX (lossy) to XLSX (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
• •Alpha channel support: XLSX lacks transparency support, so semi-transparent pixels from the source will be lost.
• •XLSX files tend to be differently sized than PPSX
• •Use case fit: PPSX targets slide presentations, kiosk displays, automated demos and XLSX targets spreadsheets, data analysis, calculations — your choice depends on which workflow stage you are serving.
