XLSX at a glance
XLSX
Convert to XLSX when recipients need an editable spreadsheet rather than a flat data export.
It is appropriate for financial models, reporting packs, planning templates, reconciliations, inventory sheets, and business deliverables where formulas, formatting, or multiple worksheets must survive.
Choose XLSX over CSV when workbook structure matters, and over PDF when users need to keep calculating, filtering, or annotating the data after delivery.
It is the practical target for spreadsheet collaboration inside office-centric organizations.

PPM
Convert to PPM when a technical workflow needs a simple RGB raster format for processing, benchmarking, or intermediate conversion.
