What is a .PPSX file?
PPSX is a PowerPoint slideshow - the same zipped XML package as PPTX, set to open straight into the presentation.
- Did you know
- PPSX is PowerPoint’s show-only format, which arrived with Office 2007’s XML files.
- Double-clicking a PPSX launches the slideshow directly with no PowerPoint editing interface visible.
- A PPSX is the same zipped XML package as a PPTX, with only a flag telling PowerPoint to open it in the slideshow rather than the editor.
- Under the hood a .PPSX file is really a ZIP archive - rename it to .zip and you can browse the files inside.
- What Analyser shows you
- Open and read Microsoft Office documents - modern Word, Excel and PowerPoint (DOCX, XLSX, PPTX), their template, macro-enabled and slideshow variants (DOTX, XLTX, POTX, DOCM, XLSM, PPTM, PPSX), the binary Excel workbook (XLSB), and the legacy 97-2003 binaries (DOC, XLS, PPT) - plus the OpenDocument family in every shape: zipped and flat single-XML text, spreadsheets, presentations and graphics (ODT, ODS, ODP, ODG, FODT, FODS), templates (OTT, OTS, OTP, OTG), legacy StarOffice (SXW, SXC, SXD), and EPUB e-books, shown as page previews with selectable text, tables, sheets and slides. Excel workbooks (XLSX and its macro/template variants, plus the binary XLSB) and OpenDocument spreadsheets (ODS) additionally open in a full analysis workbench alongside the sheet preview - a virtualised grid with sort, filter, search and column tools, a group-by summary, and a chart builder - to explore the data itself, not just preview it.
- Open a .PPSX file
- Drag a .PPSX file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
