File formats
Investigating compatibility issues.
First we need to think about sharing presentations in a form that your colleagues can view and edit. So it’s good to note that LibreOffice Impress, Calligra Stage and Google Slides support the main presentation software formats of PPT, PPTX (PowerPoint) and ODP (OpenDocument), either as their native format or for import and/or export. However, in our experience, Stage isn’t as good as Impress at correctly interpreting a PowerPoint file.
