About Converting Microsoft Office Documents

LibreOfficeDev can automatically open Microsoft Office 97/2000/XP documents. However, some layout features and formatting attributes in more complex Microsoft Office documents are handled differently in LibreOfficeDev or are unsupported. As a result, converted files require some degree of manual reformatting. The amount of reformatting that can be expected is proportional to the complexity of the structure and formatting of the source document. LibreOfficeDev cannot run Visual Basic Scripts, but can load them for you to analyze.

The most recent versions of LibreOfficeDev can load and save the Microsoft Office Open XML document formats with the extensions docx, xlsx, and pptx. The same versions can also run some Excel Visual Basic scripts, if you enable this feature at - Load/Save - VBA Properties.
