Some of these differences result from the licensing change for Apache OpenOffice, and the restriction that Apache projects observe concerning code under incompatible licenses. Other differences arise as the result of variations in features of the application and especially functions such as conversions to and from other formats, provision of authoring tools (spell checkers, etc.), internationalization, macros, Java dependencies and so on, features that are not subject to the ODF specification. Both projects have participants who are also on the OASIS ODF TC. Improvements and fixes in this area will likely remain synchronized, as will any common security vulnerability repairs. In that respect, the coverage of the ODF feature sets are comparable.

Finally, he PPTX import/export filter has been improved.With regard to ODF support, there is substantial common code. A long time Office XLSS bug, the 'invalid content error' when opening exported XLSX files with shapes has also been resolved.

The program can also now export to XLSX files with sheet names longer than 31 characters and exporting XLSX checkboxes. This greatly improves interoperability across multiple MS Office versions. LibreOffice 7's DOCX is now saved in native 2013/2016/2019 mode, instead of 2007 compatibility mode. At the top of the list for users who've spent their working lives with Microsoft Office, the best feature is better compatibility with DOCX, XLSX, and PPTX files. This new major release comes with several improvements. Oh, and did I mention? LibreOffice won't cost you a cent. But, if you want an old-style office suite which lives on your PC, LibreOffice is now your top choice. Maybe paying an eternal subscription fee for Microsoft works for you. As a 'last resort' - Microsoft's words, not mine - Microsoft recommends Office 2019. Microsoft has made it clear that it sees the desktop office suite future on the cloud, not on your PC.
