Microsoft Word, Excel, and PowerPoint already support the same OpenDocument format as LibreOffice and OpenOffice.
Microsoft is now testing OpenDocument Format 1.4 support, further improving compatibility between Office apps and third-party alternatives.
Microsoft Word, Excel, and PowerPoint now support OpenDocument Format 1.4 in the Beta Channel forMicrosoft 365 Insiders.
Excel can now save color filter controls to ODS files and has improved support for rotated text.
This is an important feature for screen readers and other assistive technologies.
ODF is also supported by the KDE Calligra suite, AbiWord, and other Office alternatives.
ODF 1.4 isstill a working draftand has not been fully standardized.
LibreOffice doesnt evenofficially support ityet, so Microsoft is actually ahead of the curve here.
That might cause minor compatibility issues with LibreOffice until it is fully updated.
