Office 2019 Convert File to Older Office File?

I would like to buy MS Office for study soon, as the university only supports MS Office and I do not, for example. Libre Office Portable is allowed to install.

Unfortunately, I do not know exactly which MS Office version is on the laptops of the university, so here is my question:

If I buy Office 2019, can I convert the file to Office 2016 or 2013? And if possible so that little problems with the presentation occur?

The laptops are running Windows 7 and therefore should not support Office 2019.

You certainly have the option to save your files in previous Office versions.

This should not be a problem

MS Office can also read and write older MS Office formats (see "Save As" dialog box).

By the way, LibreOffice can do that as well. Works very well now. Display differences only exist if you have not installed the fonts used in the document.

Libreoffice or OpenOffice can do that

Above all, the brand new version 6.3 of LibreOffice should have refilled here once again.

I do not have an MS Office program installed, but I use LibreOffice.
I can't imagine that your university prohibits you from installing LibreOffice. - What does this ban justify?

However, MS Office believes that PP representations can be better than Impress presentations, and that file exchanges may cause a different representation due to compatibility issues.

To your Win7 laptops:
Upgrade to Win10. - This upgrade is still free!
How to do this is shown here:

If you want the video to run too fast, right-click the gear icon and set the playback speed to 0.75.

An advice: For the upgrade connect the laptop via LAN to the Internet.

When you're done with it, nothing stands in the way of the MS Office 2019 installation.

I somehow can't understand why everyone is relying on this MS Office.

If they absolutely ask for it then they should kindly move out a much cheaper student version…

And when exporting to an older MS Office version, certain features of the more modern version are always lost. So, when creating these documents, one should be careful not to use anything up-to-date to directly avoid incompatibilities. (Basically, that's absolute nonsense!)

And LibreOffice is really a very good office and in many areas at least equal to the MS Office.

And the argument with the Win7 has January 2020 but also done. So already within the current winter semester.

Who then uses Win7 in online operation, is your own fault.

Another tip:

A very good middle ground between MS Office and LibreOffice would be the Softmaker Office Pro.

The Pro version contains the current Duden corrector. This spelling and grammar checker is superior to MS-Office's worlds.

Also exists a version for Linux, Mac and for Android. So you could work on an Android tablet and mobile.
