How do you convince people to use open document format?

One of the biggest challenge I face while convincing people to switch to GNU/Linux is the compatibility issue of open document format with that of Microsoft format. We know that Libre Office is a complete office suit that we can use for any type of office work. Most of office work will be preparing documents, spreadsheets and presentations. Now, we can save these files in Microsoft office format say .docx, .xlsx etc. and we can also access and edit those documents created using Microsoft office word and excel. But the problem is sometimes we face formatting issue e.g what you're seeing in Libre office may not be same for Microsoft office especially when tables, images and charts are used. One major problem is with ppt which hardly matches to that of power point.

If I convince my colleagues to switch to GNU/Linux, they'll ask series of questions and I can answer most of them but major problem is with office suit. I have to say that you will need to use Microsoft power point for making ppts and sometimes you may need to use Microsoft Word when you find mis-matching.

I think the actual problem is using microsoft format and why we use that format (docx, xlsx, pptx)? Because others are using them. If we save documents in open document format then others will not be able to open/access them because they're using MS-Office. So, this problem is only going to be solved if all use open document format. (sometimes what happens: we may need to submit documents to our head who is using Ms-Office or sometimes we may need to mail them to another institutions whose people are using Ms-Office)

So, How do you convince people to use open document format?

I think if I can have solution to above mentioned problem, then there are high chances that I can convince my colleagues to switch to GNU/Linux.

Thanks .
