How to convert .pub files to .doc or .pdf

[EveryMom]

I could really use some help.  I need to convert a .pub file to something else, and I don't want a 'trial version' of Office 365 or some other silliness.
It's for my mother.  She has business cards that need to be updated and printed.
Any clues?  Or am I going to have to generate something on Open Office just to get this done?

LibeOffice might have ability to do this... see here: https://ask.libreoffice.org/en/question/14/can-i-use-microsoft-publisher-files-with-libreoffice/

And it's 100% compatible with any Office app...
