A family of Microsoft word processing software products for creating web, email, and print documents.
Hi VickiCarter2,
I go through the post carefully. if you are using Chromebook with Chromebook OS, you may not install desktop version of Office 365 on your Chromebook just like if you use Windows.(for more information: How to install and run Microsoft Office on a Chromebook) Instead, you can install and use Office mobile app on your Chromebook.
However, it is not supported now to use customize fonts in Office mobile app now. as a workaround, you may edit document in Office 365 on pc, embed fonts to it(for more information: Embed fonts in Word or PowerPoint). so that you can see the fonts on you Chromebook. Additionally, I would suggest you vote for the thread in Word UserVoice: My idea is about fonts which will promote the related team of office mobile develop the feature.
Thanks for your understanding.
Best Regards,
Clark
