Please tell me all file formats that are not supported by Office add-ins (Word, Excel, Power Point).

From Office365 (Excel, Word, PowerPoint) add-in, create an Office add-in that saves the file being edited by our SaaS.

Depending on the file format, there may be a phenomenon that the add-in is invalid and unavailable.

I have consulted about this question before, and Microsoft replied that the commonly used formats are basically supported, but after confirming that the doc format, xls format, and ppt format should not support add-ons, open the files of these three formats, and the add-in column is grayed out. unavailable state. So please check again.
