VSTO Add in for Office 365

Question

I have a couple of Excel Add ins. If I move to Office 365, will these add ins be available ? Is there any development support(VSTO) for Office 365 ?

Answer 1

If you mean Office 365 installed on client PC then there is no issue with VSTO Add-ins. Our Chem4Word Add-in is using Office 2010 VSTO and happily works with 2010, 2013, 2016, 2019, O365.

If you mean Office 365 on-line then you have to redesign them using the Office 365 Javascript API
