Where does SharePoint Online open's Office documents like word excel etc?

[shoab shah]

I know this sounds silly. However am not getting any article / post which explicitly says that 'SharePoint Online will open MS Office documents (word, excel, ppt) in Browser (Office Online)'.

Moreover looking at the Compare SharePoint Online options getting an impression that 'SharePoint Online Option 1' which doesn't include 'Office Applications' will download Office files to client computer.

Kindly confirm "Whether SharePoint Online will open's Office documents like word excel etc in Office Online i.e. in Browser or not?"

Thank you

Depends on how you configure it, which features are available and what the document type is. We do have a SharePoint space in this community, I suggest you post the question there.

I'm moving this question to the SharePoint space for better visibility.

yes, by default all SharePoint documents open in Office Online. You can override this should you choose at a library level.
