Make data from excel sheet available - webview of excel online

I’m trying to use data from an existing excel sheet in an app.
The excel sheet is a bit complex so I don’t want to rebuild it with ionic.

I tried to open the excel online share-link within a webview. It works so far, but I just can see the values, but there is no opportunity of playing around with the values. If I create a link that allows to edit the file everyone who is using the app is able to edit the original file and download the hole file. Both things that I don’t really want.

Have someone an idea how I can make my excel sheet available with ionic (in any way)?

Thanks a lot!

What did you end up doing/using?
