Hi @southafrican ,
I'm afraid there's no way to directly save data from excel to sharepoint list in PowerApps currently.
However, I suggest you try to use collection as intermediate medium.
I've made a similar test for your reference:
1)connect your app with the excel file and sharepoint list
2)save data from excel to collection
Collect(collectionname,excel tablename)
3)save data from collection to sharepoint
In this step, fields' data type in sharepoint list is very important.
If you use complex data type, the formula should make a little change.
I assume that all your fields are text type.
Then try this formula:
ForAll(collectionname,Patch(listname,Defaults(listname),
{list fieldname1:collection fieldname1,
list fieldname2:collection fieldname2,
list fieldname3:collection fieldname3,....}
)
)
Please replace collctionname, listname, fieldname with the names that you want to use.
Here's a doc about how to update multiple records at the same time:

Here's a doc about how to update complex data type of sharepoint list:
(If you use complex data type in sharepoint, please refer this doc to modity my formula)
