We have Office365. I need to import various Excel spreadsheets into SharePoint Online as lists. I have full administrator rights to SharePoint Online.
I have attempted to use the Import Spreadsheet app in all three browsers (Chrome, Edge, and Firefox). Every time I try to import the spreadsheet using this app, I get the following error message, and the spreadsheet won’t upload: "This feature requires
a browser that supports ActiveX controls." ActiveX controls are enabled on all three browsers. This doesn't seem to matter.
Then I tried opening the site in IE 11 and trying again to use Import Spreadsheet, which is what the “Help” dialog in SharePoint Online tells me to do, and I get this error: "This list cannot be imported because a Microsoft SharePoint Foundation-compatible
spreadsheet application is not installed or is not compatible with your browser." I am using the latest version of Excel, but I have saved my data as a.csv, an .xls file, on OneDrive, and finally, stripped any "complex" formulas out of it and tried uploading
it as plain data. I get the same error message each time, regardless of how I save or format my data. The "export to Excel" function on SharePoint Online works perfectly.
This should be a standard function of SharePoint Online, and should in no way be this difficult. This is a crucial activity, and I am extremely frustrated by how much time this has taken me so far.
Please tell me how I can upload my spreadsheets?
