An alternative solution would be to use Power Query/Get and Transform
Here is the MCode that will do what you want and export to Excel. You can then upload or link to your Access DB
Code:
let
Source = Excel.CurrentWorkbook(){[Name="Table3"]}[Content],
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Store", type text}, {"Location", type text}, {"Desktop", Int64.Type}, {"Tablet", Int64.Type}, {"Phone", Int64.Type}}),
#"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Changed Type", {"Store", "Location"}, "Attribute", "Value")
in
#"Unpivoted Other Columns"
