Not sure what your exact requirement is but below is one of the suggestions that can be used if you want to have the excel data in the clipboard (not uploading the excel data at runtime) :
- Create a Data Type with the properties that you want to be populated with the excel.
- Import the data from the excel (you will get the option to map the properties with the columns in excel while importing).
- Once you have created a Data Page and imported the data you will be having the data in the local and a Data Page of type Page List (which gets created by default). This data page can be used in your use case.
