.. lets assume there is some data in excel and Need to load into list…………

Hi Shruti,

Hope you doing well.

You could use the Data Loading activity to upload data into the system using CSV file.

Once you upload data into system you could save it some schema using Update Data activity (If you have schema already build)

If you want to create a list you could use Update List activity and directly create a List:
