Hey,
Based on my understanding, there is an option called range in the excel dataset wherein you can mention from which row you want to read the data. So in your case you can start from 2nd row to read the sheet.
Else you would have to write a custom code for reading and converting the execl via batch job or Azure function etc.
@PRADEEPCHEEKATLA ,@KranthiPakala-MSFT : any thoughts on this or please correct me if I am wrong
