Hi Ahmad,
first you do not have option "ExcelToRecordList" and "RecordListToExcel" in client action
so you need to create a server action and take one input parameter as binary datatype and create a process for create record by exceltorecordlist
from client action you need to call this server action and pass binary data of file which you upload by widget.


Hope this will help you
