I coud see many people are in hurry to provide the Answer without reading the actual problem.
so first of all i would like to repeat the quetion in layman language
1- I have two separate office 365 online excel 2016 work book. just reconfirming 2 seprate online workbook.
2- now i want refer excel Cell from workbook 1 (i.e. Sheet1:B3) in Workbook 2 sheet in any cell.
so here is the question what is the command or example which basically read office excel Oline : URL + sheet + Cell, and if i made any change in cell it should update accordingly.
