I have an excel file that has a column of mobile numbers. The number are showing as (189) xxx-xxxx. I want to add this to the phone number +1 and modify the cell to +1-189-xxx-xxxx. what I try to put +1 and modify the cell and click enter to go to the cell below I the cell behaves as if I am adding the contents from the cell below. Its weird.
Is there another format other than excel or csv I can open it and make the changes on the phone list.
Can you please help me.
