I'm sorry if this is basic for this room but I am ready to slam my head through a wall. I have received an attachment of a .csv file from a client and one of the fields is a tenant ID number that sometimes begins with 1 or more zeros. When I open the attachment it is opening in Excel and dropping the zeros. How can I open that up and keep the zeros. I need those leading zeros. Again my apologies if this is too basic for all of you.
