Find And Delete Quotation Marks At The End Of A String

I'm using a query that dumps information into Excel. The query automatically creates a formula in each each cell. For instance if the first value in the query showed FUNSTUFF, after dumping it into Excel, the contents of the cell would show ="FUNSTUFF". I can just use a find and replace to get rid of the leading =", but sometimes the values of the cells are supposed to have a quotation mark, so using the same method to remove the trailing quote won't work. I need a way to search each cell, check if the last character in the string is a quote, and if it is, delete it.
