Hello...

I am posting for the first time and hoping for some insight regarding an issue. I have an input file from a client formatted as an "xls" file. My company's application takes that file and processes it in order to return some additional information. We generate an output file that first just parrots back the input columns provided by the client. Generally that's a no brainer, but this time all of those cells have a little character after the text. I just tried to copy it here but it doesn't work. It's a little black diamond with a white question mark in it.

I don't know if it's a special hidden character. If so, I don't know how to get rid of it. It does not display in my input file.

I cannot return the file to the customer this way. Does anyone have any knowledge about this?
