What about using an XML editor that opens the file as an excel sheet, but you are allowed to save the xml and keep its formatting??
My issue: if I open the xml file in excel, and then save (keeping as xml), somehow the file loses its formatting, and then when I try to load it into an xml reader it says the xml file format is corrupted. So the solution I've working is to export the file from excel which gives me a lot of work.
What I really want to do is open the xml file in a program that will allow me to work on it as a excel file, but when I save it keeps the xml logic.
