I admit I didn't read all of your code. It's a mess and there's too much code for your question. It gives you some kind of error or what?
Anyway, if you just want to export a table showing some data, I suggest you to create a .csv file instead of using MS Excel. It's much more easier to code, faster during execution, and the output file is portable
