Hi, I'm Robert and I'll be helping you with your computer question.
i just tried that on my copy of word and excel under windows 10
i dont see any "gobbledy gook"
though there is a place where you select a sheet or table after you open the xl file
could you maybe send me the excel sheet to look at ?
or if you are willing to pay a little bit extra i can log into your computer remotely to do it with you.
