I was able to figure put how to get market depth in Excel. It turned out to be so easy.
Once Market Explorer is opened, it shows things like last bid/ask, last traded price and so on as default. If you right click on particular contract there are options to change view for this contract, one if which is market depth. Once the view is changed all that is left is to copy each cell and paste it in Excel via paste special (link). It displays 5 levels of DOM. As it turned out, pro license is not required.
