Showcasing Excel Formula within Workflow

[caltang]

I know that Danilang, TheOC had a thread about this a long time ago saying that if you import your Excel file as a zip, you get to see the contents of your file, and by extension of the nodes, you see the exact formula applied in the cell. 

my question is, if it’s a non standard data frame whereby the values start in Row 3 Column B, and some datasets existing elsewhere within the file, do we just get certain nodes and ignore the rest?
