I’m using the xls formatting nodes from Continental and I’m trying to automatically detect the last column in a file, so that I only select the header as “a1:d1” for example. I know how many columns I have in the file (4 in this example) but I don’t know if there’s an automatic way of transforming 4 into D, or 5 in E and so on.
Is there a node or other simple solution solution than a local dictionary?
