Hi all. I’ve just created a new PR at [1].
Basically, it skips headers which are “blank” (empty). Sometimes, the Excel file contains empty columns at the end, that would be processed as “normal” columns, but, as they have no property name on the header (is empty) a NullPointerException is thrown. Some weeks ago I did a similar commit for skipping empty rows instead of empty columns (as on this one). Please, any committer, review and merge if possible in order to keep all team synched. Many thanks! Oscar [1] https://github.com/isisaddons/isis-module-excel/pull/11
