Okay, have corrected this:
One "issue" identified in trying to make it possible to import the categories/categoriesmeta files without all columns/fields included that if the description field of the applicable file is not included then a SQL error is expected at this time. I realize this is probably the field most desired to be removed if any are, but in developing that code, it looked "too easy". :) a better/appropriate process used for or similar to the products description needs to be incorporated.
Still welcome testing of the updates and identification of any issues.
