Columns that do not match up with one of the import names will be ignored and the first line on the import result will be a list of the ignored columns

Useful Google Sheet calculations:

1. Look for a material in the suppliers name (use named ranges) =INDEX(Materialresultlist,MATCH(TRUE,ISNUMBER(SEARCH(Materiallist,B2)),0))
   1. Note ensure the list of materials is sorted longest at the top - then "Shiny Red" will be found before "Red"
   2. Export from the item Profile for Material to find a list of possible values for that material
2. If the supplier provides the name all in caps = Proper(a2)
   1. may need to adjust Ml to ml etc after
