Ah, Yes, I remember now why I didn’t use WPAI. It doesn’t work. With the ACF add-on installed and activated it asks me to create a field group when I’ve already done that. It doesn’t see any new groups created either.
It’s no problem chopping spreadsheets up into manageable chunks at least initially. Problems may occur though when trying to process updates from suppliers. I have over 300 of those and one gave me an update spreadsheet with over 250,000 rows. Naturally I won’t be trying to chop that up :-). I’ve really got to be able to automate that but i’ll test out howe it might wotk later. ISTR trying out WPAI but giving up on it. I’ll have another go.
