An update of sorts. BP Group Organiser looks good, but there’s minimal documentation and it doesn’t look like it’s been updated in a coupe of years. I got it to work eventually after lots of tinkering with the CSV file. The same author has written an interesting plugin for creating Group hierarchies too, although it is also somewhat out of date.
Anyway, I’ve been experimenting with
I prefer WP All Import, which has a much larger number of installs. I’ve only so far spent a couple of hours with the free version, but it appears to import metadata into almost any WP field (you have to set up the mapping yourself), plus it can also import users, and also imports any product info into WooCommerce.It also works with ACF too. Costs $99 / $139 / $199.
