Anyone that stumbles across this post in need of help with importing a CSV of posts into WP, try out this plugin. It allows you to add columns for all of the default WP fields like the_title, the_content and so on. It also allows any custom fields to be added as columns, so ACF is completely compatible.
In fact, you can even stick a repeater field into the CSV. I done this for a recent site.
You’d have the columns like:
repeater_0_text, repeater_1_text, repeater_2_text, repeater_3_text
And then another just called ‘repeater’, with the amount of sub-fields (in this example, the value would be 4).
Give it a try! Hope this helps someone one day.
