Import CSV with FeedMe - multiple categories
You can do this with CSV by setting a dataDelimiter in a config/feed-me.php files (see docs).
If you set the dataDelimiter to be | for example, then your CSV could be:
&quot;title&quot;, &quot;Categories&quot;
&quot;Some title&quot;, &quot;Category1|Category2&quot;

Doing this should let you import multiple categories from CSV.
