@Otakumouse: Yes, it should include all ACF fields, such as Images. It's been most heavily tested with content repeaters (Repeater Field, Flexible Content Field, etc) but should work with any field type.

Big thanks for this gist! I was wondering how to do this exact thing and this works great.

However, I was receiving a Creating default object from empty value on line 61, so I made a fork with some object initialization before then to ensure there's an object in place to write to.

Will this ever work with category specific custom fields? The meta field is empty for ACF fields set for taxonomies
