How to import content for content types with user-defined fields I've got a large amount of data I would like to turn into pages in Drupal. Most of the data to import correspond to custom fields I created in a new content type (let's call it directory).

For example, I have things like zip code, address, state, etc. that I would like to import as directory content.

I've been working with the feeds module, but so far I haven't been able to figure out if it can map to custom fields in a content type (I'm beginning to suspect that it cannot).

I'm using Drupal 7
I suggest you look into migrate module. This module is very flexible, very well documented and can  easily handle  and ease the pains of content migration.  Custom content, users, comments, etc .. and just about whatever you throw at it can be set up as 'migration tasks'.

Good-luck!
