Export Agents as CSV

UPDATE: Script method to do this is in the comments below.

ORIGINAL POST:

We often add groups of new agents and update existing ones, with various tags and other user options. An option to do so via bulk import/export CSV files would be amazing. Right now it's a messy combination of API calls and the bulk import option (https://support.zendesk.com/hc/en-us/articles/203661996-Bulk-importing-users-#topic_svw_jdl_dc) that doesn't have an equivalent export option so updating existing info is painful.

The User XML export option for this a bit overkill since I don't need our >100,000 end users' info - just the agents. For quickly updating a batch of users it takes too long to get the XML export (I'm still waiting on a report I requested >30 minutes ago). The format also doesn't match the CSV bulk import template.

It would also be great to have this available via a direct link as opposed to an emailed file.
