How can I export ALM test cases and attachments to Excel file for import into Zephyr Squad?

I looked into similar requests and do not think this has been solved.  I am trying to export from HP ALM into Zephyr Squad.  To do so I need an Excel file with test cases and a repository of attachments that can be imported into Jira/Zephyr Squad. 

There does not seem to be a way to export test cases with attachments in ALM.  Are there any solutions, ideally not requiring custom development?  If custom development is needed, are there any resources than can help?
