So apparently, it exports pems. That's great. It doesn't export most attachments.
edit: This is apparently new behavior in 1password8. If you have upgraded to the very latest version, the .1PUX export does seem to finally solve this problem. But that's new - it was not true for any previous version.

14 .txtThis situation seems to contradict my previous assertion that AgileBits does a good job of documenting their file formats since I was unable to find the 1pif spec on their site
1Password's extensions getting worse with every update gets me closer each day though.
I'm waiting for someone to point out that BW's extensions are open source and are still a dumpster fire, but for me the difference is that BW started as a dumpster fire, so I don't feel compelled to bring their extension up to sane operating levels, whereas 1P's are _mostly_ right, and just need a tune-up here and there
