Yup. We’ve been using this data for a while to render e-filed 990s on our site and to extract highly paid employees. Now we just strip the markup out and toss it all into elasticsearch for search. It’s really interesting to surface things like grants.

I will say for personal analysis that the schema has a habit of changing, and things like grants can appear in multiple places depending on the context. What’s more, just 2/3rds of nonprofits e-file now (and I’m sure fewer and fewer the further back you go) Just some things to look out for.

If you’re interested in processing the 990 XML data though, check out the truly excellent irsx: https://github.com/jsfenfen/990-xml-reader
