This link has several CLR ports of standard libraries: https://github.com/orgs/clojure/repositories?q=clr There's one for clojure.data.json, but not csv it seems

Okay, I have it forked and modified. It loads. The tests run. https://github.com/dmiller/data.csv I don't have time right now for an official release, but you could just take the one source file and drop it into your source. To make it an official release, I have to get it packaged for Nuget. That doesn't take long, but I really don't like to do that until we decide officially where its home will be. Regarding its final home, I made all the changes as conditionalizations, so this source will load under both Clojure and ClojureCLR. Sometimes, in situations such as this, the folks at Clojure headquarters will accept my changes and fold them into the original repo. (That includes the extra files I need for the Nuget packaging.) Most times, we create a separate repo, which in this case would be clr.data.csv. I'll check in with headquarters and let you know when it has a home. In the meantime, I hope the expedient of just copying the file will serve you. (@U064X3EF3, this is the bit of business I referred to in my email from yesterday.)

Yes indeed, that works fine for us. Thank you!

Much appreciated!
