Yes! Thank you! We're using the d3 CSV parser for our CSV upload functionality [1] but are having a ton of issues with performance and cross-browser support. Can't wait to try this out.
Cool, good luck! Disclaimer: some features definitely won't work in older browsers.
I saw your service on HN a while back. It generated some excitement among us here at SmartyStreets, which also uses Papa to process customers' lists without requiring them to send us their whole file. I think these are great use cases.
