Show HN: Lightweight, open source FlatFile clone

Hi HN!

I built this for my own company, but I figured there might be a chance it will be useful for others too.

We explored Flatfile and they quoted us pretty insane prices: ~12k + 4k for every "shape" of import. Since we were looking for a solution to import 4 different types of data (users, locations, etc), it would've come out to about 28k / year.

But their product is fantastic, and so I figured I'd try to shamelessly copy their UX. It's not quite there yet in terms of aesthetics, but we will continue to invest in it since it's currently being used already in production with great user feedback.
