The quickest way to get a CSV file into Datasette these days is like this:
1. Put the CSV file in a Gist, e.g. https://gist.github.com/simonw/8a2494a3402450716f4c8129d280b...
2. Paste that into the "Load CSV" dialog on https://lite.datasette.io/ to get this shareable and bookmarkable URL: https://lite.datasette.io/?csv=https%3A%2F%2Fgist.githubuser...
I'm going to keep ticking away at making this as easy as possible for people (I have a paid SaaS product on the way, but I want people who just want to publish something small to free to be able to do so) but I'm interested in understanding what it would take to qualify as "no code" in your book.
