I'm looking for a website that can take multiple csvs/tsvs/jsons, generate SQL tables that I can run queries against, and that's shareable with others (invite people and have them run queries against the tables), and that's possibly free? I'm using this to interview people, and would prefer something that doesn't require them to download additional software/ can be accessed through the web itself.
I found these two websites, but they don't appear shareable/ are localized to your browsers instance.
Flatbase would be prefect, but it's signup and invite process seems to be broken. Invitation emails aren't being sent out, and signing up with a gmail/ outlook email breaks into a signup loop, so it isn't ideal. https://flatbase.io/
