Data tables are all over the internet, especially Wikipedia. sqanything lets you query the HTML tables in all your open Chrome tabs with SQL. You can send the results of your query to Google Sheets or just send all the tables on a web page to Google Sheets.
@asolovyov Your right, there's a lot of ways tables can be formatted so we're still working out the kinks! The first table on the page is not actually a table but a content box, which is why it doesn't work. Querying the next two tables on that page both work though if you want to give those a try. There's a lot of "pseudo" tables on Wikipedia that have a "table" tag but aren't actually data tables, so we're trying to hide those from the Schema so people don't try to query them. Thanks for trying it!
