Import csv file into Looker

Hi, I want to use data from a csv file like explores in Looker. I don’t seem to find the import function. Can you please help?
Thanks

You can only import map files to Looker, anything data-related has to be imported to your database/data warehouse

I believe the only way I can think of is using a third-party tool to generate CSV to SQL and then used a SQL Derived table to run it.

Not a pretty answer though.
