When I think of validation I think of receiving a data file and checking that all rows and columns are correct and generating a report about all the problems.

Does my thing have a different name? Where can I read up on how to do that best?

You can use the now widely adopted Great Expections[0] library, which fits exactly this use-case for data validation!

Thanks for the link. It looks really nice.

I see they’ve raised a lot of money. Does anyone know what their revenue model is?
