Good to have another tool for csv debris management. Especially those multigigabyte gifts that need to be in the database “yesterday”. This has happened several days or weeks in a row more times than I can count. And no, people won’t provide such things in sqlite or something sane.
I feel like I should also recommend this: https://digital-preservation.github.io/csv-validator/
I think something like this rewritten in go would be great.
