Why record it

Cleaning decisions change results. When a number is questioned three weeks later, this record is the difference between a two-minute answer and a rebuild.

Frequently asked questions

Can GridMind produce this automatically?

The data cleaner reports rows kept and removed and profiles every column after cleaning, which covers most of the checklist.
