Data Quality Rule Builder
Evaluate required, unique, type:number/integer/boolean/string, min, max, oneof and regex rules against exact cells. Unique flags subsequent repeats; whitespace is not normalized except required. User regex runs only in a deadline-limited Worker. Limits: 32 KiB each, 999 records / 10,000 cells / 100 rule lines / 20 tests per line / 256-char regex / 1,000 violations.
