What are inconsistent text casing?

Inconsistent casing appears when the same value is written as london, London, and LONDON. It fragments grouping, inflates unique counts, and hides duplicates. RxLint detects case inconsistencies so you can normalize columns quickly.

Frequently asked questions

  • Why does casing inconsistency matter?

    Case-sensitive systems treat differently-cased strings as separate values, which breaks aggregations and causes false duplicates.

  • Can RxLint normalize casing automatically?

    Yes. Use quick fix to convert affected values to lowercase, uppercase, or capitalized format.
