Empty headers
What they are and how to fix them
What are empty headers?
Empty headers happen when one or more header cells are blank. Unnamed columns are hard to map, easy to misread, and often rejected by strict import pipelines. RxLint flags empty headers so you can give every column a clear name.

Frequently asked questions
Why are empty headers risky?
Many data pipelines map fields by header name. A blank header can cause dropped columns, incorrect mappings, or validation failures.
What is the best fix?
Rename empty headers to descriptive, unique labels that match your downstream schema and team naming conventions.
