# DimensionHeader

- [JSON representation](https://developers.google.com/analytics/devguides/reporting/data/v1/rest/v1alpha/DimensionHeader#SCHEMA_REPRESENTATION)

Describes a dimension column in the report. Dimensions requested in a report produce column entries within rows and DimensionHeaders. However, dimensions used exclusively within filters or expressions do not produce columns in a report; correspondingly, those dimensions do not produce headers.
