# Overview of Data Profiler
|
|||
|
|
|
|||
|
|
The profiler in OpenMetadata helps to understand the shape of your data and to quickly validate assumptions. The data profiler helps to capture table usage statistics over a period of time. This happens as part of profiler ingestion. Data profiles enable you to check for null values in non-null columns, for duplicates in a unique column, etc. You can gain a better understanding of column data distributions through the descriptive statistics provided.
