L. 115-435). This inventory enhances information discovery, data usability, and government transparency by providing public visibility into data assets from all HHS Divisions.
The HHS Data Inventory is available in multiple formats, including machine-readable JSON, Excel (CSV) files, and open APIs for seamless integration and automated retrieval.
