HPXML Validator

The HPXML Validator allows software developers to validate and inspect their tool's HPXML formatted data against the HPXML schema and its datasets.

The HPXML Validator allows software developers to validate and inspect their tool's HPXML formatted data. Users can upload HPXML files and check these files against the HPXML schema and its standard datasets for compliance (i.e., audit, upgrade, Home Energy Score, and Home Performance Certificate).

The validation tool returns specific error messages with feedback on missing elements. It also provides a searchable tree view of HPXML data to assist with navigating and inspecting errors. This tool is available through a website or an API that can be incorporated into HPXML data transfer workflows.

The HPXML Validator is located in the HPXML Toolbox, a website designed and managed by NREL.
