ORELS Viewer

ORELS Viewer is a static web application for validating and inspecting JSON files that follow the Open Real Estate Listings Schema.

The viewer lets a user choose an ORELS schema version, load a JSON file, validate it in the browser, and review the listings in a full-screen data table. Valid files are shown with filtering, sorting, pagination, and a full-screen listing detail view.
