API Explorer Pro - React JSON Data Explorer

API Explorer Pro is a production-ready React component for exploring and presenting complex JSON data through connected Tree, Smart Table and Raw JSON views.

It is designed for dashboards, admin panels, developer tools, API response viewers, internal applications and other React projects that need a polished way to inspect JSON data.

The component accepts normal JavaScript/JSON data and does not require a backend service.

Key capabilities include:

• Interactive Tree View for nested objects and arrays • Smart Table detection for arrays of structured objects • Formatted Raw JSON view with syntax highlighting and line numbers • Global search across keys and primitive values • Search result navigation with automatic tree expansion • JSONPath display and copy support • Value Inspector for selected data • Table filtering, sorting and pagination • Copy Table and CSV export • Copy and download JSON • Configurable sensitive-data masking • Custom primitive value rendering • Selection, view and table-source callbacks • Light and Dark themes • Responsive layouts • Keyboard and accessibility support • TypeScript definitions • React 18 and React 19 support • No runtime dependencies

API Explorer Pro includes readable and editable TypeScript/TSX source code for customization, a prebuilt package for quick integration, documentation and examples.

The component is backend-agnostic. Data can come from REST APIs, GraphQL, local JSON, application state or any other source as long as it is provided to the component as JavaScript data.

Large JSON datasets are handled with bounded rendering strategies to avoid unnecessarily rendering very large structures into the DOM.

The included live demo demonstrates realistic Customer API data, complex nested data, search, masking, table operations, exports, themes and the connected inspection workflow.
