What is a JSON Viewer?
A JSON viewer displays JSON data in a visual, hierarchical tree structure rather than raw text. This makes it dramatically easier to navigate, understand, and explore complex nested JSON objects and arrays. Instead of scrolling through thousands of lines, you can expand and collapse sections as needed.
100% Private: All viewing happens in your browser. Your JSON data never leaves your device.

Frequently Asked Questions
A JSON viewer is a tool that displays JSON data in a visual, hierarchical tree structure rather than raw text. This makes it easier to navigate, understand, and explore complex nested JSON objects and arrays.
JSONPath is a query language for JSON, similar to XPath for XML. It provides a way to reference specific values within a JSON document using a path notation like $.store.book[0].title to access nested data.
Use the search box in the tree view to find keys or values within your JSON. The viewer will highlight matching results and automatically expand parent nodes to show matches in nested structures.
