About JSON Viewer

Large JSON documents with deeply nested objects and arrays are difficult to navigate in plain text. A tree view transforms JSON into a visual hierarchy where you can expand and collapse sections, making it easy to understand complex data structures at a glance.

Our JSON Viewer parses your JSON and renders it as an interactive, collapsible tree with color-coded data types. Strings, numbers, booleans, and null values are each highlighted differently. All processing runs locally in your browser — your data stays private.
