JSON Viewer
Interactive ExplorerVisualize, navigate, and inspect JSON data in an interactive collapsible tree view, formatted code, tabular grid, and minified mode with search filtering and instant JSONPath copying.
Enterprise JSON Inspection & Navigation
JSON (JavaScript Object Notation) is the de facto standard format for REST APIs, serverless responses, and application configs. When payloads grow to thousands of lines, identifying nested keys or validating syntax manually becomes tedious. JSON Viewer provides 4 specialized inspection lenses:
Expand and collapse nested arrays or objects with real-time JSONPath tracking and type-colored badges.
2-space indented beautified layout ideal for clean copying into source code, IDEs, or documentation.
Converts arrays of JSON objects into structured tabular columns for easy spreadsheet-style scanning.
Strips whitespace and newlines for maximum compression before network transmission or disk storage.
Frequently Asked Questions
Is my JSON data private and secure?
Yes. 100% of JSON parsing, tree node rendering, formatting, and filtering happens locally in your web browser. No payload data is ever uploaded or transmitted across the network.
How does JSONPath copying work?
Click any row or key in the interactive Tree View. The breadcrumb path bar above the tree automatically updates with the exact accessor syntax (e.g., root.data.endpoints[0].path), which you can copy with one click.
Can I upload large JSON files?
Yes. Click the "Upload" button to select a local .json file. The browser streams the text directly into memory without server file limits.
