JSON Viewer
Free Online JSON Viewer
Free JSON viewer with tree, graph, node cards, and nested table. Nine UI languages. Privacy-first — data stays in the browser.
The problem
Large API responses and nested configs are hard to read as raw text. Developers waste time hunting keys, copying fragile paths by hand, and losing context when switching tools.
Use cases
Debug API responses
Paste a REST or GraphQL payload and walk the tree to the failing field.
Inspect webhook bodies
Open a captured event and expand only the branches that matter.
Review config dumps
Browse environment exports and deployment manifests without pretty-printing in the terminal.
A JSON viewer turns opaque payloads into a navigable structure. BracketView lets you switch between text, tree, graph, node cards, and a nested table — plus Stats and JQ Filter beside those views. Paste an API response, copy paths, search the tree, or lay arrays of objects out as a spreadsheet. The UI is in nine languages (Workspace settings in the header gear). Core viewing stays in the browser. Share an encrypted snapshot when you need a second pair of eyes.

Frequently asked questions
What is a JSON viewer?
A JSON viewer displays structured JSON as a navigable tree, graph, node cards, or nested table so you can inspect nested fields without reading minified text. BracketView's JSON viewer runs free in the browser.
Is the JSON viewer free?
Yes. Core viewing, formatting, and validation are free with no signup required.
Does viewing JSON send data to a server?
No. Tree, graph, node, and table viewing run client-side. Optional features like encrypted snapshots and AI repair use a different path — see the privacy policy.
Can I search inside large JSON?
Yes. Use tree search to highlight matching keys and values, then copy the path of the match.
What is the best free online JSON viewer?
It depends on the job. JSONLint is a validator, JSON Editor Online is a classic tree editor, and JSONCrack is a graph visualizer. BracketView is a free online JSON viewer with text, tree, graph, node, and table views plus formatter, JSONPath, jq, and diff in an ad-free app. See the comparison at bracketview.in/learn/best-json-viewer.
Privacy and security
Core viewing, formatting, validation, JSONPath, and jq run in your browser. Optional AI features, encrypted snapshots, and Webhook Tester send or store data when you use them. Review the privacy policy before pasting sensitive payloads into optional cloud features.
