Debug, Validate & Understand JSON Instantly

The BracketView JSON workspace at app.bracketview.in is ad-free — including the free tier. This marketing website (bracketview.in) may display third-party advertisements to help support free core tools. You can decline advertising cookies via the site banner.

BracketView is freemium. Core workspace tools — viewer, formatter, validator, tree, graph, JSONPath, diff, schema, and Webhook Tester — are free with no signup required. Free accounts include 5 MB uploads, 5 snapshot links per month, 20 AI actions per month, and Webhook Tester with 3 endpoints, 25 requests each, and 2-day retention. Pro unlocks unlimited AI, 50 MB uploads, unlimited encrypted snapshot links, and higher webhook caps.

Viewing, formatting, and validation run locally in your browser whenever possible. BracketView is privacy-first: core tools are 100% client-side. Snapshot links, AI-assisted features, and Webhook Tester captures follow a different data path — review the privacy policy before using those with sensitive data.

Pro unlocks unlimited AI across repair, mock data, jq assistant, and conversion helpers; uploads up to 50 MB; Performance Mode for large JSON payloads; unlimited encrypted snapshot links with snapshot links up to 2-hour expiry; Webhook Tester with 25 endpoints, 5,000 requests each, and 30-day retention plus encrypted share of a single capture; and priority email support. Pro is $3/month or $2.25/month billed annually.

Performance Mode is a Pro-only workspace setting that optimizes parsing and rendering for large JSON files (up to 50 MB). It keeps tree, graph, and editor views responsive when you work with heavy API responses, exports, or log dumps. Free accounts see Performance Mode disabled — upgrade to Pro to turn it on.

Free accounts can upload documents up to 5 MB. Pro raises the limit to 50 MB for larger API payloads, exports, and log files.

BracketView is a free online JSON viewer with advanced features including tree view, graph view, JSONPath queries, JQ filters, JSON diff, schema validation, type generation in TypeScript/Python/Go/Rust, and AI-powered repair — all running in the browser with no install required.

Paste your JSON into BracketView at app.bracketview.in. The real-time validator instantly highlights bracket mismatches, trailing commas, and unquoted keys as you type. For schema validation, use the Schema Validator tool to confirm data against OpenAPI definitions or custom JSON Schema rules.

Open BracketView, paste your raw JSON, and click Format. The formatter beautifies JSON with readable indentation and consistent spacing in one click. You can also minify JSON for production payloads.

Yes. BracketView supports JSONPath expressions (like $.store.book[*].author) and a full JQ filter playground powered by WebAssembly. The AI Query Assistant lets you describe what you need in plain English and generates a valid jq filter instantly.

No, not for core tools. Viewing, formatting, validating, and querying JSON with JSONPath or JQ run 100% locally in your browser — your data never leaves your device. AI-assisted features (like AI JSON repair) and snapshot links do send data to process the request; review the privacy policy before using those with sensitive data.

BracketView's AI JSON Fixer analyzes malformed JSON — missing brackets, trailing commas, unquoted keys, unescaped characters, and truncated payloads — and reconstructs valid, well-formed JSON while preserving your original data and structure as closely as possible. It's designed for messy API responses, hand-edited configs, and copy-pasted payloads that fail standard parsers.

Webhook Tester gives you a disposable public webhook URL so you can capture and inspect live HTTP requests from Stripe, GitHub, Shopify, or any service that POSTs events. Free: 3 endpoints, 25 requests each, 2-day retention. Pro: 25 endpoints, 5,000 requests each, 30-day retention, plus encrypted share of a single capture. Endpoints are public and history is short-lived by design. Open it at app.bracketview.in/webhooks.
