BracketView is a freemium online JSON viewer, formatter, validator, and AI-powered repair tool. The free tier includes the full workspace; AI features have monthly limits unless you upgrade to Pro.

How does the AI JSON fixer work?

BracketView's AI JSON fixer analyzes broken JSON and repairs common syntax errors. Paste JSON and use Fix with AI; usage follows free-tier or Pro limits.

Is my JSON data secure with BracketView?

For viewing, formatting, and validation, JSON stays in your browser. Optional snapshot links and AI repair handle data differently when you use them—see our privacy policy.

About BracketView

BracketView is a freemium online workspace for developers, analysts, and students who handle API responses, configuration files, and exported data every day. Whether you are debugging a REST endpoint, reviewing a webhook payload, or cleaning up a hand-edited config, you get formatting, validation, tree exploration, and query tools in a single tab. The free tier includes the full editor; optional Pro plans raise AI and large-file limits. See all features and pricing for details.

How to use BracketView

Open bracketview.in and paste your payload into the editor, or upload a file from disk. Click Format to run the built-in json formatter, which adds readable indentation and colour-coded syntax. The json validator runs as you type, surfacing bracket mismatches, illegal trailing commas, and unquoted property names before you copy results back to your app. Switch to the tree panel to collapse noisy branches, search for keys, or open graph view for a high-level map of relationships.

When you need to pull a slice from a large document, open the JSONPath or JQ playground. JSONPath expressions such as $.store.book[*].author return matching nodes instantly, which is ideal for inspecting API responses without writing a script. Pair validation with the schema tools to confirm payloads against OpenAPI or custom definitions, or generate a draft schema from an example object for documentation.

Broken syntax from log files or third-party exports is common. Use the AI JSON fixer to repair missing commas and quote issues, then re-validate before committing changes. For release reviews, paste two versions into the diff tool to see exactly which fields changed. You can export formatted text, convert to CSV, or share encrypted snapshot links with teammates when a live demo is easier than attaching files.

BracketView is designed for privacy-conscious workflows: viewing, formatting, and validation execute locally in your browser whenever possible, so routine inspection does not require uploading sensitive production data. Snapshot links and AI-assisted repair follow a different data path—read our privacy policy before using those features with regulated information. No desktop install is required; the app runs on any modern browser on Windows, macOS, Linux, Android, or iOS.
