What is JSON and why use a JSON viewer?

JSON (JavaScript Object Notation) is a lightweight, human-readable data format used for configuration files, API responses, data exchange between systems, and structured data storage. JSON uses key-value pairs, arrays, and nested objects. While JSON is technically human-readable, complex nested structures, minified code, and large documents are hard to understand as raw text. Our JSON viewer formats, validates, and displays JSON with syntax highlighting, tree views, and collapsible structures for easy comprehension.

Is my JSON data safe and private?

Yes, absolutely. All JSON parsing, validation, formatting, and viewing happens entirely in your browser using native JavaScript JSON.parse() - there are no server uploads, database storage, or external API calls. Your data never leaves your device. This makes our viewer perfect for API keys, authentication tokens, OAuth credentials, sensitive configuration files, and confidential data structures.

Can the viewer validate JSON syntax and show errors?

Yes! The viewer provides real-time JSON syntax validation using native JavaScript parsing. Invalid JSON is highlighted with red error indicators, precise line and column numbers, and clear error messages describing the issue (missing commas, unclosed brackets, invalid characters, trailing commas, unquoted keys). Perfect for debugging hand-edited configs or malformed API responses.

What's the maximum JSON file size supported?

The viewer supports JSON files up to 50MB. We use efficient parsing and virtual rendering to handle large JSON documents with thousands of nested objects and arrays. Very large files (>10MB) may take a few seconds to parse and render depending on complexity and your device's performance.

Can I view minified or compressed JSON?

Yes! The viewer automatically formats minified JSON (single-line, no whitespace) with proper indentation, line breaks, and structure. Minified API responses, compressed configs, and machine-generated JSON are instantly beautified for human readability while preserving the exact data structure and values.

Does the viewer work with JSON from APIs and configuration files?

Yes, perfectly! The viewer handles JSON from any source: REST API responses, GraphQL results, Node.js package.json, VS Code settings.json, Firebase configs, AWS configs, Kubernetes manifests, and any application-generated JSON. It supports all valid JSON syntax including nested objects, arrays, strings, numbers, booleans, and null values.

Can I search through large JSON documents?

Yes! Use the search bar to find keys or values across the entire JSON document with instant highlighting. Search works in all view modes (Tree, Formatted, Raw) and is case-insensitive. Perfect for finding specific configuration values, API parameters, object properties, or data patterns in complex nested structures.

Can I copy formatted JSON to clipboard?

Yes! Copy the entire formatted JSON, specific nodes from tree view, or raw JSON source to clipboard. Paste into code editors, APIs, configuration files, or other applications. Formatting is preserved when copying, making it easy to extract and reuse JSON data or configurations.
