JSON फॉर्मेटर

JSON Formatter क्या है?

A JSON formatter (also called a JSON beautifier or JSON pretty printer) takes raw, compressed, or poorly formatted JSON and reformats it with proper indentation, line breaks, and spacing. The result is human-readable JSON that's much easier to read, debug, and share. This tool also supports minification — removing all whitespace to produce compact JSON optimal for APIs and production environments.

JSON Formatter कब इस्तेमाल करें?

• Debugging API responses — API responses are often minified. Pasting them into the formatter instantly gives you readable, indented JSON to find the data you need.
• Code review and documentation — Properly indented JSON is much easier to read in code reviews, README files, and internal documentation.
• Config file editing — Configuration files like package.json, tsconfig.json, and appsettings.json are JSON. Keeping them well-formatted prevents accidental syntax errors.
• Minifying for production — Removing whitespace reduces the file size of JSON payloads, improving API response times and reducing bandwidth usage.

Tree व्यू: विज़ुअल JSON ब्राउज़िंग

The Tree View tab renders your JSON as a collapsible tree. Click the arrow next to any object or array to expand or collapse it. This is especially useful for deeply nested JSON — you can fold sections you don't need and focus only on the part of the structure you're working with. Each node shows the number of keys or items it contains when collapsed.

Stats: JSON संरचना विश्लेषण

The Stats tab shows a full breakdown of your JSON: total objects, arrays, string values, numbers, booleans, null values, total keys, maximum nesting depth, and file size. This is helpful when analyzing large or complex JSON structures — for example, to understand the shape of an API response before writing code to process it.

ऑटो-फ़िक्स: Invalid JSON ठीक करना

The Auto-Fix button attempts to repair common JSON mistakes automatically. It fixes trailing commas (which are valid in JavaScript but not JSON), converts single-quoted strings to double-quoted, adds missing double quotes around unquoted property keys, and replaces undefined values with null. After fixing, the corrected JSON is written back to the input so you can see exactly what was changed.

गोपनीयता

All formatting, validation, and analysis happens entirely in your browser using JavaScript. Your JSON data is never sent to any server, stored, or shared. You can safely format sensitive data like API keys, private config files, or customer records.
