๐Ÿ“– JSON Formatter Examples Explained

What is JSON Formatting?

JSON formatting (pretty print) converts a minified single-line JSON string into a well-indented, human-readable format. For example, converting {"name":"John","age":25} into a multi-line indented structure for easy reading and debugging.

Common JSON Format Examples

  • User Profile: Object with name, email, age fields
  • API Response: Standard API return format with status, data, message
  • Config File: JSON with database, server, logging configuration
  • Nested Structure: Multi-level nested objects and arrays
  • GeoJSON: Geographic coordinate data in GeoJSON format

JSON Format Specification

JSON (JavaScript Object Notation) is a lightweight data interchange format. Key rules: keys must be wrapped in double quotes, string values must use double quotes, comments are not supported, and trailing commas are not allowed.

โ“ FAQ

What is JSON formatting?

JSON formatting (pretty print) converts a minified JSON string into a well-indented, human-readable format using 2 or 4 space indentation with line breaks.

How to validate JSON?

Paste your JSON string into the tool and click Format. If valid, the formatted result appears; if invalid, the specific error location and reason are shown.

What is the difference between JSON and JSONP?

JSON is a pure data format. JSONP (JSON with Padding) wraps JSON data in a callback function for cross-domain requests. Modern development recommends CORS over JSONP.

What data types does JSON support?

JSON supports 6 data types: string, number, boolean, null, object, and array. It does not support comments, dates, or undefined.

Will data be uploaded to a server?

No. All JSON formatting and validation is done locally in the browser. No data is sent to any server.
