📋 JSON Formatter

What is JSON Formatting?

JSON (JavaScript Object Notation) is a lightweight data interchange format widely used in Web APIs, configuration files, and data storage. JSON formatting adds indentation and line breaks to compressed JSON data, making its structure clear and easy to read and debug.

When JSON data contains syntax errors, this tool automatically detects them and provides error descriptions with exact locations (line and column numbers). Minify mode removes all unnecessary whitespace to reduce data size, ideal for network transfer and storage.
