What Is a JSON Formatter?
JSON (JavaScript Object Notation) is one of the most widely used data formats for APIs, web applications, mobile apps, and software development. However, JSON data can become difficult to read when it is compressed into a single line or contains syntax errors.
A JSON Formatter is an online tool that automatically organizes JSON data into a clean, structured, and human-readable format. It helps developers, students, and data analysts quickly understand and work with JSON files.
