What is JSON Formatting?

JSON (JavaScript Object Notation) formatting transforms compact, hard-to-read JSON data into a well-structured, indented format. This makes it easier to read, debug, and understand complex data structures. Our formatter preserves all data while adding proper whitespace and line breaks.
