What is JSON Formatting?
JSON (JavaScript Object Notation) is a lightweight data interchange format widely used in web APIs, configuration files, and data storage. Raw JSON from APIs or minified sources is often a single long line that is difficult to read.
A JSON formatter (also called a JSON beautifier or pretty-printer) adds proper indentation and line breaks to make the structure visible at a glance. This tool also validates your JSON, catching syntax errors like missing commas, unmatched brackets, or trailing commas before they cause issues in your code.
You can choose between 2-space, 4-space, or tab indentation. The minify option removes all whitespace, producing the most compact representation for production use or network transfer.
