JSON Indenter – Format JSON with Custom Indentation
The JSON Indenter is a free online tool that lets you format and beautify JSON data using custom indentation levels.

Why Use a JSON Indenter?

This makes it easier to identify key-value pairs, nested objects, and array items at a glance. Unlike typical formatters, this tool allows you to select the indent size, giving you flexibility across projects or style guidelines.
