How to Format JSON Online (Step-by-Step)
JSON is one of the most commonly used data formats in APIs and modern applications. But when JSON becomes long or minified, it becomes hard to read or debug. This guide explains how to format JSON easily using online tools like JSON Formatter, JSON Validator, and JSON Pretty Print.
Step 1: Copy Your Raw or Minified JSON
Take the JSON you want to beautify. Example:

Step 2: Paste into JSONHack Formatter
Open JSONHack JSON Formatter and paste your JSON into the editor. The tool automatically checks the JSON structure and highlights errors.

"python"
]
}
