Prettify JSON

Prettify JSON lets you format and clean up raw JSON for readability. Paste or import your JSON, then tweak options like key sorting and Unicode escaping. The Prettify JSON tool shows live output with real-time formatting, error checking, and export support.

Paste your input above or import a file below.

How to Use:

  1. Paste your unformatted JSON into the Input JSON box or use the Choose File button to import a .json or .txt file.
  2. The formatted result will appear instantly in the Prettified Output box.
  3. Use the toggles in the Options box to:
    • Escape Unicode for compatibility
    • Sort keys alphabetically
    • Show parse errors if the input is invalid
  4. Copy the result with Copy Output, or download it with Export to File.
  5. Click Clear All to reset everything and start fresh.

What Prettify JSON can do:

Prettify JSON turns messy, minified, or unreadable JSON into something easy to work with. You can sort keys, escape special characters, and even detect parse errors on the fly. It’s perfect for debugging, cleaning API responses, or just trying to make sense of poorly formatted data. The tool shows you the result live as you type, flashes on update, and gives you a live character count so you can keep track of how big your JSON is.

Example:

Input:

{"name":"Alice","skills":["JS","PHP"],"location":{"zip":12345,"city":"Wonderland"}}

With Sort keys on, output becomes:

{
  "location": {
    "city": "Wonderland",
    "zip": 12345
  },
  "name": "Alice",
  "skills": [
    "JS",
    "PHP"
  ]
}

Common Use Cases:

When you’re handed an ugly API response or working with config files that are one long line, Prettify JSON gives you structure fast. It’s useful for developers who need to review, debug, or modify JSON by hand. Escape Unicode for cross-system compatibility, sort keys for consistency, or just spot issues early with inline error feedback.

Useful Tools & Suggestions:

To clean up messy input first, Unstringify JSON can be used to turn a raw string into actual structure. Then, once it’s prettified, Highlight JSON Syntax helps bring out the formatting so it’s easier to read and share.
