How it works
Paste or import a JSON file
Copy and paste your JSON to the input editor or load a file from your device with a .json extension. The included sample JSON can be loaded to test the tool.
Format, Minify, or Validate
Use Format to pretty up your JSON, Minify to strip out any unnecessary whitespace, or Validate to catch any syntax errors in your JSON. Choose the desired indentations (2 spaces, 4 spaces, or tabs).
Copy or Download
Take a look at what you created in the output pane. Copy to your Clipboard or download as a JSON file.
- Benefits
What makes our JSON Formatting Tool special?
Format JSON Instantly
Convert compressed or hard to read JSON to clean, properly indented and readable code.
Validate JSON Syntax
Look for syntax errors in JSON and know exactly where and on which line a problem lies.
Minify JSON
Trim away any unnecessary spaces and line breaks to get a compact JSON that can be used for data transfer and storage.
Choose Your Indentation
Write JSON with 2, 4, or 2 tab indents.
Learn about JSON as a Tree
Use the Tree view to browse a hierarchy of objects and arrays in an expandable structure.
Exports and imports JSON
Import JSON files directly to the tool and copy or download the result (formatted or minified).
- Use cases
JSON Formatter Popular Use Cases
API Development
Return API responses in the form of JSON that is easier to inspect, understand and debug during development.
Debugging JSON
Detect syntax errors, like missing brackets, comma errors, or incorrect values, with JSON validation.
Web Development
Configure JSON (including format configurations, API data, JavaScript objects, and others) in web applications.
Data Analysis
Use formatted code or tree view for large or nested JSON structures to make them more easy to inspect and comprehend.
Configuration Files
Make JSON configuration files more readable and maintainable.
API Response Testing
Simply copy and paste the API responses into the Formatter to instantly check the structure of those responses and detect invalid JSON.
Learning JSON
Learn to use a formatter to decipher JSON objects, arrays, nesting, indentation, and syntax.
Sharing JSON
Before sharing the JSON data with developers, teams, clients or technical support, clean and format it.

What you can do with our JSON formatter?
JSON (JavaScript Object Notation) is a lightweight data exchange format, which is used to transmit structured data between applications. While JSON is machine-readable, compact JSON can be challenging for humans.
A JSON Formatter formats JSON object, array, keys, and values into a readable structure by adding indentation and line breaks.
For instance, a mini JSON like:
{"name":"John","active":true,"skills":["HTML","CSS","JavaScript"]}
Can be structured to be more readable:
{
"name": "John",
"active": true,
"skills": [
"HTML",
"CSS",
"JavaScript"
]
}

JSON Code View vs Tree View
Code View
The Code view is a view for developers to read or copy the actual structure of the JSON code, which is formatted with indentation and line breaks.
Tree View
JSON is displayed in the Tree view as an expandable structure. Explore nested objects and arrays without searching through a big paragraph of text.
Read, inspect, edit or debug your data in JSON format. Create a minified version of JSON – for when you need a very compact version without space at the end of the line or the beginning of the document. In cases of deeply nested JSON data, tree view can be helpful.
- Troubleshooting
Common JSON Formatting Problems & Fixes
Invalid JSON Syntax
JSON is a strict syntax language. Typically, you will have a problem with commas, brackets, braces or quotation marks. Use the Validate button to find the error.
Trailing Commas
Trailing commas are not allowed in objects or arrays in JSON. Strip the unnecessary comma off and re-test the JSON for validation.
Single Quotes
All property names must be quoted and all string values in standard JSON must be enclosed in double quotes. Use double quotes instead of single quotes as appropriate.
Missing Closing Brackets
Each pair of { and } or [ and ] must match. Structure validation can be used to find where the structure is invalid.
Unquoted Property Names
The name of the property in a JSON document must be a string, typically in double-quotes. For instance, you can specify "name": "John" and not name: "John".
Difficult-to-Read JSON
Minified JSON is hard to see by the naked eye. Automatically insert indentation and line breaks with Format JSON.
Large JSON Structures
It might be difficult to navigate in the code view for deeply nested JSON. Explore objects and arrays more easily using the Tree view.
Need Compact JSON
Minify to make the formatted JSON file smaller if there is extra whitespace in the file.

JSON Explained
What Is JSON?
JSON (JavaScript Object Notation) is a lightweight text based representation that's used to store and pass structured data. It supports objects, arrays, key-value pairs, strings, numbers, booleans and null values.
JSON is used in a wide variety of applications including software systems, configuration files, applications, APIs, and websites.
What is JSON Formatting?
Indentation and line breaks are added to the JSON to make it easier for people to read, this process is called JSON formatting.
A formatter does not have to alter the actual information in a valid JSON. Rather, it creates a more streamlined organization of the existing structure.
What is JSON Validation?
JSON validation is checking if a JSON document conforms to the required JSON syntax. Validation can detect the location of the error if there is an error in the JSON so that you can correct it.
What is JSON Minification?
JSON Minification: Clean up line breaks, unnecessary white spaces and indentations from JSON. This yields a smaller, more compact representation which may be beneficial when sending or storing data.
In what situations do you need to Format, Validate or Minify JSON?
Use Format JSON if you must have readable and structured JSON for dev and debugging.
To test if your JSON has been written properly, select Validate JSON.
Use Minify JSON to get a JSON representation without any unnecessary whitespace.
When you want to see the nested JSON objects and arrays, use Tree View.
