JSON Sort

What is JSON Sort

Use this JSON Sort tool to quickly and accurately sort JSON objects by key name, key value, or numerical values. You can sort JSON alphabetically, numerically, ascending, descending, or reversed. This online JSON sorter also works as a JSON formatter, pretty printer, and validator, ensuring your JSON data is properly structured and free of parsing errors.

This tool supports valid JavaScript Object Notation and helps make your JSON files easier to read, debug, and use for exchanging data between a client and server.

How to Sort JSON (Step-by-Step)

1. Enter valid JSON text
   Paste, type, or load your JSON input into the input area.
2. Select the sort method
   Choose to sort by key name, key value, or custom sort order. Sorting by key value requires specifying the key name.
3. Click the Sort / Convert button
   The tool will instantly generate sorted JSON text.
4. Download or copy your output
   After sorting is complete, click to download the sorted file or copy to clipboard.

This JSON sorter tool works instantly in the browser, requires no signup, and keeps your data secure—your JSON data never leaves your device.

What Is JSON and Why Is It Popular?

JSON (JavaScript Object Notation) is a lightweight data interchange format used to represent structured data using objects, arrays, strings, numbers, boolean values, and null. It is language-independent but closely resembles JavaScript object syntax.

Reasons JSON is widely used:

• Works seamlessly with modern programming languages
• Easy for humans to read and write
• Ideal for APIs, web services, client–server communication
• Fast for machines to parse and generate
• Excellent for data storage and configuration files

JSON supports arrays of objects, nested structures, and spare plain arrays, making it a flexible and universal format.

Using JSON in Web Applications

JSON is the standard for transmitting structured data between clients and servers. Web APIs frequently send JSON responses because it is easy to parse into a native JavaScript object using:

JSON.parse()
JSON.stringify()

This format is ideal for transferring data across the internet, storing configuration files, and building dynamic applications.

How to Sort JSON Objects Using Python

A JSON file is a common text-based format used across languages. Python can sort JSON objects using built-in functions, custom comparison logic, or modules like json.

Example: Sort JSON by value (JavaScript)

json.sort(function(a, b){
  return a.id - b.id;
});

This sorts an array of JSON objects using the "id" key. Any property can be used. Sorting behavior depends on the data type: String, Number, Boolean, Null, Array, or Object.

Sorting Using a Comparison Function

A compare function defines custom sort behavior:

function compare(a, b) {
  if (a < b) {
    return -1;
  }
  if (a > b) {
    return 1;
  }
  return 0;  // equal
}

This technique is commonly used to sort elements of an array in JavaScript based on a specific ordering criterion.

JSON Sort Alphabetically

Sorting JSON keys alphabetically does not change the underlying JavaScript value. The tool sorts keys while preserving array order unless sorting by a specific key. Arrays can be replaced in-place after sorting by a shared property.

How to Sort JSON Object by a Specific Key (JavaScript Example)

Because JSON data is often returned as an array of objects, you must apply the array sort() method directly to the collection:

// Comparer Function
function GetSortOrder(prop) {
  return function(a, b) {
    if (a[prop] > b[prop]) {
      return 1;
    } else if (a[prop] < b[prop]) {
      return -1;
    }
    return 0;
  }
}

Use this function to sort any array of objects by string, number, boolean, or mixed values.

Why Use an Online JSON Sort Tool?

This JSON sorter helps you:

• Organize large or complex JSON files
• Quickly spot structure issues
• Validate JSON and detect errors
• Improve readability and indentation
• Generate cleaner output for development
• Work faster when debugging or formatting API responses

Because the tool runs in the browser, none of your data is sent to a server, offering complete security and privacy.
