Online JSON Minifier

JSON minify

JSON minification is the process of removing unnecessary characters and whitespace from a JSON (JavaScript Object Notation) string to make it more compact. This minification reduces the size of the JSON data, which can be beneficial for various purposes, such as improving network performance by reducing data transfer size.

JSON minification typically involves the following transformations:

Removing Whitespace: All unnecessary whitespace characters (spaces, tabs, line breaks) are removed. These whitespace characters are not required for the structural integrity of the JSON data but are added for human readability.

Removing Comments: Comments are removed from the JSON string. Unlike JavaScript, JSON specification does not support comments. However, some JSON parsers allow certain types of comments, but they are usually stripped during minification.

Removing Trailing Commas: Trailing commas in arrays or objects are removed. In some programming languages, trailing commas in lists or arrays are allowed, but JSON specification does not permit them.

Reducing Number Precision: If a number does not require a certain level of precision, it may be shortened by removing unnecessary digits after the decimal point.

Here's an example of JSON minification:

Original JSON:

{
  "name": "John Doe",
  "age": 30,
  "email": "johndoe@example.com"
}

Minified JSON:

{"name":"John Doe","age":30,"email":"johndoe@example.com"}

JSON minification is often performed as a preprocessing step before transmitting JSON data over the network or storing it in a database to reduce storage requirements and improve performance. Various online tools and libraries are available for minifying JSON strings in different programming languages.
