How do you Minify JSON using Python?

Python has built-in support to minify JSON with the JSON Module. This is a quick way to achieve it. This script reduces the JSON file size by eliminating unnecessary whitespace:

				
					import json

data = {
    "name": "John Doe",
    "age": 30,
    "city": "New York"
}

minified_json = json.dumps(data, separators=(',', ':'))
print(minified_json)

How do I minify JSON using npm?

If you use Node.js you can easily install a JSON Minifier by using npm:

				
					npm install jsonminify -g

Then, you can use it like this:

				
					const jsonminify = require("jsonminify");

const json = `{
    "name": "John Doe",
    "age": 30,
    "city": "New York"
}`;

console.log(jsonminify(json));

The method can be useful to developers who work frequently with JSON within JavaScript environments.

What is the Best Way to Decompress JSON Online?

You can decompress JSON using the same tools you use to format it. You can paste the minified JSON into websites like JSONLint and FreeFormatter to expand it and make it readable.

JSON Formatter & Stringify Online

You may need to format JSON rather than minify it. JSON formatters make JSON more readable by adding proper spacing and indentation. JSON Formatter Online and other tools offer JSON Stringify Online, a feature that converts objects to JSON strings. JavaScript Example:

				
					const obj = { name: "John", age: 30 };
console.log(JSON.stringify(obj, null, 4));

The JSON is formatted with 4 spaces of indentation.

Use JSON Compression to Store Files Efficiently

You can compress JSON files using:

Online Tools (like JSON Miniter)
Command-line Tools (gzip compression)
Python’s Gzip Module

Python Example for compressing JSON:

				
					import json
import gzip

data = {"name": "John Doe", "age": 30, "city": "New York"}
json_str = json.dumps(data)

with gzip.open("data.json.gz", "wt") as f:
    f.write(json_str)

It is possible to reduce the amount of storage by using this method.
