Minifying JSON with Python

Yesterday I wrote about Minifying JSON Ruby, but today let's talk about using Python instead.

Let's say that we have a nicely pretty-printed JSON file, such as:

{
    "key": [
        123,
        456
    ],
    "key2": "value"
}

If we want to minify the JSON, we can use the following one-liner:

python -c $'import json\nimport sys\nwith open(sys.argv[1], "r") as f: print(json.dumps(json.load(f)))' file.json

This then outputs it as the minified JSON string representation of the object above!

{"key": [124, 456], "key2": "value"}
