My main goal is to loop through this and return a new object containing items that have at least one digit so in the end i will have something similar to this example. The new object should be a new JSON file:

{
        "key": "ASDV1-01.jpg",
        "data": {
            "documentid": "CE44DBAC-59B2-4178-8392-0141FB2F58DF",
            "scandate": "Feb  1 2018 12:05PM",
            "F08": "1",
            "F10": "101076",
        }
    }

Of course, this should be applied for the whole object. Tried to do this with regex syntax but with no use. Thank you in advance

By digit you mean like 0 or a? (then it would be a character) you can loop trough the whole Json and check for each key if the corresponding value is len() >= 1 if it is, then add it to a new Object. You can also use a filter like in this example (example for getting all odd numbers):

const odd = x => x % 2 === 1;

[1, 2, 3].filter(x => x % 2 === 1);

Have a look here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter

loop through whole array of images and test() key if it contains any digit with /\d/ regex

let data = [
    { "key": "no-digit.jpg" },
    { "key": "has2-digits7.jpg" },
    { "key": "again-no-digit.jpg" }
];

data = data.filter(item => /\d/.test(item.key));

console.log(data);
