How to remove space in keys of a JSON object (3 answers)

Closed 2 years ago.

I have my json in the below format

[{
    "Id": "ALFKI",
    "Contact Name": "Maria Anders",
    "Contact Title": "Sales Representative",
    "City": "Berlin",
    "Slider": 10
}, {
    "Id": "ANATR",
    "Contact Name": "Ana Trujillo",
    "Contact Title": "Owner",
    "City": "México D.F.",
    "Slider": 5
}]

My desired Json

[{
    "Id": "ALFKI",
    "ContactName": "Maria Anders",
    "ContactTitle": "Sales Representative",
    "City": "Berlin",
    "Slider": 10
}, {
    "Id": "ANATR",
    "ContactName": "Ana Trujillo",
    "ContactTitle": "Owner",
    "City": "México D.F.",
    "Slider": 5
}]

Kendo grid doesn't accept Key names with spaces

You can use JSON.stringify(), JSON.parse(), String.prototype.replace() with RegExp /\s(?=\w+":)/g to match space character followed by one or more word characters followed by " followed by :

var arr = [{
    "Id": "ALFKI",
    "Contact Name": "Maria Anders",
    "Contact Title": "Sales Representative",
    "City": "Berlin",
    "Slider": 10
}, {
    "Id": "ANATR",
    "Contact Name": "Ana Trujillo",
    "Contact Title": "Owner",
    "City": "México D.F.",
    "Slider": 5
}];

arr = JSON.parse(JSON.stringify(arr).replace(/\s(?=\w+":)/g, ""));

console.log(arr);
