How to remove key data from all rows from json array using javascript

June 29, 2022

This is a JSON array. I want to remove the productID from all the rows.
when I console log I don’t want to see the productID in it.

"items": 
            [
                { 
                    "productID": "11234567",
                    "added": "TIMESTAMP",
                    "title": "Project",
                    "type": "Weekend Project",
                    "imageURL": "1"
                },

                { 
                    "productID": "11223456",
                    "added": "TIMESTAMP",
                    "title": "Bathroom",
                    "type": "Weekend Project",
                    "imageURL": "2"
                },

                { 
                    "productID": "11223345",
                    "added": "TIMESTAMP",
                    "title": "Curves",
                    "type": "Collections",
                    "imageURL": "3"
                }
            ]

The issue was I faced :

I needed to export the array in excel format. I got a simple function for it. but I have to remove some contents from the original JSON which is coming from the backend.

i checked lots of threads in StackOverflow but i cant find the correct solution.

>Solution :

assuming

const items =
            [
                { 
                    "productID": "11234567",
                    "added": "TIMESTAMP",
                    "title": "Project",
                    "type": "Weekend Project",
                    "imageURL": "1"
                },

                { 
                    "productID": "11223456",
                    "added": "TIMESTAMP",
                    "title": "Bathroom",
                    "type": "Weekend Project",
                    "imageURL": "2"
                },

                { 
                    "productID": "11223345",
                    "added": "TIMESTAMP",
                    "title": "Curves",
                    "type": "Collections",
                    "imageURL": "3"
                }
            ]

You can just iterate through all elements and delete id property:

items.forEach(o=>delete o.productID)

or map it into desired structure

const newItems = items.map((o)=>({"title":o.title,"added":o.added}))

Edit:

In first approach you don’t need to create new variable, you edit orginal one, in other one you get new object so you have to assign it to new variable.
