Text fille help

I have a text file created by another program (it's a json file)
I need to find a way to allow a user to delete an entry from the text file via a user interface.

Can anyone point me in the right direction. The issue I'm having is how to locate the specific entry and remove it.

Here is what the file looks like:

Code: Select all


{
    "items": [
        {
            "name": "color 1",
            "image": "",
            "day": "1",
            "month": "4",
            "year": "2020",
            "time": "",
            "duration": "1",
            "color": "1",
            "location": "",
            "description": ""
        },
        {
            "name": "color 2",
            "image": "",
            "day": "2",
            "month": "4",
            "year": "2020",
            "time": "",
            "duration": "1",
            "color": "2",
            "location": "",
            "description": ""
        },
        {
            "name": "color 3",
            "image": "",
            "day": "3",

Sorry, I should have provided more info....
(never worked with json or hash before so please forgive any dumb questions)

I am reading a json file into a text var (cText) and working with the data in the background.
I'm not displaying the data in a browse.
