Remove item from JSON list

[Amy V2]

I'm trying to remove a specific item from a JSON list. Below is a generic example of a JSON list that gets created from an OOTB business rule when a user changes the variables on a form they submitted.

[{"questionLabel":"Item to Remove","questionCurrValue":"new variable value","questionPrevValue":"previous variable value"},{"questionLabel":"Second item in list","questionCurrValue":"Yes","questionPrevValue":"No"},{"questionLabel":"Third item in list","questionCurrValue":"second test","questionPrevValue":"first test"},{"questionLabel":"Hidden item in list","questionCurrValue":"NA","questionPrevValue":""}]

What I'd like to do is search for the question labeled Item to Remove, and remove that whole item from the list, so the resulting list would be:

[{"questionLabel":"Item to Remove","questionCurrValue":"new variable value","questionPrevValue":"previous variable value"},{"questionLabel":"Second item in list","questionCurrValue":"Yes","questionPrevValue":"No"},{"questionLabel":"Third item in list","questionCurrValue":"second test","questionPrevValue":"first test"},{"questionLabel":"Hidden item in list","questionCurrValue":"NA","questionPrevValue":""}]

Any help is appreciated. Thanks!

try this

// Your original JSON array as a string
var jsonString = '[{"questionLabel":"Item to Remove","questionCurrValue":"new variable value","questionPrevValue":"previous variable value"},{"questionLabel":"Second item in list","questionCurrValue":"Yes","questionPrevValue":"No"},{"questionLabel":"Third item in list","questionCurrValue":"second test","questionPrevValue":"first test"},{"questionLabel":"Hidden item in list","questionCurrValue":"NA","questionPrevValue":""}]';

// Parse the string to a JS array
var jsonArray = JSON.parse(jsonString);

// The label you want to remove
var labelToRemove = "Item to Remove";

// Filter out the item(s) with that label
var filteredArray = jsonArray.filter(function(item) {
    return item.questionLabel !== labelToRemove;
});

// Convert back to JSON string if needed
var resultString = JSON.stringify(filteredArray);

// Output (for testing)
gs.info(resultString);
