Need help to convert below JSON string into JSON object.Even string JSON is valid json (verified by /).

JSON:

{
    "condition": "AND",
    "rules": [{
            "id": "amount",
            "operator": "greater_or_equal",
            "value": "900"
        },
        {
            "condition": "AND",
            "rules": [{
                    "id": "vendorname",
                    "operator": "equal",
                    "value": "US BANK NATIONAL ASSOCIATION"
                },

                {
                    "id": "vendorname",
                    "operator": "equal",
                    "value": "HANSEN SOLUTIONS  LLC"
                }
            ]
        }
    ]

}

Your JSON string is multiline. Multiline string should be stored using template literals, otherwise use string concatenation to represent your string.

The below exmaple uses template literals. It is used to represent multi line string.

var str = `{
	"condition": "AND",
	"rules": [{
			"id": "amount",
			"operator": "greater_or_equal",
			"value": "900"
		},
		{
			"condition": "AND",
			"rules": [{
					"id": "vendorname",
					"operator": "equal",
					"value": "US BANK NATIONAL ASSOCIATION"
				},

				{
					"id": "vendorname",
					"operator": "equal",
					"value": "HANSEN SOLUTIONS  LLC"
				}
			]
		}
	]
}`;

console.log(JSON.parse(str));

This is a single line string.

var str = '{"condition":"AND","rules":[{"id":"amount","operator":"greater_or_equal","value":"900"},{"condition":"AND","rules":[{"id":"vendorname","operator":"equal","value":"US BANK NATIONAL ASSOCIATION"},{"id":"vendorname","operator":"equal","value":"HANSEN SOLUTIONS  LLC"}]}]}';

console.log(JSON.parse(str));

Need help to convert below JSON string into JSON object.Even string JSON is valid json (verified by https://jsonlint./).

JSON.parse(jsonString); Is a pure JavaScript approach so long as you can require a reasonably modern browser.

See also https://developer.mozilla/en/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse

Update: Try JSON.parse(JSON.stringify(TheString))

Just using

try {
      let obj = JSON.parse( string);
} catch( e) {
    // conversion fails
   console.error( e ) 
}
