Use JSON.parse().

let collectionDataJSON = JSON.parse(collectionData);

console.log(collectionDataJSON.product_name);

You can use lodash library for your util methods,

npm i lodash

After installation:

import _ from 'lodash';

const productName = _.get(collectionData, 'product_name', 'default_name')

console.log(productName);
