Answer 1

Hold on, so initially you've done JSON.parse('{ "product_name": [ "Harpic Power Plus Original Liquid Toilet Cleaner", "HARPIC Powerplus Disinfectant Toilet Cleaner, Original - 1L Liquid Toilet Cleaner"]}'); and got an array? That's a JS array, not a JSON array. You can access its values using the array keys, eg const foo = JSON.parse('{ "product_name": [ "Harpic Power Plus Original Liquid Toilet Cleaner", "HARPIC Powerplus Disinfectant Toilet Cleaner, Original - 1L Liquid Toilet Cleaner"]}'); console.log(foo.product_name[0]); console.log(foo.product_name[1]); const foo = JSON.parse('{ "product_name": [ "Harpic Power Plus Original Liquid Toilet Cleaner", "HARPIC Powerplus Disinfectant Toilet Cleaner, Original - 1L Liquid Toilet Cleaner"]}'); console.log(foo.product_name[0]); console.log(foo.product_name[1]); hope this works

Answer 2

a json formatted of your sample would be like this:

 var myJson = { first: "Harpic Power Plus Original Liquid Toilet Cleaner", second: "HARPIC Powerplus Disinfectant Toilet Cleaner, Original - 1L Liquid Toilet Cleaner" }; console.log(JSON.stringify(myJson));
