Answer 1

This is not an endorsement of bad object serialization

If you absolutely must consume the data in this format, you can replace the single quotes with double quotes to make them JSON-compliant:

 const data = [ { "Name": "Martine of Martine's Table", "City": "Amsterdam", "Cuisine_Style": "['French', 'Dutch', 'European']", "Ranking": 1, "Rating": 5, "Number of Reviews": 136 }, { "Name": "De Silveren Spiegel", "City": "Amsterdam", "Cuisine_Style": "['Dutch', 'European', 'Vegetarian Friendly', 'Gluten Free Options']", "Ranking": 2, "Rating": 4.5, "Number of Reviews": 812 } ]; for (const item of data) item['Cuisine_Style'] = JSON.parse(item['Cuisine_Style'].replace(/'/g, '"')); console.log(data);

Answer 2

Try this.

 var arr_data = [{ "Name": "Martine of Martine's Table", "City": "Amsterdam", "Cuisine_Style": "['French', 'Dutch', 'European']", "Ranking": 1, "Rating": 5, "Number of Reviews": 136 }, { "Name": "De Silveren Spiegel", "City": "Amsterdam", "Cuisine_Style": "['Dutch', 'European', 'Vegetarian Friendly', 'Gluten Free Options']", "Ranking": 2, "Rating": 4.5, "Number of Reviews": 812 } ]; var y = JSON.stringify(arr_data); var x = y.toString(); console.log(x);
