how to convert this string to object in javascript?

JSON need double quotes for strings. Single quote the outside, double quote the inside. — Mark, Jul 11 '18 at 18:59

JSON always needs to preceeded with single to double quotes, if you're parsing a String.

change your line to:

JSON.parse( '[{"dia": 1, "valor": "0,00"}, {"dia": 2, "valor": "0,00"}, {"dia": 3, "valor": "0,00"}]' );

PS: If you want to store your valor as a float, you should change its format from 0,00 to 0.00
