The JSON standard requires double quotes and will not accept single quotes  nor will the parser   If you have a simple case with no escaped single quotes in your strings  which would normally be impossible  but this isn t JSON   you can simple str replace    g       and you should end up with valid JSON

If you are sure your JSON is safely under your control  not user input  then you can simply evaluate the JSON  Eval accepts all quote types as well as unquoted property names   var str      a  1    var myObject    0  eval        str           The extra parentheses are required due to how the eval parser works  Eval is not evil when it is used on data you have control over  For more on the difference between JSON parse and eval   see JSON parse vs  eval

Using single quotes for keys are not allowed in JSON  You need to use double quotes   For your use-case perhaps this would be the easiest solution   str      a  1      Source      If a property requires quotes  double quotes must be used  All   property names must be surrounded by double quotes
