That's not a valid json string. You can play around with replace but it's better to fix how that json is generated. Every language has a method to convert an object json string. — adiga

This should do the trick:

var str = '{ "name"="John", "age"=30, "car"=null }';
str = str.replace(/=/g,":");

var json = JSON.parse(str);

Note, that it would convert ALL "=" to ":". If there can be symbol in name or value, different approach should be used.

-- Update "g" modifier has to be used if there is more than one "=" to replace.

Use g flag:

'{ "name"="John", "age"=30, "car"=null }'.replace(/\=/g, ':')

You can use Replace

let op = `{ "name"="John", "age"=30, "car"=null }`.replace(/=/g, ':')

console.log(op)
