Parse Javascript Object to JSON-like string, but with single quotes

Question

This is my Javascript object that I converted into a string (JSON)

 var myObj = { name: 'John', age: 25, group: 'O+' } console.log(JSON.stringify(myObj));

I need the output with single quotes (apostrophes) (') and not double quotes ("). Also no quotes or apostrophes on the indexes/keys. I want it to look like this:

{name:'John',age:25,group:'O+'}

I tried this:

 var myObj = { name: 'John', age: 25, group: 'O+' } console.log(JSON.stringify(myObj).replace(/"([^"]+)":/g, '$1:'));

This removes the quotes on the indexes/keys but the values still have quotes in them. Need to replace them with apostrophes. Tried some more regexes but they did not work.

Answer 1

If you add some more replaces at the end of that stringify, you can actually get what you want. Here is your example:

 var myObj = { name: 'John', age: 25, group: 'O+' } console.log(JSON.stringify(myObj).replace(/"([^"]+)":/g, '$1:').replace(/\\\\"/g, '"') .replace(/([\\{|:|,])(?:[\\s]*)(")/g, "$1'") .replace(/(?:[\\s]*)(?:")([\\}|,|:])/g, "'$1") .replace(/([^\\{|:|,])(?:')([^\\}|,|:])/g, "$1\\\\'$2"));

You can find this exact example on a different forum on stackexchange. Here is the link .

You can use JSON.parse reviver to format the values like this.

 var myObj = { name: 'John', age: 25, group: 'O+', bool:true, hello:{ a:'bb' } } const reviver =(key, value)=>{ if(typeof value === 'string'){ return `'${value}'` } return value } var a = JSON.parse(JSON.stringify(myObj), reviver); console.log(JSON.stringify(a).replace(/"/g,''));
