ReplaceAll to clean string

I have to clean my data using few replaceAll function.

JSON.parse(data.replaceAll('{\'', '{"').replaceAll('\'}', '"}').replaceAll('\',\'', '","').replaceAll('\': \'', '": "').replace(/[\n\r]+/g, ' ').replaceAll("  ", " "));

Is there a better way of doing this?

Any suggestions would be appreciated.

Thanks in advance

You could clean up the code and define your replacements in an array of pairs and iterate through it using reduce

const replacements = [["{'", '{"'], ["'}", '"}'], ["','", '","'], ["': '", '": "'], ['\n', ' '], ['\r', ' '], ['  ', ' ']];

const data = `{' {'{'{' {' '}'} '}'}  ','',' ',' ': ' ': '': '': '             Hello\n\r\n\n\r\n\n\r\nWorld\n\r`;

const newData = replacements.reduce((a, [token, replacement]) => a.replace(new RegExp(token, 'g'), replacement), data);

console.log(newData);

But as mentioned by Dean Taylor it's best to use a library to parse non-standard JSON data (if that is what you're trying to do).
