In this case, you can provide a third-party JSON parsing method. I recommend [JSON5](https://json5.org/), which is what is used in the [Demo](https://carlosnz.github.io/json-edit-react/) |

You can supply different formatting parameters to the native `JSON.stringify()`, or provide a third-party option, like the aforementioned JSON5.                                                                                           |
