How to escape JSON with string parameters

Question

I try to send a POST request to my api using JSON, which has 2 parameters, both of which are string, but the 2nd parameter is a string consisting of an array. I use "", but the JSON can't be validated because it's wrong format. Example:

[
   {
      "command":"Light On",
      "electrodes_data":"[

How to escape JSON to convert 2nd parameter to string?

You have an error because it's a JSON specification, you can read answer of James Gentes:

JSON doesn't allow breaking lines for readability.
Are multi-line strings allowed in JSON?

A online testing tool: Jsonlint for example.

you have to remove the " around the array because you can't have multi-line in JSON:

I try to pass array as a string, because I don't want to use float in my api, this can break the precision of the data on the api side, how can I convert it to a string, is there any way to make it possible? — Elena, Dec 12 '21 at 23:21
so, can you convert each float to a string `"-1.676484279858414084e+00",` ? to have an array of strings — Jérôme Teisseire, Dec 12 '21 at 23:50
Well yes, I can convert it to a string. This is a good advise, but I have already decided to use float, and then I will create a mapper, which will convert it to a string. — Elena, Dec 13 '21 at 00:31
