How to restructure JSON output for backend compatibility?

Backend
1

I’m stuck with a JSON formatting issue. My form produces output like this:

{
  "userInfo": {
    "name": null,
    "age": null,
    "email": null,
    "phone": null
  },
  "preferences": {
    "color": null,
    "size": null
  },
  "userId": "abc123",
  "lastLogin": "2023-05-01"
}

But I need to change it to this format for my backend:

{
  "userInfo": [
    {
      "name": null,
      "age": null,
      "email": null,
      "phone": null
    }
  ],
  "preferences": [
    {
      "color": null,
      "size": null
    }
  ],
  "userId": "abc123",
  "lastLogin": "2023-05-01"
}

How can I add the square brackets to make certain objects into arrays? Any help would be great!

To restructure your JSON output, you can utilize a recursive function in your preferred programming language. This approach allows for a more flexible solution that can handle nested objects of varying depths. Here’s a general algorithm:

  1. Create a function that takes an object as input.
  2. Iterate through each key-value pair in the object.
  3. If the value is an object (but not an array), wrap it in an array.
  4. If the value is an object or array, recursively apply the function to it.
  5. Return the modified object.

This method ensures that all non-array objects at any level are converted to single-element arrays, maintaining the structure you need for backend compatibility. It’s a robust solution that can adapt to potential changes in your JSON structure in the future.

hey mate, you can use javascript to do this easily. just wrap the objects in arrays like this:

jsonData.userInfo = [jsonData.userInfo];
jsonData.preferences = [jsonData.preferences];

that should do the trick! let me know if u need more help

hey there! have u considered using a JSON parsing library? they often have built-in methods for restructuring data. what language r u working with? maybe we could explore some cool libraries together that coud make this task super easy. whats ur experience with JSON manipulation so far?
