According to the specification in the example on the picture: [ { "user_age": "21", "tags": ["cars","games"] } ] - The key name should be "userAge", not "user_age" - The format cannot start with "[]" - Numbers should be written without quotes: 21, not "21" - In the "tags" array, the listed values should be wrapped in "{}" objects

According to the specification, the corrected format should look like this:

• Keys in camelCase: userAge instead of user_age
• The format should be an object, not an array at the top level
• Numbers without quotes
• In the tags array, elements are objects, not strings

Example of correct JSON:

{
  "userAge": 21,
  "tags": [
    {"tag": "cars"},
    {"tag": "games"}
  ]
}

If multiple such objects are needed, they can be in an array:

[
  {
    "userAge": 21,
    "tags": [
      {"tag": "cars"},
      {"tag": "games"}
    ]
  }
]

This way, all the specification requirements are met.
