{"name":"John","age":30,"city":"New York","skills":["JavaScript","Python","React"],"active":true}

Into this beautifully structured format:

```json
{
  "name": "John",
  "age": 30,
  "city": "New York",
  "skills": [
    "JavaScript",
    "Python",
    "React"
  ],
  "active": true
}

Much better, right?

Common JSON Errors and How to Fix Them

Even experienced developers make JSON mistakes. Here are the most common errors and their solutions:

Missing or Extra Commas

Error: Unexpected token

Problem:

{
  "name": "John"
  "age": 30
}

Solution: Add a comma after "John"

{
  "name": "John",
  "age": 30
}

Trailing Commas

Error: Unexpected token }

Problem:

{
  "name": "John",
  "age": 30,
}

Solution: Remove the comma after the last value

{
  "name": "John",
  "age": 30
}

Single Quotes Instead of Double Quotes

JSON requires double quotes. Always.

Problem:

{
  'name': 'John'
}

Solution:

{
  "name": "John"
}

Unquoted Keys

Problem:

{
  name: "John"
}

Solution:

{
  "name": "John"
}
