<think>I see! Line 58 has `},` but line 59 has just `{` without a comma after `Animal Farm` on line 60. The issue is that my earlier fix added commas in wrong places. Let me look at the original lines more carefully - it seems like the original file has some issues.

Looking at the output:
- Line 58: `    },` - this is the end of an object with a comma
- Line 59: `    {` - start of new object
- Line 60: `      "title": "Animal Farm"` - missing comma after this!

So the issue is that line 60 ("Animal Farm") is missing a comma after it. Let me check the original file more carefully to understand the pattern of missing commas.

<think>Now I can see the specific issues - there are several places where a line ends with `"value"` and the next line starts a new field, but there's no comma. Let me write a script to fix these specific issues.

<think>I see - the issue is that my code is adding commas after lines that shouldn't have them (like after `pages": 376` which is the last field in the object). Let me be more careful about when to add commas.

The rule is:
1. Add comma after a value if the next line is another field in the same object
2. Don't add comma after the last field in an object (before `}`)
3. Add comma after `}` if followed by another object in an array

Let me rewrite the logic.

<think>The issue is that my code is adding commas in the wrong places. Let me take a different approach - let me manually create the fixed JSON by understanding the exact structure.

Looking at the original:
```
{
  "books": [
    {
      "title": "To Kill a Mockingbird",
      "author": "Harper Lee",
      "year": "1960",
      "genre": "Fiction",
      "pages": 376
    }   <-- Missing comma after this }
    {
      "title": "1984",
```

So the issue is that after `}` (end of object), there's no comma before the next `{`. But in some places the `}` already has a comma.

Let me look at the original more carefully to understand the pattern.
