JSON Fixer

About JSON Fixer

JSON Fixer is a tool used to fix broken JSONs. I dealt with a lot of broken JSONs at times and wished a tool like this existed, so I created one for myself.

A lot of people use Large Language Models (LLMs) like ChatGPT, Claude, etc. to get JSON responses. These responses are at times broken. Each response has a chance of being broken in a different way, so a generic fixer might help.

When printing Python dicts, Python JSONs, Java stringifys, etc., they inadvertently add a lot of extra information to the JSON. This tool fixes the JSON created by them.

Frequently Asked Questions (FAQ)

Is my JSON broken? How can I tell?

There are a few ways to identify if your JSON is broken. It might not display correctly in a JSON viewer, or you might encounter errors when trying to parse it in your code. Online JSON validators can also help diagnose issues.

What types of JSON data can JSON Fixer handle?

JSON Fixer can handle most commonly formatted JSON data, including objects, arrays, strings, numbers, booleans, and null values.

Does JSON Fixer modify the original JSON data?

No, JSON Fixer works on a copy of your data. The original JSON remains unchanged.

What if JSON Fixer can't fix my JSON?

If JSON Fixer encounters an issue it can't handle, it will display an error message indicating the problem's location in the JSON data. You can then manually address the error or use a different JSON repair tool.

Are there any limitations to using JSON Fixer?

While JSON Fixer can address many common JSON issues, it's important to note it might not be able to fix severely corrupted data. Additionally, complex formatting issues might require manual intervention.
