# json_repair
Repair malformed JSON from LLMs, APIs, logs, and user input in Python.
- Fix missing quotes, commas, brackets, comments, stray prose, and truncated values.
- Use it as a drop-in fallback for `json.loads()` or as a schema-guided repair step.
- Install with `pip install json-repair` or try the [live demo](https://mangiucugna.github.io/json_repair/).
---
## Quick example
```python
import json_repair
bad_json = '{"users":[{"name":"Ada","role":"admin",}],"ok":true'
decoded_object = json_repair.loads(bad_json)
# {'users': [{'name': 'Ada', 'role': 'admin'}], 'ok': True}
```
If `json_repair` saves you time, [star the repository](https://github.com/mangiucugna/json_repair) so more people can find it.

# Motivation
Some LLMs are a bit iffy when it comes to returning well formed JSON data, sometimes they skip a parentheses and sometimes they add some words in it, because that's what an LLM does.
Luckily, the mistakes LLMs make are simple enough to be fixed without destroying the content.
I searched for a lightweight python package that was able to reliably fix this problem but couldn't find any.
*So I wrote one*
# Supported use cases
### Fixing Syntax Errors in JSON
- Missing quotes, misplaced commas, unescaped characters, and incomplete key-value pairs.
- Missing quotation marks, improperly formatted values (true, false, null), and repairs corrupted key-value structures.
- Python-style tuples: comma-separated parenthesized sequences become JSON arrays, while a single parenthesized value remains a scalar. Within arrays, objects, and tuples, `true`/`false`/`null` and `None` are recognized case-insensitively as JSON booleans or null.
### Repairing Malformed JSON Arrays and Objects
- Incomplete or broken arrays/objects by adding necessary elements (e.g., commas, brackets) or default values (null, "").
- The library can process JSON that includes extra non-JSON characters like comments or improperly placed characters, cleaning them up while maintaining valid structure.
### Auto-Completion for Missing JSON Values
- Automatically completes missing values in JSON fields with reasonable defaults (like empty strings or null), ensuring validity.
# How to use
Install the library with pip
pip install json-repair
then you can use use it in your code like this
from json_repair import repair_json
good_json_string = repair_json(bad_json_string)
# If the string was suExcerpt of 19,514 characters
