jsonquotefixer 0.1.1

Fixer for broken/unescaped quotes in pseudo-JSON text

Json Fixer

Motivation

AI models often generate malformed JSON output due to incorrect handling of quotation marks.
A common issue is improperly nested double quotes, which makes the JSON invalid and unparseable with json.loads.
For example:

{
    "key1": "value1",
    "key2": "value2 is behind the "value1", that is good ",
}

The snippet above will raise a JSONDecodeError because of the invalid quoting.

Usage

jsonfixer automatically fixes broken quotation marks, allowing the JSON to be safely parsed with Python’s built-in json module.

Example usage:

import json
from jsonfixer import fix_quotes

a = <a malformed JSON-like string to be fixed>
json.loads(a)  # Raises JSONDecodeError!

b = fix_quotes(a)
json.loads(b)  # Successfully parsed

Arguments of fix_quotes

• s: a malformed JSON-like string to be fixed
• parse_code (bool, default=False): if True, extracts and fixes JSON from strings wrapped in triple backticks (```)
• replace_smart (bool, default=False): if True, replaces smart quotes (“ ”) with escaped straight quote (")
