A JSON parser for Python that shows more useful error messages and fixes minor formatting errors automatically.
If you use JSON files a lot, it can get very frustrating to get an error just because you failed to delete a trailing comma, or to be forced to write unreadable multi-line strings without linebreaks, or to get error messages that don't tell you directly what is actually causing the error.
Since I needed to make this process as user-friendly as possible for my startup elody.com, I wrote this convenience library to make it easier.
- Supports Unicode (implicitly, since it just uses whatever string format python is using)
- Supports escape characters like normal JSON does.
- Supports extra commas
- Supports unquoted strings for several kinds of characters that can often occur in Rules and Options
- Supports linebreaks in quoted strings (they are treated the same as writing \n, except that any spaces and tabs following them are ignored.)
- Supports both ' and " as quotation marks
- Supports both null and None, so it works for parsing both Javascript and Python
- Supports True/true, False/false
- Does not support infinite or NaN numbers
- Has useful error messages
This works for Python 2.7 and 3+.
pip install loosejson
import loosejson
Just run loosejson.parse_loosely_defined_json(text) on a string. It returns a standard json object, just like json.loads(text), but with less of a headache.
