I’ve found that the simplejson
module gives more descriptive errors in many cases where the built-in json
module is vague. For instance, for the case of having a comma after the last item in a list:
json.loads('[1,2,]')
....
ValueError: No JSON object could be decoded
which is not very descriptive. The same operation with simplejson
:
simplejson.loads('[1,2,]')
...
simplejson.decoder.JSONDecodeError: Expecting object: line 1 column 5 (char 5)
Much better! Likewise for other common errors like capitalizing True
.
