Summarizes JSON file contents (or native Python data structures)
Pretty easy to run in Python 2.X (tested on Python 2.7):
python summarize_json.py <JSON file>
This script prints out a summary of your JSON file's contents, essentially inferring a schema using some simple heuristics.
It comes in handy for understanding the structure of a blob of JSON (or native Python) data that someone else hands to you without proper documentation. And it can also be used to manually sanity-check files for outliers, weird values, inconsistencies, etc.
