jsonchecker

Checks a JSON file for any duplicate keys, which would be ignored by the normal parser.

Inspired by and based off of a python-list mailing list post: <https://mail.python.org/pipermail/python-list/2013-May/660874.html>.

Dependencies:

• Python 2.7 or Python 3

Installation:

• pip install jsonchecker

Or:

• git clone https://github.com/legoktm/jsonchecker.git && cd jsonchecker && python setup.py install

Usage:

• jsonchecker file_to_validate.json
• jsonchecker directory/of/json/files/

An optional --quiet argument can be passed, and will cause the script to print out a . instead of the full filename for each file scanned. Useful if you plan on checking a large number of files.

The script will exit with a status code of 1 if any duplicate keys are found, 0 if none are.

An optional --values argument can be passed to additionally check for duplicate values within each key. The script will exit with a status code of 1 if there are either duplicate keys or duplicate values are found, 0 if none are.
