jwalk provides an easy way to inspect the object tree created by a JSON file via the command line.
The interface provided is a lot like a typical shell, with familiar commands like cd and ls.
More documentation (and fewer bugs) coming soon. In the meantime, install it via npm:
npm install -g jwalk
And then run it like this:
jwalk somefile.json
It can also handle gzipped files. If the extension is .gz, it will decompress the JSON data automatically.
jwalk somefile.json.gz
Bug reports and pull requests welcome!
