jsonlite - A simple, self-contained, serverless, zero-configuration, json document store.

•    Shell

JSONlite sandboxes the current working directory similar to SQLite. The JSONlite data directory is named jsonlite.data by default, and each json document is validated and saved pretty printed as a uuid. json_reformat is the fastest of the three. jq comes in at a close second and python -m json.tool is significantly the slowest. If possible, avoid using python -m json.tool.
