JSON Flatten and Unflatten Utilities

json-flatten is a Python library providing functions to convert a nested JSON object into a single-level dictionary of key-value pairs, and to reconstruct the original JSON object from that flattened representation. It's particularly useful for scenarios like converting JSON for HTML forms or query string parameters. The library is actively maintained, with releases typically addressing bug fixes and minor enhancements. The latest version is 0.3.1.
