What it is and what it does
json-with-comments is a Python library that extends JSON parsing to handle comments and trailing commas—features common in configuration files but not part of the JSON specification. It provides load/loads functions that strip single-line (//) and block (/* */) comments before parsing, and dump/dumps functions that can add comments and trailing commas when serializing.
The package has no external dependencies and supports Python 3.7 through 3.13 on both CPython and PyPy. Use it when you need to read or write JSON-like configuration files that include comments, or when working with JSONC format commonly found in configuration tools.
Use it for
- Parse configuration files in JSONC format that include comments and trailing commas.
- Strip comments from JSON during a preprocessing step before passing to strict JSON parsers.
- Serialize Python objects to JSON while preserving or adding explanatory comments for readability.
- Handle hand-edited JSON files that developers have annotated with trailing commas and comments.
