Install

Install Serieux with pip install or uv add:

pip install serieux

File format support

Serieux natively supports loading and dumping data from/to JSON files and loading from TOML files. For YAML support, install pyyaml:

pip install pyyaml

Note that for the time being, YAML is the only filetype for which Serieux implements location tracking and patching. Loading data as YAML will therefore enable better errors (note that JSON is valid YAML).

For faster JSON processing, I recommend installing msgspec. Here's a list of all packages recognized by Serieux:

• JSON: msgspec, orjson, ujson (built-in json module as a last resort)
• YAML: pyyaml
• TOML: toml, tomli, tomli-w (for writing) (built-in tomllib as a last resort)
