## Overview

X12 Utils is a small Python library with two independent utilities: a generator that turns segment-and-element lists into EDI text, and a validator that wraps pyx12 and returns validation status and optional outputs. The README documents both workflows; the validator source shows its pyx12 call and captured results. The generator excerpt does not use its output_file or sub_element_separator parameters, so they are not represented as capabilities.

Main entry points: [`x12_utils/x12_validator.py`](https://github.com/willingham/x12-utils/blob/master/x12_utils/x12_validator.py) (EDI validator), [`x12_utils/x12_generator.py`](https://github.com/willingham/x12-utils/blob/master/x12_utils/x12_generator.py) (EDI generator)
