Original: Stop Writing .isnull() — Audit Your Dataset in One Line with OMR
Short summary
OMR (Omni Data Refinement) is an open-source Python library that replaces boilerplate data-quality checks with a single health() call, producing a 0-100 score across completeness, uniqueness, consistency, validity, and conformity. It also offers auto-cleaning with transformation logs, schema validation, drift detection using PSI/KS/JS divergence, and column profiling for all data types. The library requires only pandas, numpy, and rich — no cloud or LLM dependencies.
- •OMR provides a 0-100 dataset health score across 5 quality dimensions in one call
- •Includes auto-cleaning, schema validation, drift detection, and full-column profiling
- •Open-source Python library with no cloud or LLM dependencies
