Audit a CSV or JSON-array dataset (up to 5 MB, 50,000 rows, 200 columns and 2,000,000 cell
Audit a CSV or JSON-array dataset (up to 5 MB, 50,000 rows, 200 columns and 2,000,000 cells — rows x columns, the binding limit on wide data) and return a structured data-quality report as JSON: exact duplicate row count and up to 20 duplicate row indexes, per-column missing-value counts and percentages, inferred column types with a mixed-type flag, class-imbalance ratio for low-cardinality categorical columns, IQR-based outlier counts for numeric columns, PII-pattern hit counts (email/phone-like/SSN-like/credit-card-like) per column, and one overall quality_score (0-100, documented heuristic). Row content is never echoed back — only counts, percentages and indexes. Your data is held only in a temporary file for the duration of the request, deleted immediately after, and never logged or retained. PII-pattern hits (email/phone/SSN/credit-card-like) lower the quality_score but the matched values themselves are never returned. Do not submit data you are not authorized to process; this is a diagnostic tool, not a compliance or legal service. This is a triage heuristic for ML/data pipelines, not a certified data-quality or compliance audit.
