Python CLI that profiles every column in an Excel file and flags hidden data-quality problems (mixed types, sentinel values, missing data, cardinality anomalies) in plain English. Outputs PDF, HTML, JSON, or annotated-Excel reports, with strict cell-level type detection that catches mixed-type columns pandas silently coerces.
Audits messy Excel workbooks for the data-quality issues that show up in real consulting engagements: mixed formats, misused fields, placeholder floods, and phantom duplicates. Generates HTML, Excel, and PDF reports.
