The challenge

A business-critical workbook contains inconsistent dates, duplicate records, broken formulas, and values that look right but cannot be trusted.

01 / Approach
  1. Profile the workbook before changing it
  2. Trace formulas and standardize data types
  3. Separate safe corrections from human-review exceptions
  4. Deliver before-and-after QA evidence
02 / Deliverables
  • Cleaned workbook
  • Formula map
  • Duplicate controls
  • Exception queue
  • QA summary
  • Repeatable cleanup routine
