Excel Data Cleaning, Formatting & Dashboard Reporting
This case study demonstrates an end-to-end Excel workflow applied to a generic business dataset covering raw data clean-up, structured formatting, formula-driven analysis, and an interactive dashboard for decision-ready reporting.
The problem
The raw dataset arrived with common but critical issues: inconsistent formatting, duplicate entries, mixed date formats, broken formulas, and columns that could not be reliably filtered or sorted.
What was done

5.Interactive dashboard
Outcome
The delivered workbook included a clean data sheet, an analysis tab with pivot tables and charts, and a page of interactive dashboard enabling the client to filter, explore, and report on their data independently.
