Project Summary
The client’s Excel-based sales table was presented as a static cumulative report with limited visibility into changes between periods. This restricted the ability to spot month-to-month fluctuations and made the reporting feel flat and manual.
What I Changed
Imported the raw sales tables into Tableau
Built a waterfall visualization to show contributions and declines over time
Applied color-coded highlights to distinguish positive vs. negative changes
Structured the dashboard with a cleaner layout and improved readability
Result
Transformed static tabular output into an interactive visualization
Allowed stakeholders to quickly identify periods of growth vs. decline
Delivered a professional presentation more suitable for decision-making
Published the final dashboard to Tableau Public for easy sharing
Tech Used
Tableau, Data Cleaning, Waterfall Visuals, Interactive Dashboards
