Interactive Sales Dashboard Builder

I have regular Excel and CSV exports of our order history and I need them transformed into a single, interactive dashboard focused on tracking sales and revenue. The view must let me drill into performance by product, category, and individual customer, compare periods, and spot trends at a glance. Data source • All numbers come from the Excel/CSV files I will provide. A simple, reliable refresh workflow—drag-and-drop upload or an automated watched-folder setup—needs to be in place so I’m not manually rebuilding the visuals every time. Core features • Clear top-level revenue KPIs with the ability to filter by date range • Drill-down charts that break sales out by product, category, and customer • Interactive filters and tooltips so anyone on the team can explore the data without touching the raw files • Clean, branded layout that I can share or export to PDF for weekly meetings Preferred stack I am open to common BI tools such as Power BI, Tableau, Looker Studio, or a lightweight web app (e.g., React + D3) as long as the final result is interactive, easy to maintain, and can read the Excel/CSV inputs. Deliverables 1. Fully functional dashboard file or hosted link 2. Source project with clear instructions for refreshing the data 3. Short loom or PDF walkthrough showing how to use the filters, drill-downs, and refresh process Once the above is in place and working smoothly, I’ll sign off. Looking forward to seeing how you would approach the build.
