What they did
The writer downloaded their team’s marketing tracker as an XLS, uploaded it to Cowork and asked for a KPI dashboard on one screen with color-coding, targets and weekly trends. Cowork read every tab, picked the key metrics, asked for browser access, and created a new tab in the live Google Sheet.
How it went
The writer ended with one screen holding everything they needed, with status indicators, trend arrows and week-over-week comparisons. They watched it click around the spreadsheet for 20 minutes and estimate it would have taken them 4 - 6 hours.
Try it yourself with Claude Cowork
You are a data analyst. Build a KPI dashboard from the attached spreadsheet of [number] tabs, where each tab is one team member's data. Keep everything in one view, color-code status against targets, and show weekly trends so I can see at a glance if we are on track. Before you start, show me your plan. Put the dashboard in a new tab and do not change or delete any existing tab.
