Excel Age Line Chart

I want to end up with a clean, well-formatted Excel workbook that contains a line chart visualizing age groups by category. Right now I don’t have the underlying figures, so I also need you to source or compile a sensible dataset before building the chart.

Here’s what I expect:
• Gather or research the age-grouped data that matches my categories (I’ll share the categories once we start).
• Organize the figures in a clear table inside Excel.
• Create a line chart linked to that table, with useful labels, a readable axis, and light formatting that fits a corporate slide deck.
• Hand over the .xlsx file with the data table, the chart, and a short note explaining any sources or assumptions.

If you have experience cleaning datasets, working with Excel functions, and producing presentation-ready charts, I’d like to hear how you would approach this.
