Excel Data Cleanup & Insights

I have an existing Excel workbook that needs a thorough refresh. The data must be cleaned and reorganised so every column is consistent and free of duplicates, after which the numbers should run automatically through accurate formulas and calculations I will outline. Once the figures are reliable, I also want clear charts and graphs that turn those results into quick-to-read visual insights.

You will work directly in my current file, preserving the original structure where it makes sense and introducing new sheets or pivot tables only when necessary. The finished spreadsheet should:

• Load without errors or broken links
• Contain tidy, validated data with no stray formatting
• Perform the requested calculations via formulas, not manual typing
• Display at-a-glance visuals (bar, line, or pie charts—whichever best suits each dataset)

Please share a brief note on similar Excel clean-ups you have handled and your typical turnaround time. I will send the workbook and a short spec as soon as we agree to proceed, and I’m happy to answer any clarifying questions along the way.
