Excel Data Analysis Spreadsheet

I need a polished Excel workbook that lets me explore, slice, and summarize my data quickly and accurately. The file should arrive ready for real-world use, not just as a template.

Scope
• Import and clean raw data (I’ll supply the source files).
• Build structured tables with clear headings and data validation where appropriate.
• Set up dynamic formulas, PivotTables, and slicers so I can drill down into trends without rewriting anything.
• Create at-a-glance visuals—think conditional-format heatmaps or concise charts—that update automatically when new rows are added.
• Document the logic in a brief “Read Me” sheet so anyone on my team can understand or tweak it later.

Tech preferences
I work in the latest Microsoft 365 environment, so feel free to leverage functions such as XLOOKUP, FILTER, and dynamic arrays, plus Power Query for heavier transformations. Basic VBA is fine if a step genuinely benefits from automation, but keep the code clean and commented.

What I’m looking for in your bid
Highlight similar data-analysis spreadsheets you’ve built and the specific Excel features you used. A short note on how you typically approach cleaning and summarizing data will help me gauge fit.

Deliverable
One fully functional Excel file (.xlsx) with all supporting queries, formulas, and visuals in place, ready for me to drop my data in and start exploring.
