Excel Data Analysis Assistance

I have an existing Excel workbook that I need analyzed so I can quickly extract meaningful insights from the raw numbers. Everything is already in .xlsx format, so there is no importing or data-cleaning from other sources—just solid, thoughtful analysis inside Excel itself.

Your task will be to open the file, explore the data, and apply appropriate analytical techniques so the key trends, relationships, and outliers become clear. I’m open to whatever native Excel tools you feel are best for the job—PivotTables, formulas, dynamic arrays, conditional formatting, or even Power Query if that speeds things up—so long as the final result is easy for me to follow and update.

Deliverables I’m expecting:
• An updated copy of the workbook with your analysis fully embedded
• A brief, plain-language summary (inside a separate sheet or a short document) explaining what you did and the main findings

Please keep all work contained within the original file structure and name any new sheets clearly so I can navigate them quickly.
