Sales Data Analysis in Excel

I have a set of raw sales figures that needs to be explored, cleaned, and summarized directly in Microsoft Excel. The goal is to turn the numbers into clear, actionable insights that I can share with my team.

Here is what I need:
• A well-structured Excel file with the data properly formatted, de-duplicated, and error-checked.
• Pivot tables or other dynamic summaries highlighting overall performance, product or regional breakdowns, and any notable patterns you uncover.
• Visual aids—charts or graphs—embedded in the workbook so trends can be grasped at a glance.
• A short explanatory sheet (or note section) inside the file that points out the key findings and how to read the outputs.

Acceptance criteria
• All calculations must update automatically when underlying data changes.
• No external add-ins—everything should run in standard Excel.
• Workbook must be laid out clearly with labels and cell protections where appropriate.

If you regularly handle sales data analysis in Excel and can deliver a tidy, easy-to-follow workbook, you’ll be a great fit for this task.
