This spreadsheet contains 300 rows of inventory data across two sheets — one with item entries (ID, product, category, quantity, price) and calculated totals, another summarizing values by category using SUMIF/COUNTIF formulas. It demonstrates accurate large-scale data entry, consistent formatting, and working knowledge of Excel formulas for automatic totals and category breakdowns. All numbers recalculate automatically if inputs change, showing the file isn't just static typed data. This kind of structured, formula-driven work reflects what a client would expect from a professional data entry service.
