Your EastMallBuy order history spreadsheet is a goldmine of information, but raw data alone can be overwhelming. By visualizing this data, you can track performance over time, identify trends, and make more informed purchasing decisions. This guide will show you how to create powerful charts for three key metrics: Delivery Speed, Refund Rates, and QC (Quality Control) Consistency.
