Reseña del libro "Before You Trust the Total: Clean Data, Check Changes, and Explain Your Results"

A tidy spreadsheet can still contain the wrong records. Before You Trust the Total is a practical guide for operations coordinators, small-business administrators, and spreadsheet users who need to explain how a result was produced. Follow an original order-export example through duplicate copies, legitimate returns, missing quantities, ambiguous dates, and joins that multiply amounts. Learn to preserve source records, state the rules for a change, keep unresolved data visible, and reconcile both the numbers and the records behind them. The book includes: A complete spreadsheet formula lab with expected results and deliberate failure tests. Eighteen diagnostic cases covering parsing, identifiers, missing matches, period boundaries, and misleading summaries. A worked replacement-snapshot case showing corrections, new records, and release comparisons. A method for evaluating AI-generated cleanup suggestions without accepting hidden assumptions. All business data is invented for teaching. The explanations and worked answers are included in the book; printing and external downloads are not required. Basic spreadsheet familiarity is enough to begin.
