Inhaltsangabe

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.
