Here’s what you’ll need and what you’ll make. You can return to this guide during any lesson.
For the eight-week program, use the weekly project checklist. Larger course examples are optional extensions.
- Download the practice workbook and preserve an untouched original copy.
- Choose a small, non-sensitive dataset with a known business question.
- Write definitions for each field, unit, date, status, and missing value.
- Decide who will use the finished file and what they need to decide from it.
Finish with proof you can use.
An auditable workbook with a clean source-data table, documented calculations, controlled inputs, a refreshable pivot analysis, a decision-focused dashboard, validation checks, instructions, and a read-only handoff copy.

- A tidy source table with data dictionary, validation rules, and refresh timestamp.
- The six-order calculation sheet, paid category totals, and a note showing your changed-quantity test.
- The two source lists, cleaned status and pickup helper columns, match counts, and a note explaining how the missing pickup was resolved.
- Two pivot summaries (paid sales by category and all order values by status), plus a note explaining the canceled-order test.
- A one-screen dashboard with no more than six key views and a definitions panel.
- An audited workbook plus a five-minute handoff guide another person can follow.
Three ideas to help you along the way
The rules behind the steps.
One row, one record
Rectangular source data with stable headers and consistent types makes formulas, pivots, filters, and imports dependable.
Separate input, logic, and output
Raw data, calculations, assumptions, and presentation should not be mixed so heavily that changes become dangerous.
Auditability beats cleverness
A colleague should be able to trace a result, identify assumptions, and refresh it without relying on your memory.
What do these words mean?
Key terms worth knowing.
- Record
- One complete entity or event represented by a row in a well-structured table.
- Absolute reference
- A cell reference such as $B$2 that remains fixed when a formula is copied.
- Lookup key
- A stable field used to match records across tables, ideally unique where required.
- Pivot table
- An interactive summary that groups and aggregates records without changing source rows.
- Reconciliation
- A check that totals, counts, or records agree with a trusted source or expected control.
