Every row has a reason.
Refresh the sample. Follow each exclusion. See the numbers reconcile.
All records are fictional. USD amounts exclude tax and other accounting adjustments. This demonstrates reconciliation and refresh, not accounting assurance. Read the data dictionary and refresh guide.
Take the working workbook with you ↓ Open the synthetic sample in a spreadsheet app, change the inputs and follow the checks. The workbook has room for 200 input rows.
Situation
A weekly report contains duplicates and incomplete rows.
What changes
You change the input and see a local calculation or state update. Nothing is sent to an external service.
How it is checked
Both sample inputs reconcile against known row counts and completed totals.
What remains limited
The data and scenarios are synthetic. This is inspectable sample work, not evidence of a client outcome.

A rough idea is a perfectly good place to begin.
