Can I Trust This Data?

From three raw agricultural spreadsheets to a finding you can defend: profile the tables, find the duplicates, gaps, wrong and inconsistent values, check them against business rules and a master list, log every issue, clean them in views without touching the originals, join tables recorded at different grains, measure change, and write it up so a colleague can rerun it. One brief, one notebook for the whole book, seventeen tasks: one per chapter of the book Can I Trust This Data?, each with an automatic check. Everything runs in the browser. Views you create are gone after a page reload until you press Run all, so after reopening the project press Run all before running anything else.
