4 sections · 8 lessons
Define where AI fits in spreadsheet cleaning, lock the cleaning rules, and establish verification and documentation standards before any automation runs.
2 lessonsTrace silent cleaning errors, then build a data-quality profile and cleaning plan tied to business rules without changing the data yet.
2 lessonsGenerate auditable automation in Excel and Google Sheets, then verify outputs against expectations so the cleaning steps remain reproducible.
2 lessonsRun a verification suite, diagnose and correct cleaning failures, then deliver the cleaned extract with a defensible change log and handoff notes.

Spreadsheet cleaning with AI is useful only when every transformation is traceable, tested, and defensible. This course shows how to combine AI with workbook rules, data-quality checks, and documented decisions so cleaning work in Excel and Google Sheets stays reproducible instead of mysterious. Learners leave with a practical workflow for profiling data, generating automation, catching silent failures, and handing off cleaned files with a change log.
The course covers workflow design for AI-assisted cleaning, decisions about missingness, duplicates, types, and outliers, and methods for spotting silent failures such as coercion and row drops. It also covers data-quality profiling, reproducible automation in Excel and Google Sheets, verification, debugging, and final delivery with documentation.
From project managers and operators to founders, analysts, and teams adopting AI, Fenzo is for people who want to get better at the work they already do.
Anything from using AI for project planning and analysis to improving workflows, decision-making, communication, and delivery. If you can describe the skill or task, Fenzo can build a course around it.
Yes. Tell Fenzo what you do, what you’re trying to accomplish, and where you’re stuck, and Fenzo will shape the course around your role, your goals, and the work you actually have to do.
No. Fenzo adapts to your starting point, so you can begin with the fundamentals or jump straight into more advanced work.
Yes. Fenzo for Business puts the whole team on one plan — shared seats, courses you can assign, and reporting on who has finished what.

What the science says
Offloading thinking to AI erodes the very skills you’re trying to build.
How Fenzo does it
Fenzo makes you do the thinking — guided, but never done for you.
