Description

---

You know exactly which spreadsheet I mean.
It's in a folder right now. Merged cells. Mystery columns. Dates that aren't really dates. Totals that don't add up. Forty rows of who-knows-what that someone emailed you, or that past-you built and never labeled. Every time you open it, your stomach drops a little - so you don't. You avoid it, and the dread just sits there.
This course is about opening it.And walking away with it fixed.
Here's the part that changes everything:you're not going to learn a wall of Excel formulas. No VLOOKUP lectures you'll forget by Friday. Instead, you'll hand the mess to Claude Cowork - an AI coworker - and describe, in plain English, what "fixed" looks like. It does the untangling: cleaning the data, straightening the structure, doing the math, and handing you back a spreadsheet you can actually trust.
Here's the rescue you'll learn
You'll start by turning dread into "I can just ask" - meeting Cowork and making your first real fix in a single sentence. Then you'll learn todiagnose a mess before touching it, so you never make it worse. You'llclean what's inside the cells - the text that won't behave, the numbers that are secretly text, the dates that aren't dates, the duplicates hiding in plain sight. You'llrestructure chaotic layouts into clean, sortable tables. You'll get theanswers the spreadsheet was always supposed to give you - totals, summaries, calculations - by describing them instead of writing them. And you'll make the fixlast , with a reusable cleanup checklist so the next scary spreadsheet isn't scary at all.
Bring your own spreadsheet. The one you've been avoiding. By the last lesson, you'll have run it through the whole process - diagnosed, cleaned, restructured, calculated, verified - and you'll have a fixed, trustworthy file you built yourself. Proof that the scary spreadsheet is now just. a spreadsheet.
No formulas. No jargon. No dread. Just a repeatable way to fix any mess a spreadsheet can throw at you - and the confidence to open the next one.
