Every module is open from day one. No cohort, no unlock schedule.
about the courses
ChatGPT can write a formula in seconds, but only if you describe the sheet clearly, and only if you can tell when its answer is wrong. glostatsi teaches exactly that, one short module at a time.
There are six courses: Formulas & Functions, Data Cleaning & Prep, Pivots & Reporting, Dashboards & Charts, Power Query & Power Pivot, and VBA, Scripts & Macros. Every module pairs a short lesson with a practice workbook full of realistic, messy data, a prompt cheat-sheet and a finished file. All of it is open from day one, and the free ChatGPT tier is enough.
every module, the same four steps
learn
A short lesson explains the idea before you use it: what SUMIF checks, why XLOOKUP needs a match.
ask
Describe the columns and the result you need. The cheat-sheet has prompts you can copy and adapt.
practise
Try the formula on the practice workbook, with data as messy as the sheets at work.
compare
Open the finished version next to yours and go through it line by line.
left out on purpose
Short modules, real workbooks and prompts you can reuse. Some things are simply not part of it.
Certificates
No certificate or badge at the end. What you keep is the workbook you built and the patterns behind it.
Accreditation
The courses are not accredited and do not count towards a qualification.
Instructor access
No tutor or live help inside the courses. The finished file shows you what right looks like.
Unlock schedules
No cohort to wait for and no drip feed. Every module is open from the day your plan starts.
A paid ChatGPT plan
The free tier covers the lessons. The few advanced lessons that mention paid features say so.
