About Zeynep
I have trained office teams in spreadsheets for years, from people who are nervous about formulas to analysts who want to automate their weekly reports. I build tracking sheets, budgets and reporting workbooks, and I spend a lot of time fixing workbooks that grew without a plan.
I teach Excel and Google Sheets with a focus on habits that save time: clean tables, the modern lookup and dynamic array functions, PivotTables, and simple automation with Apps Script. I explain why a formula works, not just what to type.
Every course comes with practice files built from realistic office tasks, so you can use what you learn the next morning.

What students say
Jun H.
Sample Weekly report runs itself
Every Monday the managers get their summary and I do nothing. Worth far more than the price.
Leyla H.
Sample Power Query was a bonus
The short Power Query lesson automated my monthly export cleaning. Wish there was a full section on it.
Elif D.
Sample QUERY is a game changer
I replaced a whole sheet of helper columns with two QUERY formulas. The pivot lesson was excellent.
Patricia M.
Sample Tables changed everything
I never used Excel Tables before. Now my formulas are readable and my reports update when I add data.
Marco T.
Sample Apps Script without fear
I had never written code. Now our booking confirmations are sent automatically and marked as sent.
Kemal Y.
Sample XLOOKUP finally replaced VLOOKUP
Clear explanations and good practice files. The FILTER and UNIQUE lesson saved me hours every week.
Mina K.
Sample Reports look professional now
The charts and layout lessons improved how my manager sees my monthly report.
Hiba A.
Sample Great ARRAYFORMULA explanation
The header in the formula trick and multiplying conditions finally made array formulas work for me.
