# **About PracticeExcel**

On PracticeExcel you get better at Excel by using it. You work through short exercises in a real spreadsheet, type the formulas yourself, and see right away whether you got it right. Stuck? You can get a hint.

VLOOKUPSUMIF;

Every formula is checked, so the results match what Excel gives you, and the function and shortcut pages link straight to exercises on what you just read about.

## **Who's behind it?**

## **Nicolaj Gajhede**, founder of PracticeExcel

I'm a software developer, and I built PracticeExcel to help others get comfortable with Excel, and the best way to get there is to work through the formulas yourself.
