What is Formulo

Excel practice in a real spreadsheet, not videos to watch

Formulo is a website for practicing Excel: exercises in a real spreadsheet that check your formula instantly, with timed mock exams for job interviews and Excel skills tests. You write the formula with the real names, like VLOOKUP, IF or SUMIF, and the sheet tells you right away if it works.

An Excel skills test

Many employers send a timed Excel test before the interview. Formulo's mock exam is 10 exercises in 30 minutes, with no hints and a score at the end, so the clock is not a surprise. The questions are our own.

04Do I need Excel installed?
No. The spreadsheet runs in your browser, including on a work laptop where you can't install anything. The formulas you type are the same ones you'd type in Excel.
05I've never used Excel. Is it for me?
Yes. Topic 1 starts with what a cell is and how to write a formula. Every exercise has hints, and an explanation once you get it right.
06Will it help me pass an Excel test for a job?
It trains what those tests usually ask: VLOOKUP, IF, SUMIF, locking references and cleaning data. The mock exams copy the format: exercises in a sheet, a clock and no hints. The questions are ours, not from any employer.
07How does Formulo check my formula?
It runs your formula on your data and then on other data it changes behind the scenes. A formula that only works because you typed the answer by hand fails the second check.
08Is Formulo made by or affiliated with Microsoft?
No. Formulo is an independent website. Excel is a trademark of Microsoft Corporation.
09How much time do I need each day?
15 minutes is enough. Each exercise takes 2 to 5 minutes and your progress is saved, so you can stop halfway.
10What happens to my progress if I don't sign up?
It's saved in this browser. If you create a free account, it's saved to your account and you have it on any computer.
11My Excel is in another language. Does it still work?
Formulo's sheet uses English function names and commas, like English Excel. If your Excel is in Spanish, use the Spanish version of Formulo, or the formula translator on this page.
