SheetsdrillAbout Sheetsdrill
Sheetsdrill is Google Sheets formula practice exercises with instant checking. It is one of the Dravari drill sites, a family of practice tools built on the same idea: the fastest way to learn a skill you use at a keyboard is to do it, on a live tool, with instant checking, until it is a reflex.
How the exercises work
Type the formula: Click a highlighted cell and type, as in Sheets: point at cells with the mouse or arrows, press Enter. The sheet calculates like the real thing. It reruns on changed data: Your formula is checked again with different inputs, so typed-in numbers and wrong references are caught. Learn from the feedback: Wrong value, a list that would spill, text instead of a number. Hints and a worked solution follow.
Every exercise is checked automatically against the expected result, not against a fixed answer string, so a correct approach passes even when it is written differently from the reference solution. If a check ever seems unfair there is a report link under it, and reports are read.
Who makes it
Sheetsdrill is made and operated by Dravari, LLC, a Delaware limited liability company based in Wilmington, Delaware, USA. The sites are built and maintained by a small team; there is no outside funding and no advertising on the practice pages. Revenue comes from Pro subscriptions, which is what keeps the free exercises free.
