SheetQuest
Practice practical spreadsheet tasks with actual cells and a bounded formula engine. Calculate cafe revenue, stock decisions, discounts, margins, remaining budgets and delay summaries, then test your target formulas across changed inputs.
How we build a check
This workbench processes supported inputs locally. We test calculations, file structure and generated artifacts using independent readers or known fixtures where available. The example runs the same processing path as a supplied input; it does not stand in for checking your own result.
