What BoringExcel is
BoringExcel is a small reference for people who want to understand Excel formulas, with a public article for each function and short lessons that build on one another.
How it is organised
The function articles can be read in any order and each follows the same seven parts, from a one-sentence definition to a common mistake. The lessons form an ordered path that starts with what a formula is and ends with combining INDEX and MATCH.
Practice, answers hidden
Every article ends its practice part with a prompt that uses different numbers than the worked example. The answer stays tucked inside a details element until you open it, so you can try the formula first.
Languages and access
BoringExcel is written in ten languages, and everything can be read without creating an account or signing in. Open a page, read it, and go back to your own spreadsheet.
