Everyday Excel
Stop wrestling with unruly spreadsheets. Learn how to write reliable formulas, fix common calculation blunders, and turn raw lists into clean, actionable summaries.
Like Duolingo, but for Everyday Excel. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Making Numbers Work for You and Organizing, Filtering, and Summarizing. It starts from scratch.

Key ideas in Everyday Excel
- Typing letters or units inside a cell turns the whole entry into text
- Excel cannot perform math on text entries
- Put raw numbers in the data cells and label the unit in the column header instead
- Excel treats any input without a leading '=' as literal plain text
- An equals sign tells Excel to calculate the expression rather than just display the characters
- Excel dynamically stretches range references when rows are inserted within the range boundaries
- The formula updates automatically to =SUM(B2:B11) and includes the new value in the total
- Manual addition formulas like =B2+B3+B4 do not include newly inserted rows
- The small green square in the bottom-right corner of a selected cell is the fill handle
- Double-clicking the fill handle sends the formula all the way down to the bottom of the neighboring list
- Double-clicking a column boundary auto-expands the width
- A string of '###' symbols means the column is simply too narrow to show the full number
- Hashtags do not indicate a math error or broken formula
- Widen the column by dragging its header border or double-clicking it to reveal the number
- Excel changes row numbers automatically when copying formulas down a column
- Relative references maintain their spatial relationship to nearby neighbor cells
