Excel for Everyday Work
Transform messy rows of text into automated, clear answers. Learn to build self-calculating sheets, organize raw data cleanly, and summarize key numbers in minutes.
Like Duolingo, but for Excel for Everyday Work. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 10 levels across 2 sections, about 20 minutes end to end, roughly 4 days at five minutes a day. It moves through Building a Dynamic Sheet and Extracting Answers and Insights. It starts from scratch.

Key ideas in Excel for Everyday Work
- Starting a cell entry with an equals sign (=) tells Excel to treat what follows as a formula to calculate
- Entering math symbols without a leading equals sign causes Excel to store and display the entry as plain, static text
- Pressing Enter calculates and displays the resulting value while preserving the formula behind the scenes
- Referencing cell coordinates like A1 links the formula directly to that cell's current contents
- When an input cell changes, Excel recalculates all formulas depending on that cell immediately
- Typing raw numbers directly into a formula creates static math that cannot react to sheet updates
- Dragging the fill handle copies a formula down while automatically adjusting row numbers to match the new row
- Standard cell references without extra symbols are relative, meaning they point to cells relative to where the formula sits
- Moving down one row increments row numbers by one (A1 becomes A2, B1 becomes B2)
- Adding dollar signs ($) before a column letter or row number locks that coordinate so Excel will not shift it during auto-fill
- Absolute references like $D$1 keep key lookup or constant values pinned while surrounding relative references shift row by row
- Without the dollar sign, dragging down causes the reference to drift into empty cells below the target rate
- Excel follows standard math order of operations, performing multiplication and division before addition and subtraction
- Wrapping an operation in parentheses forces Excel to evaluate that part first
- Without parentheses, mixed formulas like addition followed by multiplication will prioritize the multiplication step
- Sorting only a highlighted column reorganizes that column while leaving adjacent columns untouched, scrambling record rows
