The references worth keeping open in a second tab: shortcuts that actually save time, formulas worth memorising, and templates with working logic rather than screenshots.
Shortcuts that repay learning them
Not a list of every shortcut — the eight that change how quickly you work.
| Shortcut | What it does |
|---|---|
| Ctrl + Shift + L | Toggle filters on the current range |
| Ctrl + T | Convert a range into a real table — formulas then expand automatically |
| Alt + = | Insert a SUM over the range above |
| F4 | Cycle absolute and relative anchors on the reference under the cursor |
| Ctrl + Shift + V | Paste special — the fastest way to paste values only |
| Ctrl + End | Jump to the last used cell — reveals a bloated used range instantly |
| Alt + F1 | Insert a chart from the selected range |
| Ctrl + grave | Show formulas instead of results across the whole sheet |
Formula cheat sheet
Copy it, adjust the ranges, done.
=XLOOKUP(A2, $B$2:$B$500, $D$2:$D$500, "Not found")Exact-match lookup that survives a column being inserted
=SUMIFS($D:$D, $B:$B, "West", $A:$A, ">="&DATE(2025,1,1))Sum with several conditions, including a date bound
=TEXTJOIN(", ", TRUE, A2:A10)Join values with a separator, skipping blanks
=IFERROR(VALUE(SUBSTITUTE(A2,"$","")), 0)Turn currency text into a real number without breaking on bad rows
=LET(rate, B1, base, C2, base * (1 + rate))Name intermediate values so a long formula stays readable and computes each part once
=SORT(UNIQUE(FILTER(B2:B500, C2:C500="Active")))A distinct, sorted list of the values that match a condition
