Excel Conditional Formatting AND

What this does

Conditional formatting applies a fill, font or border automatically while a condition is true and removes it when it stops being true. The built-in presets cover simple cases; a formula rule handles everything else, including formatting a cell based on another cell. Excel evaluates the formula once per cell in the Applies to range, shifting relative references as it moves — so the $ anchors decide what each cell actually tests. Keep the inputs visible and clearly labelled and the whole thing stays auditable — anyone who opens the file later, including you, can see at a glance exactly what feeds the result and change one assumption without hunting through the formula. Treat “excel conditional formatting and” as a small repeatable workflow rather than a one-off click you hope to remember next time. Use a small test block before the live file, so any surprise in the affected cells shows up while it is still harmless. When a formula is involved, keep the inputs labelled beside it, reference cells instead of typing values, and apply number formatting only after the result checks out. That turns a workspace setting that makes a big sheet comfortable to navigate into a method you can reuse, explain, and defend when the workbook leaves your screen.

A worked example

Orders sit in A2:D10 with amounts in column B: B2 is 150, B3 is 80, B4 is 230. Select A2:D10, add the formula rule =$B2>100 and pick a green fill. Rows 2 and 4 turn green across all four columns; row 3 stays plain. $B locks the column while the row number stays relative, so every cell in a row tests its own row’s B value — B$2 would instead compare everything against row 2. A formula rule keeps status visible without manual recoloring: overdue rows, high amounts or matching text get marked the moment the data changes. A practical tip before you scale it up: build it once on a small block of test data, confirm the number against the tool on this page, and only then point it at your real sheet. That one habit catches almost every mistake while it is still cheap to fix, long before a wrong figure reaches a report or a colleague.

In Google Sheets

If you are in Google Sheets rather than Excel, the good news is that the formula shown here is identical and the workflow barely changes — menus sit across the top instead of in a ribbon, and a few function names differ slightly, but anything you build here moves across with little or no rework. Keep this page bookmarked for the next time the same question comes up. Better still, rebuild the example once in your own sheet — doing it yourself, with the tool above to check against, is what turns a copied formula into a technique you own. If you take one thing from this page on “excel conditional formatting and”, make it the habit rather than the keystrokes: set the problem up with labelled inputs, reference those cells, and let Excel do the recomputing. Bookmark the page for the syntax, but do the example once in a blank sheet and check it against the tool above — five minutes of hands-on practice fixes the method in memory far better than re-reading, and it surfaces the small snags while they are still harmless. After that the technique is genuinely yours: faster than searching for it again, and reliable enough to drop into work that other people depend on.

Common mistakes

• Writing $B$2 instead of $B2, so every row tests the same single cell.
• Using B$2 for a row-wise rule — that locks the row, not the column.
• Writing the formula for the wrong cell: it must evaluate for the top-left cell of the Applies to range.
• Letting an earlier rule mask a later one instead of reordering in Manage Rules or using Stop If True.
• Comparing text values with > and expecting numeric behavior.
