In Excel: use Format as Table and enable Banded Rows, or create a conditional formatting rule with =MOD(ROW(),2)=0.

Choose Format as Table for dynamic data.
Use Banded Rows from Table Design.
For a plain range, add a formula-based conditional formatting rule.
Pick a subtle fill so text remains readable.
What this does
Alternating row color improves scanning by shading every other row. Format as Table is easiest because banding expands with the table. Conditional formatting gives more control and can shade based on visible row numbers, groups or custom logic. Before you run it on a workbook other people depend on, try it on a copy or a few rows first. Undo only reaches back through the current session, so a quick trial run is the cheapest way to see exactly what will change before the file is saved and shared. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “fill every other row in excel”. Start on a copy or a tiny sample, keep the affected rows visible, and compare the result with the tool above before you touch the real workbook. When this is a ribbon command, the selection matters more than the button: confirm the range, apply the command, then spot-check the output before saving. The point is a layout choice that keeps the sheet readable and sortable, but the practical win is that someone else can open the file and understand what happened without asking you.
A worked example
Select A1:F500, choose Home ▸ Format as Table and keep Banded Rows on. For a normal range, select A2:F500, add a conditional formatting formula =MOD(ROW(),2)=0 and choose a light fill. Row banding is small, but it materially improves readability for wide tables and repeated review work. If this is something you do often, add the command to the Quick Access Toolbar (right-click it on the ribbon and choose Add to Quick Access Toolbar) or learn its shortcut, so next time it is one click instead of a hunt through the menus.
In Google Sheets
This is a command rather than a formula, so there is no syntax to carry over. Google Sheets arranges its commands in menus across the top instead of a ribbon, names some of them differently and does not have every Excel command — look for the equivalent in the Sheets menus or its help before assuming the steps match. The aim was to get you unstuck fast and leave you a little more capable than a copy-paste would. The answer is at the top and the detail above shows why it holds — so the next time a colleague asks, you can answer without reaching for search. The short version of “fill every other row in excel”: the answer is at the top of this page, and the sections above explain why each step matters, so a variation of the problem does not stump you. Try it once on a copy of a real file and the steps stick far better than re-reading them.
Common mistakes
- Manually coloring rows, then breaking the pattern after sorting.
- Using colors with poor contrast.
- Applying the rule to only one column.
- Forgetting that inserted rows need the rule range to include them.
Frequently asked questions
What formula shades every other row?
=MOD(ROW(),2)=0 shades even rows.
Will banded rows survive sorting?
Yes when done with a table or conditional formatting.
Can I shade by groups instead?
Yes, but use a helper formula based on group changes.
