How to make every other row shaded in excel

Answer

To make every other row shaded in Excel, select your data range, navigate to the Home tab, click Conditional Formatting, choose New Rule, select "Use a formula to determine which cells to format," enter the formula =MOD(ROW(),2)=0, click Format to choose your shading color, and click OK twice.

Understanding Row Shading

Row shading alternates background colors between rows to improve data readability. The technique works by applying conditional formatting rules that evaluate each row number and assign colors based on whether the row is even or odd.

Using Conditional Formatting with Formulas

Conditional formatting evaluates each cell against specified criteria and applies formatting when conditions are met.

Windows Steps:

1. Select the range where you want alternating row shading
2. Click the Home tab in the ribbon
3. Click Conditional Formatting in the Styles group
4. Select New Rule from the dropdown menu
5. Choose "Use a formula to determine which cells to format"
6. Enter =MOD(ROW(),2)=0 in the formula box for even rows or =MOD(ROW(),2)=1 for odd rows
7. Click the Format button
8. Select the Fill tab in the Format Cells dialog
9. Choose your desired shade color
10. Click OK to close the Format Cells dialog
11. Click OK to apply the rule

Mac Steps:

The process remains identical on Mac, with the same menu locations and formula syntax.

Formula Explanation

The MOD function returns the remainder after division. ROW() returns the current row number. MOD(ROW(),2) divides the row number by 2 and returns 0 for even rows and 1 for odd rows. The comparison operator checks whether the result equals your target value.

Using Excel Tables for Automatic Banding

Excel Tables provide built-in alternating row colors without formulas.

1. Select your data range
2. Press Ctrl+T on Windows or Cmd+T on Mac to create a table
3. Check "My table has headers" if your first row contains headers
4. Click OK
5. The table applies alternating row shading automatically
6. Modify banding colors through the Table Design tab by selecting different table styles

The Table Design tab appears when you click inside the table. Windows users find it in the ribbon after table creation. Mac users access it the same way.

Removing Table Formatting While Keeping Shading

Converting a table back to a normal range preserves the alternating colors.

1. Click anywhere inside the table
2. Navigate to the Table Design tab
3. Click Convert to Range in the Tools group
4. Click Yes in the confirmation dialog
5. The alternating colors remain applied to the cells

Adjusting Shading for Specific Row Patterns

Different formulas create various shading patterns beyond simple alternation.

For shading every third row: =MOD(ROW(),3)=0

For shading two rows, skipping one: =MOD(ROW()-1,3)<2

For starting shading at a specific row (row 5): =MOD(ROW()-5,2)=0

Applying Shading to Entire Rows Versus Specific Columns

The cell selection before creating the conditional formatting rule determines the shading scope. Selecting columns A through E applies shading only to those columns. Selecting entire rows by clicking row numbers applies shading across all columns.

Modifying Existing Conditional Formatting Rules

Changes to shading colors or patterns require editing the conditional formatting rule.

1. Select the formatted range
2. Click Conditional Formatting on the Home tab
3. Select Manage Rules
4. Choose "This Worksheet" or "Current Selection" from the dropdown
5. Select the rule you want to modify
6. Click Edit Rule
7. Adjust the formula or click Format to change colors
8. Click OK twice to apply changes

Copying Shaded Formatting to Other Ranges

Format Painter transfers conditional formatting between ranges.

1. Select a cell with the alternating row formatting
2. Click Format Painter in the Clipboard group on the Home tab
3. Click and drag across the destination range
4. The conditional formatting applies to the new selection with adjusted row references

Troubleshooting Common Issues

Shading Doesn't Alternate Properly: The formula references absolute row numbers instead of relative references. Remove dollar signs from the ROW() function. The correct formula uses ROW() without $ symbols.

Shading Disappears When Filtering: Conditional formatting evaluates hidden rows. The MOD function counts all rows including filtered ones. Use SUBTOTAL functions within conditional formatting for filter-aware shading, though this requires more complex formulas.

Colors Don't Match Expectations: The rule order in Manage Rules affects which formatting displays. Rules at the top of the list take precedence over lower rules. Reorder rules by selecting them and clicking the up or down arrows.

Performance Considerations with Large Datasets

Conditional formatting recalculates when worksheet changes occur. Datasets exceeding 10,000 rows may experience slower performance with complex conditional formatting rules. Excel Tables with built-in banding perform better than formula-based conditional formatting on large datasets because the formatting is applied directly rather than evaluated continuously.

Combining Multiple Formatting Rules

Multiple conditional formatting rules can coexist on the same range. Adding rules for highlighting specific values works alongside alternating row shading. The "Stop If True" checkbox in Manage Rules prevents lower-priority rules from applying when higher-priority rules match.

Alternative Methods Using Manual Formatting

Manual fill colors provide a non-dynamic option without formulas.

1. Select the first row you want to shade
2. Hold Ctrl on Windows or Cmd on Mac
3. Click additional rows while holding the key to select multiple non-contiguous rows
4. Click the Fill Color button on the Home tab
5. Choose your desired color

This method requires manual updates when rows are inserted or deleted, unlike conditional formatting, which adjusts automatically.
