Use the ISODD and COLUMN functions to determine odd columns
In this example, we want to determine whether a column’s index in a range is even or odd, and then fill each odd row with the character “X”. Use the ISODD function in combination with IF and COLUMN() to get the result shown in the image below. If this function is not available and returns an error, install and load the Analysis
ToolPak add-in.
To determine odd columns:
- Select cells A1:E11 and type the following formula: =IF(ISODD(COLUMN()),”X”,”").
- Press Ctrl+Enter.
To mark even columns, type the following formula: =IF(ISEVEN(COLUMN()),”X”,”").
This tip is compatible with Excel 97, 2000, 2003 and 2007.
