Modify Cell Content - Replace Small Values With Text

From Q
Jump to navigation Jump to search

This rule allows you to choose a statistic, a value and replacement text, and any cell with a value below that level will be replaced with the specified text.


Here we have chosen to replace any cell that has a Column % value smaller than 2% with "<2%".
