Hi @Hugh Secomb
As Viorel suggested, the referenced cells that original rule defined will not change after using Excel's Format Painter copy the rules and paste to other cells.
But this will not affect the actual effect of the rule. Cells which this rule applies to will match the corresponding reference cells to follow the rule.
For example, the following rules are applied to F48.
If I use Format Painter copy the rules and paste to Cell F45 to F58, the rules also work.
The rules applied to F48:F58 are shown in following image. The cells referenced in the rules have not changed, only the range to which the rules apply has changed.
