I need to preserve some historical data that has conditional formatting applied to it. Going forward with this spreadsheet, I will be changing the “trigger” for the conditional formatting but I don’t want to lose the formatting of the historical data that had the old trigger. My conditional formatting, if the conditions are met, will turn the cell data either green or red but the cell value that determines this is changing as of next week. How can I keep all the old data intact?
Thank you.
