I'm curious how correct Chatgpt is to this problem?
For the conditional formatting rule you want to implement, it seems like you need to satisfy two conditions:
- The cell in the second date column should be blank.
- The first date in column A should be at least 4 days ago.
You can combine these two conditions using an AND function in Excel's conditional formatting.
Assuming your first date column is Column A and your second date column is Column B, the formula in conditional formatting would look something like this:
=AND(ISBLANK(�2),A2<TODAY()-4)=AND(ISBLANK(B2),A2<TODAY()-4)
Here's how this formula works:
- ISBLANK($B2) checks if the cell in the second date column (B2 in this example) is blank.
- TODAY()-4 calculates the date 4 days ago.
- $A2<TODAY()-4 checks if the date in the first column (A2 in this example) is at least 4 days ago.
By using AND, you ensure that both conditions must be met for the cell to be formatted.
Steps to apply this conditional formatting:
- Select the range of cells in your second date column where you want to apply the conditional formatting.
- Go to Home -> Conditional Formatting -> New Rule.
- Choose Use a formula to determine which cells to format.
- Enter the formula =AND(ISBLANK($B2), $A2<TODAY()-4) in the formula field.
- Click on Format, choose the red fill color, and click OK.
- Click OK again to apply the conditional formatting rule.
Now, the cells in the second date column should turn red only if they are blank and the corresponding cell in the first date column is at least 4 days old.
