In a recent consulting assignment I had a tricky data validation problem. The customer wanted to have an either-or condition in the data validation, like this:
My initial reaction to this requirement was “hmm… that is not possible“. But before shooting the email back to client, I got curious and checked if excel data validation can actually do this. And of course we can do this in Excel with ease.
First see the demo of how this would work:
Now to the specifics:
- Select both cells where you want this data validation to be applied.
- Now go to data validation (Data Ribbon > Data Validation or Data Menu > Validation)
- Specify validation type as “Custom” and use a formula like COUNTA() to check count of cells with a value (see the illustration)
- Optional: Use Error Message settings to set a message you prefer.
- That is all. Now your Either Or Data Validation set up is done.

Hi,
I downloaded this 2025 Calendar template. I checked the custom tab. Is it possible to change the weekend Fri & Sat.
Thanks
It is. Just use the option for fri & sat weekend (should be 7).
Activities of some dates are not getting displayed on "Any month" and "printable calendar" sheets.
e.g. Activity of 24 Apr 25.
Can you check again? The date in "planner" sheet should be a proper date. When I tested with 24-apr-2025, it works.
Love this calendar... I have highlight planner dates enabled but all dates are blue, is it possible to customize the color based on the type assigned to each date?
What would be the right way to add more Holidays in the Customizations?
Inserting rows in the Holiday List causes the blank cells in the calendar to turn Blue.
This is amazing!!! The best I've seen so far!! Is it possible to update it to consider a column for the final date? That way, if an event lasts more than one day, it repeats in the calendar
How do we change/insert the customization "Icon Options" ?
You can adjust these from the settings tab.
Is there anyway this can turn into an academic calendar (ie. start month is July and runs all the way through June of next year)?
Is there a way to make it something that is more than a day without having to add it to every day of that week.
