In the spirit of Halloween, I’d like to have a little bit of fun with our spreadsheets. In today’s post, we’ll go over a few ways to make your spreadsheet a little more spooky. Obviously, my choices of images / sounds are pretty innocuous, and that’s on purpose. I’m just looking to give you some ideas and hope you have as much fun with this as I had making this post. Also, please don’t give anyone a heart attack 🙂
I DO NOT RECOMMEND USING THESE FOR ANY CRITICAL SPREADSHEET YOU USE. If you decide to do this, please use a dummy workbook with fake data. Never ever ever use a real spreadsheet for this kind of thing. It’s just too dangerous and I really don’t want to see you get in trouble over something silly like this.
That said, please spook responsibly.
Put in a Scary Background Image
You can find free images from Pixabay. I found this spooky ghost image that I’ll use to update my spreadsheet background (ok, I know it’s not spooky, but, hey, I’m trying to get that SEO 😀 ).
In your spreadsheet, go to View->Background.

Then just select your image. You should see your image in the background:
To delete the background image, simply go to View -> Delete Background.
Make Data Flicker
Another way to make a spreadsheet a little more eerie is by having some random data flicker.
For this example, I simply started off by using a pre-made template by click on File -> New From Template.
Next, I opened up the VB Editor and added the following code to the ThisWorkbook module:
If you’d like me to describe what’s happening here in detail, please let me know in the comments below.
Basically, what happens here is that we wait for the user to make a change to the workbook within one of the worksheets. Then it gets all cells that are within the visible window and filters down to just the numbers on the screen (that are not formulas). Of those visible cells with numbers in them, it will choose a random one and make it flicker by changing its value back and forth.
Again, please don’t use this for any real spreadsheet you use for your work since this VBA code messes with your data.
Add a Spooky Noise
Another way to make your spreadsheet a little more creepy is by having a sound play at random times.
For fun, let’s have an evil laugh play after the worksheet calculates and there is an error on the screen. We’ll also color the cells with errors red for an added effect. For a free MP3 download, check out SoundBible.com.
The code to play the sound will be different between Windows and Mac.
Play a Spooky Noise on a Mac
Boy, this was a lot to figure out. It’s a little bit complicated, but with the help of StackOverflow and some tweaking things a bit, I was able to come up with this code snippet (add this to whichever Worksheet module you want to use this in):
It looks at the worksheet that is being calculated (the worksheet that you put this VBA code in). It then waits to find an error that is visible on the screen and when it does, it will turn all errors red and play the evil laugh.
Be sure to create an AppleScript file like the following:
Place this file within the directory listed in the StackOverflow answer (for me, it was
You need to have a formula that results in an error on the worksheet that you put this code in. What I ended up doing was creating a formula that will randomly generate an error:
And then copied down.
The kind of crummy part about this solution is that you have to be able to get that file on someone’s computer in order to get this to work right. However, you could have someone come to your computer and let them run into the issue.
Play a Spooky Noise on Windows
This one was a little easier to find on the web. This is the same concept as the Mac version (find cells with errors after a sheet calculate event, then mark the error cells red and play a sound).
However, the only caveat here is that you must use a wav file (mp3 didn’t work for me).
This one is much easier to distribute if you can put the spooky sound on a common directory that your co-workers have access to.
