## Find and Highlight all blank cells in your data [Excel tips]

Published on Apr 20, 2015 in Excel Howtos

True story:

On Friday (17th April – 2015), I flew from Vizag (my town) to Hyderabad so that I can catch a flight to San Francisco to attend a conference. As I had 10 hours of overlay between the flights in Hyderabad, I checked in to a lounge area so that I can watch some sports, eat food while pretending to do work on my laptop. There was a gentleman sitting in adjacent space doing some work in Excel. As I began to compose few emails, the gentleman in next sitting space asked me what I do for living. Our conversation went like this.

Me: I run a software company
He: Oh, so you must be good with computers
Me: smiles and cringes at the stereotyping
He: What is the formula to select all the blank cells in my Excel data and highlight them in Yellow color

Mind you, he had no idea that I work in Excel. We were 2 random guys in airport lounge watching sports and eating miserable food.

Me: Well, what are you trying to do?
He: You see, I am auditing this data. I need to locate all the blank rows and set them in different color so that my staff can fill up missing information. Right now, I am selecting one row at a time and filling the colors. Is there a one step solution to this problem?

Needless to say, I showed him how to do it faster, which led to an interesting 3 hours at the lounge.

End of true story.

So today, let’s understand how to find & highlight all the blank cells in the data.

## Check if a Word or Phrase is Palindrome using Excel Formulas [Weekend Fun]

Published on Aug 12, 2011 in Excel Howtos, Learn Excel

The other day, while I was putting my kids to sleep, this idea came to me. How do I check if a cell contains a palindrome, using Excel formulas?

So, to check if a cell contains palindrome, we need to reverse the cell contents and see if both original and reverse are the same.
