Use Text Format to Preserve Leading Zeros in Excel [Quick Tip]
Here is a quick tip to add awesome to your Wednesday.
If you want to enter numbers like 00023 or 023.340 or 23.34500 in your Excel sheet, you would notice that Excel magically removes leading zeros and trailing zeros (after decimal point) as the number 23 is same as 00023. But sometime, we want 00023, not 23. Then what?!?
Very simple, we use TEXT format instead of number format. Just select the cells where you are going to enter these numbers, and from Home ribbon > Number area, select “Text” as cell type. This tells Excel to treat any value you enter as Text, not as number. So when you type 00023, it will appear as 00023.Continue »

Learn Statistics & Probability using MS Excel
One of the most dreaded courses during my under-graduation is Probability, Statistics & Queuing Theory. We called it PSQT. I struggled to understand the significance and concept of this course as I could barely concentrate in the class. We had a professor, who is probably a genius, but the moment he started the class, I would magically fall in to one of my after-noon naps. When I woke up, we are either in the middle of an elaborate t-test or going thru intricacies of a Markovian queue.
This was all 11 years ago. Later in life, I have embraced the world of probability & statistics. I still fear queues. May be I will get there one day. 😉
A good understanding of statistics & probability theory is necessary if you want to model complex real-life problems using Excel or similar tools. Naturally, Excel has several functions, features & supported add-ins to help you in this area.
Today, I want to share some of this with you. This article is broken down in to 3 parts.
- Learning Statistics & Probability using Excel
- Downloadable Excel Workbooks to understand
- Full blown models & simulations in Excel

Comparing 2 Lists with a Twist
We love to compare. The instinct to compare leaves no one. Even my two year old twins compare their toys with each other (and fight).
It would make Excel hugely popular if Microsoft builds a handy data comparison tool right in to it. Alas, they have customizable ribbon, 3d effects & equation editor…
Since comparison is one of the main uses of Excel, we have written extensively about it here.
But there is always one more interesting comparison problem. Today, I want to share one such problem, based on a comment left by N-Man.Continue »
