This is CRAZY!!!. I stumbled on a weird use for FILTERXML() while reading a forum post earlier today. So I couldn’t wait to test it. I am happy to share the results.
Say you have some text (sentence / phrase / keyword etc.) in a cell and you want to extract the nth word. Unfortunately Excel doesn’t have SPLIT() formula. So we end up writing obscenely long array formulas or use gazillion helper columns.
Here is the super sneaky trick. Use FILTERXML() instead.Continue »
Here is an interesting problem to start your day.
Let’s say you work as DNA sequencing engineer at The Enterprise. And you just unlocked the sequence that is responsible for all male problems. The early onset of baldness. The sequence code is AAAA. And you want to find out how many times this sequence is found in a sample of DNA strings, in the range B6:B19. Essentially you want the above.
So how do you write the formula?Continue »
In case, this is the first time you are hearing about Excel formula wildcards, check out the Using wildcards in Excel VLOOKUP formula tutorial.
So you know about wild cards like * ?, now how would you tell VLOOKUP to ignore them?
Say, you are genuinely interested in looking the value “* Payroll” in a lookup table. What then?
This is exactly the problem faced by Peter in our forum post VLOOKUP and cells with “*” NOT to be interpreted as wildcardContinue »
If you deal with customers or colleagues in Europe, often you may see numbers like this:
When these numbers are pasted in Excel, they become text, because Excel can’t understand them.

Use NUMBERVALUE() Function.Continue »
Recently my iPhone 4 crashed. It is 3.5 years old. And just like any other 3 year old, it started acting weird & crazy one night. The next morning it went silent. It won’t go beyond the Apple logo whenever I start it. Since I couldn’t wait for the phone to start, I took out the SIM card (the phone is unlocked, if you are wondering) and placed it in my old Nokia phone. But alas, none of my contacts are on the SIM. They are in “cloud”.
After a day of answering phone calls from everyone including my mom as “Chandoo here”, I’ve decided to get my contacts back. So I logged in to iCloud to download a backup. And the backup was a .VCF file.
Since I wanted to have all my contact numbers in a spreadsheet, I did what any Excel nerd would do. I built a template that can convert VCF data to Excel worksheet.Continue »
Sometimes you think you know something and then suddenly you are surprised. Yesterday was such a moment for me. I have been using Excel for almost a decade now. So naturally I assumed that I know it well. But then yesterday, while doing something I stumbled on a strange screen in Excel that looked like very popular Angry birds game. So I got searching. But there was no mention of it anywhere on net. Then I asked my friend Rollf ‘O’ Pai, who is in Micros0ft Execl team. First he denied such a thing. But we knew each other so well that he could never lie to me. So he confided. He told me what I had suspected for several years.
There is an Angry birds like video game buried in Excel!!! It was meant to be an Easter egg in Excel 2010 (and 2013), but due to backlash from senior management no one ever published the details about it.
So I asked him “How do I unlock it?”. Rollf ‘O’ Pai asked me to never reveal it to anyone and then told me the recipe.
Once I unlocked I could not believe how cool it is!
Read on to understand how to unlock this game.Continue »

It is no exaggeration that knowing excel formulas can give you a career boost. From someone starting at the long list of numbers, you can suddenly become a data god who can lookup, manipulate and analyze any spreadsheet.

Often when you are writing code or testing an application, it might be helpful to have random phone numbers generated for you. Here is an excel formula that I use: =value(left(substitute(rand(),”0.”,””),10)) try these 2 instead (thanks to John) =RAND()*(9999999999-1000000000)+1000000000 =RANDBETWEEN(1000000000,9999999999) [needs analysis toolpack add-in or excel 2007] Even though it works most of the time […]Continue »
