We all know VLOOKUP (or INDEX+MATCH) as an indispensable tool in our Excel toolbox. But what if you want the lookups to be a little gentler, nicer and relaxed?
Let’s say you want to lookup the amount $330.50 against a list of payments. There is no exact match, but if we look 50 cents in either direction, then we can find a match. Here is a demo of what I mean.
Unfortunately, you can’t convince VLOOKUP to act nice.
Hey VLOOKUP, I know you are awesome and all, but can you cut me some slack here?
VLOOKUP is tough, reliable and has a cold heart. Or is it?
In this post, let’s learn how to do lenient lookups.Continue »

When faced with a tricky time sheet summary problem (as outlined above), after initial lethargy I wanted to solve it.Continue »

Let’s say you have some employee data in employee name, manager name format. But the data is all in one column, with odd rows containing employee names & even rows containing manager names. Something like above.
And you want to find out who is the boss for a given employee. Say, “Andrea Nichols”.
Your regular MATCH() formula for Andrea over the data range returns wrong answer as it will find first occurrence of Andrea (which in this case happens to be on even row, hence a manager record).
So how would you write the lookup formula?Continue »

Over the weekend, I got an email from Mr. E, one of my students. Mr. E works at a police department in California and as part of his work, he was looking at calls received by police. Whenever police get a call for help, multiple teams can respond to the call and go to the location. All of these dispatches are recorded. So a single call can have several such dispatches.
