SituationVLOOKUP is great for extracting information from a huge data table based on what you are looking for. But what if you need to extract more than one column of information? For eg. Lets say you have salesperson’s name in left most column, and monthly sales figures in next columns, one for each month. Now, you want to find the total sales made by a given sales person. How do you go about it? Read more to find how to solve this.

VLOOKUP (and other lookup formulas) are very powerful and quite practical. They can fetch you the information you are looking for from a heap of data.

Now that we have seen the power of VLOOKUP thru several posts this week, I want to test your understanding of these formulas by presenting 3 challenges. The challenges are, (1) Calculating amount payable after applying quantity discounts, (2) Calculating amount payable after applying accumulated quantity discounts, (3) Calculating unit price after finding the closest match.

Once you start using Excel to develop systems, budget, forecast and large tables of data you may come across the dilemma of “How do I know this is right” or “How do I truth check this”.
This post will add a tool to your arsenal to help you out.

Quick Summary: Recently I have had the opportunity to test Daniel Ferry’s Excel Hero Academy online training program. In this post I am going tell why it is a good program to learn Excel.

Ok, you have learned how to write vlookup formulas. You have also seen some pretty interesting examples of it (1, 2).

But how do you write better VLOOKUP formulas?

Here is a list of 6 tips that work wonders with VLOOKUP writing.

SituationNot always we want to lookup values based on one search parameter. For eg. Imagine you have data like below and you want to find how much sales Joseph made in January 2007 in North region for product “Fast car”? Read more to find how to solve this.

Situation

There is no argument that VLOOKUP is a beautiful & useful formula. But it suffers from one nagging limitation. It cannot go left.

Let me explain, Imagine you have data like below. Now, if you want to find-out who is the sales person who made $2,133 in sales, there is no way VLOOKUP can come to rescue. This is because, once you search a list using VLOOKUP, you can only return corresponding items from the column at right, not at left.

One easy fix would be move the sales data to the left of person name. But this is an annoying fix, because, god knows you may want to lookup based on profit values or something else in future. A better alternative is,…

Situation

Sometimes we don’t know what we want. If this happens when I am in a bar, I usually order a cocktail. Just a mix of everything. The same will work in Excel too.

For eg. If you have lots of data, but the value you want to look up needs to change based on whims and fancies of your users, then you can resort to a cocktail. A mix of VLOOKUP with Drop down lists (Data validation)

Situation

Often we need our lookup formulas to go wild. Not in the sense of go-wild-and-chomp-a-few-kilo-bytes-of-data sense. But wild like wild cards. For eg. In the below data, we may not remember the full name of sales person, but we know that her name starts with jac. Now how do you get the sales amount for that person?

I often tell my excel school students that learning VLOOKUP formulas will change your basic approach towards data. You will suddenly feel that you have discovered a superman cape in your attic. It is that awesome.
What does VLOOKUP really do?

Imagine you have a list of data and you want answer a question like, “How many sales did Josh make?”

VLOOKUP is one of the formulas you can use in this situation. VLOOKUP searches a list for a value in left most column and returns corresponding value from adjacent columns.

Hi all,

Few weeks back, I had a mild internet outage. Since I didn’t know what to do, I turned to you for help and asked you to share “VLOOKUP tips” while I get my connection back.

Oh boy!, the response to that has been overwhelming. More than 50 comments were posted, each with unique, fabulous uses of VLOOKUP & Other lookup formulas.

VLOOKUP is such an important formula that, I cannot imagine preparing a dashboard, report or any other data intensive workbook without using it a few times. So, to celebrate the versatility and usefulness of this beautiful formula (and other lookup formulas) we are going to call this as VLOOKUP week @ chandoo.org.
