# How to calculate GST at 15% using Excel formulas

I have been asked twice in one week how to write Excel formulas to calculate GST at the rate of 15%.

You can find information on how to calculate the rate on the NZ Inland Revenue website. I’ve taken this a step further and put together a tutorial on how to put these calculations into Excel formulas. Read more

# Excel – Using VLOOKUP to compare two lists

Years ago the Training and Development manager of a large organisation invited me to spend some time in their Accounts department in order to observe how the Accounts team dealt with their day-to-day tasks. My job was to report on any process that could be improved using Microsoft® Excel.

I’ll always remember asking one of the team (a “just-out-of-school” new recruit) what he was working on after I’d observed him sitting with a red biro and a ruler, diligently drawing red lines on 2 separate sheets of paper. It turned out he was trying to reconcile a customer’s account. Read more

# Excel – How can I do a VLOOKUP based on more than one value?

There are times when you want to return a match for a VLOOKUP based on two values, not one.  For example, we may have customers who have multiple branches.  Each branch is recorded under the same customer number.  So how do we look up info for a specific branch if all of the branches are using the same customer number?

# Excel – Paste a link and Paste Special transpose your data

Without a doubt ‘Paste Link’ is one of the best time-saving features in Excel.  Linking information from one cell to another saves you from having to update data in several places.

Another fabulous time-saving feature is ‘Paste Special Transpose’. This allows you to copy a horizontal range and paste it vertically, or vice versa. An absolute gem.

But have you ever tried to use the two together?  It isn’t easy at all.  In this post I want to share a wee work-around that will allow you to use the Paste Link and Paste Special Transpose features together. Read more

# Excel – How do I sum a range of cells that include #N/A or #DIV/0! errors?

I think most of us will agree that error values can be helpful, and sometimes extremely unhelpful.  For example, the #N/A error (Value Not Available error) is very helpful when cross-referencing two lists using the VLOOKUP function.  If Excel can’t find a lookup value the #N/A error makes it very obvious.

However if you are wanting to total a range that includes #N/A errors all of a sudden they aren’t so special any more.  Read more

# Excel – Retaining a leading 0 (zero) when entering Post Codes – great for mail merging

PROBLEM: When you enter a post code that has a leading 0 (zero), e.g. 0642, you see only the last 4 digits, not the leading zero.  This is especially frustrating when using an Excel file in a Mail Merge!

SOLUTION: learn how make the 0 stay!

SOLUTION: learn the relative to absolute shortcut key!
