Someone sent me a workbook in which a simple VLOOKUP formula was returning #N/A errors, instead of the correct results. The product numbers looked the same, but Excel didn't match them in the lookup. Can you solve this VLOOKUP formula error mystery?
Last week, I ran into problems counting Excel data with COUNTIF, and it's Twitter's fault! Why did they do that? The COUNTA function can cause problems too, when it counts cells that look empty. Let's see how to fix both of those issues.
Do you use Excel's SUBSTITUTE function very often? It's a handy way to count items in a cell, when they're separated by commas or spaces. The examples below show different ways to use this function – have you tried the variation in the last example?
As Juliet famously said to Romeo, "What's in a name?" And she was talking about rows (misspelled as "rose"), so maybe Juliet was using a spreadsheet at the time. There are special rules for Excel names, but you might be surprised to see what is allowed.
Long ago, I created a Christmas planner in Excel, and it has evolved over the years. Well, tomorrow is the first of December, so you've probably finished your planning for this year. But, if you haven't, this year's new and improved version of the workbook might help. Now it's an Excel Holiday Planner – you can pick any date as your holiday, instead of being Christmas themed.

Here's an Excel Lookup Formula challenge to get your brain fired up. Can you solve it without doing a Google search? The problem details are shown below, and you can download the sample workbook. It has the sample data, and there are solutions too, on a different worksheet.
With the Excel CONVERT function, you can change quantities from one measurement type to another. For example, a hot day in Celsius looks even worse in Fahrenheit! Get my updated workbook for the CONVERT function, with drop down lists for category, units and prefixes.
If a cell contains a full address, what formulas would you use to show the street address, city, state and zip code in separate cells? That was the challenge that I gave to my weekly newsletter readers. A few rows of the sample data are show below, and you can download the sample file, to see all the data.
If there's just one price per product in an Excel lookup table, you could use the INDEX and MATCH functions to to get that price. But what if the price changes occasionally, and your pricing list has multiple dates and prices for each product? How can you do a product price lookup based on invoice date and product name?
