Excel and Outliers

New functions make it easier to find them

Malcolm Gladwell’s book Outliers is a great read – I reviewed it here. Its premise is that some outliers (events that are far outside “normal” expectations) have causes and hence are worthy of investigation. Excel have some functions that can help identify outliers in your data.

Excel Formula to Extract the Domain

Using the SUBSTITUTE function

I recently read a blog post about using Excel for SEO (Search Engine Optimisation). It mentioned a function to extract a domain from a URL. The function was from Google docs, not Excel. So I wrote an Excel formula to extract the domain from their list of URLs.

Handling DR and CR at the end of numbers in Excel

Sorting out debits and credits

Some systems add DR and CR to the end of numbers when they export into Excel. This renders the values useless for normal calculations. You can use data cleansing techniques to remove the characters using formulas or Power Query. There is one function however that can perform calculations on these types of entries.

Making Subtotals Bold

When you use the SUBTOTAL feature in the Data ribbon tab it automatically inserts subtotals in your list – see blog post on it here.

One problem with this is that is only makes the cell with the word Total bold – it doesn’t make the whole row bold.

If you want the whole row to be bold it isn’t hard to fix.

  1. Select the whole range involved.
  2. Use the grouping button 2 top left corner. See image below.
  3. Then hold the Alt key down and press the ; (semicolon key) – this selects just the visible cells.
  4. Then press Ctrl + b to bold it.
  5. Click another cell to reset the range and you are done.
