Numeritas eXcel toolkit – nXt

Now with ‘Cell Tracker’

Several of our clients asked where they could get ‘Cell tracker’, having seen us use it to navigate formulae, so we have rolled it into nXt! Cell tracker breaks down the precedents and dependents of a formula, allowing you to visit each one and highlighting them in context of the full formula. It makes it so much easier to understand a formula, we recommend downloading nXt today!

Additionally, nXt also has several other analytical and productivity tools that we have built for our internal use. And it’s free!

Numeritas has been building and reviewing financial models since 2003. We know what kind of errors crop up in spreadsheets and we know the challenges of building spreadsheets and navigating around them.

Over the years we have built some awesome tools to support our work, which we called the numeritas eXcel toolkit (nXt). Now we are sharing some of the most useful features with you, for free.

In order to obtain this toolkit, first download the nXt installer file below and open it in Excel. Once you have read the agreement and are happy with it, click the install button at the bottom and the software will download and install. You will then have a new ‘NUMERITAS’ tab on your Excel ribbon.

Note that the addin is designed to work with Windows versions of Excel 2007 and newer (both 32 and 64 bit). Unfortunately there is no Mac version available.

The toolkit contains the following:


  • Workbook summary: This report will tell you a wealth of information about each sheet in your workbook including the number of unique formulae, number of formulae returning errors, number of pivot tables, array formulae, charts, shapes, conditional formats, data validations and a number of other items. This report also contains the snappily-named ‘Columnar Unique Formula Profile’ which is essentially a histogram of the number of unique formulae in each column across the sheet. This allows you to easily see which sheets are potentially copies of each other and confirm that the timeline starts in the same place across all sheets.
  • Unique formula listing: This lists every single unique formula in your workbook and provides additional information about each one such as any hard coded text or numbers in the formulae and whether or not they are part of an array. This can be used to better understand what’s in your model and identify certain things you may want to manage.
  • Workbook map: This is a visual representation of the location of unique formulae and their copies within your model. This report can be used to identify improperly copied formulae and unexpected uniques, as well as hard-coded values in the middle of calculation blocks. See this blog post for more information
  • External links in formulae: This will list all external links found in formulae within the model
  • External links in other items: This will check the following items and list any external links it finds:
    • Named ranges
    • OnAction property of shapes
    • Text of DrawingObjects
    • Linked Cell and Fill Range of embedded form controls
    • The following chart elements:
      • Title
      • Series formulae
      • Series datalabels
      • Axes titles
    • Conditional format condition formulae
    • Data validation custom formulae

    • Iterations are enabled
    • Multiple sheets are selected
    • Workbook is in ‘Shared’ mode
    • Workbook is protected
    • Number of external links
    • Number of hidden sheets
    • Number of ‘very’ hidden sheets

    • Sheets with large ranges that have conditional formats applied
    • Large ‘real’ used ranges on sheets
    • Large used ranges on sheets
    • Camera tools
    • Number of hidden names
    • Number of names with external links
    • Number of unique external files referred to by names
    • Number of names with #REF! errors
    • If there are more than 10,000 conditional formats
    • If there are more than 250 names
    • If workbook precision is set as displayed
    • If objects are set to be hidden
    • If objects are set to show placeholders
    • If there are more than 250 styles
