VSTO & .NET & Excel

September 3, 2013

Great Articles based on Formulas only!

Filed under: .NET & Excel — Dennis M Wallentin @ 5:54 pm

Whenever I see solutions in MS Excel without the use of VBA it actually reveals the core power with functions and formulas. That’s why I want to highlight the excellent work made up at “E90E50fx….only formulas”.

It says “…only formulas” however it exist at least one article that includes VBA. But they are forgiven 🙂

The following link will take You to the site: https://sites.google.com/site/e90e50fx/home

Now I will go back to other activities excluding MS Excel!


Kind regards,



  1. Hi Dennis. If you like formulas, no doubt you’ll also like the challenges and responses posted at http://chandoo.org/forum/forums/excel-challenges/
    The challenges all call for a single formula, and some of the standouts include:
    * working out if a number above 1048576^2 is a prime number (meaning you can’t simply generate a consecutive array of integers based on the number of rows in a worksheet)
    * producing distinct/duplicate/unique arrays from a list containing text AND numbers
    * Counting the number of times a numeric array occurs in another
    * Doing Two-way interpolation
    * Turn non-contiguous, different sized 1D ranges into one 1D range

    Hours of fun!

    Also, Mike Girvin’s YouTube channel has some great stuff along the same lines.
