Excel Formula can now be displayed showing numbers and variables. Stop spending endless time tracking down individual cell-references in an Excel formula. Use the XL-Viking Formula Display Functions to show all the numbers and variables that build up a Formula in Excel.
Today we will release XL-Viking v1.01 – this is an update that addresses a recurring issue with the XLVU function,... View Article
Just before we launched we had a request from a client to add some additional functionality to the XL-Viking menu. We have added this video tutorial to cover these useful new functions. Enjoy!
Don’t forget to take a little time and go through the Video Tutorials – The tutorial videos provide guidance for those of... View Article
The wait is finally over! We have been busy for the last few months putting the finishing touches to XL-Viking,... View Article
