What can I do for you?

Whichever type of Excel or Access application or training you need, you've come to the right place to find expert help.

I am an Excel and VBA expert (some people would say guru) with in-depth knowledge of Excel and VBA. Of course there are some areas I am particularly experienced in. These include:

  • Developing bespoke Excel models and add-ins completely tailored to your needs.
  • Professionalizing your Excel model (add navigation, make formatting consistent, apply styles, add data validation, streamline the work-process within the model).
  • Developing add-ins for Excel on-line (and Excel in Teams) using Office JavaScript
  • Create Office scripts for you which work with Excel on-line (in a browser or in Teams)
  • Building sophisticated and user-friendly Excel templates for modeling and data entry.
  • Writing professional VBA code to automate tasks within your projects.
  • Salvaging problematic workbooks: Getting rid of corruptions, removing excess formatting, recovering from crashes.
  • Enabling your Spreadsheet model to fetch data from and/or update data to external systems.
  • Create a custom Excel and/or VBA training just for you.

To get an impression of my level of expertise, a few examples of Excel add-ins and utilities developed by me can be found on my download pages.

Take a moment to browse through the Excel articles I have posted on this site, you may find something useful there too.
