Using LAMBDA - the Ultimate Excel Function (ROI/NI)

Format

This course will be delivered via Zoom. The Zoom link will be emailed to participants the day before the course is due to take place.

Who should attend

Participants on this course should be comfortable with Excel and creating sheets with complex formulas. Attendance on our Excel Intermediate and Excel Advanced courses or having equivalent knowledge is recommended.

Course overview

LAMBDA allows you to greatly simplify complex formulas by breaking them into small and simple user defined functions (Lambdas) without needing VBA coding. Simplifying complex formulas will make your spreadsheets more understandable, maintainable, secure and with less potential for errors.

LAMBDA and the associated Lambda Helper Functions along with Dynamic Arrays and the LET function will radically improve the way complex spreadsheets are written. Understanding these innovations is vital for any Excel Power User.

  All participants should please note the following

  • Test session. If you would like to test your connection and setup prior to your course, please contact info@professional.ie or 016627700 and we will arrange this with you.
  • Two monitors. Having two monitors is very strongly recommended for this training. It allows you to view the trainers PC in one monitor and the application that is the subject of the training in the other. On a single screen it can be difficult to arrange the trainers screen and your own application comfortably. If you only have a single screen please inform the trainer - ideally before the test session - and they can help you to get the best from the training session.
  • Microsoft Office version. We use Microsoft Office 365 Professional. If you are using an older version please be aware that you might not be able to do some of the exercises that are using the latest features.
  • Windows 10. We prepare the files and deliver the course using Windows 10. If you are using a MacBook or other platform please be aware that there can sometimes be incompatibilities and there are certain features that are not available on the Macintosh edition of Microsoft Office 365 Professional. These issues can be identified and resolved during the test session.
