What is a Microsoft Excel Add-in

What is an Add-in? An add-in is software that adds new features into Microsoft Excel. Add-ins save you time. Using an add-in helps to avoid errors and do repetitious work in minutes that could take hours manually. For example, the Spreadsheet Assistant adds over 200 time-saving features to Microsoft Excel.

We have created many Microsoft Excel add-ins to do many tasks related to data, accounting, business analysis, charting, and specialty needs. All are menu-driven for ease of use, and all have help and exercise files to make learning to use easy. And, we have two downloadable books on how to write your own Excel macros.
