About LLC LLC began business in 1994 as Macro Systems, specializing in custom Microsoft Excel macros and add-ins.  In 2007 we became LLC to reflect our focus on Microsoft Excel add-ins.

We are located at 144 Dewberry Drive, Hockessin, Delaware, USA 19707. Our direct phone number is 302-584-1771.   To contact us via e-mail, please use our contact form.   We provide 7 day a week live support from 8AM to 10PM our time:

Our products have been top rated by many of the independent software sites and magazines. Three of our products (Spreadsheet Assistant, Cell Color Assistant, and Sheet Navigator) took the top position for add-ins for Microsoft Excel in a PC Magazine's annual utilities issue.

In Microsoft Press's book on Office 2003, our Spreadsheet Assistant was the only add-in for Microsoft Excel (evaluation copy) distributed on the book's CD.

We view customer satisfaction and the quality of products to be our top priorities.  To that end, we offer a money back guarantee and are continuously improving our products.

We are continually developing new add-ins and expect to release at least six new add-ins each year.
