Microsoft Excel contains a very powerful programming language called
Visual Basic for Applications (VBA). This language can be used to
extend its capabilities, facilitate its use, and/or interface with
other Microsoft Office products like Outlook, Word, Access, or
Powerpoint. An add-in is an invisible Excel Workbook that
contains macros in Visual Basic code which makes all this happen. With
Spinnaker Spreadsheet Add-ins the code is activated through the use of custom
toolbars, which we feel simplifies its installation and use.
We divide our add-ins into the four categories below and invite you
to explore them.
We really enjoy creating custom products for our clients, and we
welcome new ideas and challenges. Our Custom Add-ins page will
introduce you to some of the custom work that we have already done,
let you read about what some of our customers have said about us, and
hopefully spark some of your own ideas. The wonderful thing
about a custom application is that you get exactly what you need. You won't get saddled with an expensive program that sits
90% idle while you use only 10%.
We have tried to develop generic shareware add-ins to appeal to
casual users of Excel as well as power users and developers. In
general we offer these products as examples of what can be done with
Excel. They are intended to help make Excel an even more
powerful tool than it already is. Many of these add-ins
originated as custom products that we thought would be of general
interest. We sincerely hope you find them useful. If you
find yourself unsure about whether one of our add-ins will do what you need,
feel free to contact us at firstname.lastname@example.org
(replies within 24 hours, usually a lot sooner). If you want a more
personal touch, you can also call us at 603-206-9977 during US Eastern time

Some customers have expressed interest in our add-in
registration process. We have developed Spinnaker Registrations
for add-in and spreadsheet developers who have a need to protect
their own products. The setup
program we use for all our add-ins is called Inno Setup, which is a freeware
that you can download from http://www.jrsoftware.org.
We liked it so much that we decided not to develop our own setup program.
