Microsoft Excel can be much more than just a spreadsheet. It has become adevelopment platform in it own right. Applications written using Excel are partof many corporations' core suites of business-critical applications. In spite ofthis, Excel is too often thought of as a hobbyist's platform. While there arenumerous titles on Excel and VBA, until now there have been none thatprovide an overall explanation of how to develop professional-quality Excel-basedapplications. All three authors are professional Excel developers who runtheir own companies developing Excel-based apps for clients ranging fromindividuals to the largest multinational corporations. In this book they showhow anyone from power users to professional developers can increase thespeed and usefulness of their Excel-based apps.

While all the other major languages seem to have a de-facto standard text that explains the commonly-agreed best practices for architecting, designing and developing applications in that language, Excel does not. This book aims to fill that gap.

All three authors are professional Excel developers who run our own companies developing Excel-based applications for clients ranging from individuals to the largest multinational corporations. This book details the approaches we use when designing, developing, distributing and supporting the applications we write for our clients.

This is not a beginner-level book. We assume that the reader will have read and (mostly) understood our Excel 2000/2002 VBA Programmer's Reference, John Walkenbach's Excel N Power Programming or similar titles.

Finally, there's a book that treats Excel as the powerful development platform it really is, and covers every facet of developing commercial-quality Excel applications.

This is not a book for beginners.
