Preface
Millions of Microsoft Excel users are busy creating and sharing spread-
sheetseveryday.Indeed,thespreadsheethasgrownfromapowerfulconve-
niencetoatransformativefoundationformanybusinesses,drivingdecision-
making around the planet.
AlthoughExcelisacriticaltool,manyExcelusersknowonlyaboutasubset
of its functionality. They utilize the pieces they need, often reusing more
complex pieces from existing templates, and don’t dive too deeply into
everything Excel has to offer. Odds are good that no single user actually
needs every feature in Excel, so this approach is pretty reasonable. At the
same time, though, it means a lot of people never get far enough along the
learning curve to see the techniques they can use to make their work much
easier.
WiththereleaseofMSOffice2007comesanewversionofExcel.Thereare
many changes with Excel 2007, the most obvious being the new user inter-
face.Theintroductionoftheribbonprovidesaresults-orientedinterfacethat
presents tools when you need them, in a clear and organized fashion. The
sizeofaspreadsheethasalsobeengreatlyincreased,withthenumberofcol-
umns now well over 16,000 and the number of rows over 1,000,000. The
total amount of memory that Excel can use has also been increased and is
limited only by the maximum available memory Windows will allow on
your PC.
Other improvements include easier use of PivotTables, conditional format-
ting and named ranges, live visual previews, predefined style galleries, table
formats, and SmartArt graphics allowing you to use more complicated
graphics in your spreadsheets. As most of us are usually required to work
acrossarangeofapplications,shareworkbooks,andconnectwiththeWeb,
Excel 2007 makes this much more user-friendly and easy to manage.
