A Workbook consists of worksheets. A worksheet is a grid of cells organized into 1,048,576 rows and 16,384 columns. Each row is numbered ("1", "2", "3", ..., "1048576"), and each column is lettered ("A", "B", "C", ..., "XFD"). Row and column headings are displayed at the left and at the top of a worksheet, respectively.

Worksheet cells can contain data of different types, and Formulas. These cells can be formatted. Proper cell formatting improves worksheet appearance, and allows end-users to read, find and understand worksheet data easily. When adjusting cell appearance, you can specify font, font size, character style (bold, italic or underline), text alignment, and different colors for the background and foreground. For details on formatting cells, see the Formatting Cells document, as well as the examples in the Formatting Cells section.

All worksheets in a workbook are stored within the WorksheetCollection, which you can access via the IWorkbook.Worksheets property. To get an individual worksheet, use WorksheetCollection.Item. Each worksheet is accessible by its unique name or position within the workbook (see the How to: Access a Worksheet example).

To set the active worksheet within a workbook, use the WorksheetCollection.ActiveWorksheet property (see the How to: Set an Active Worksheet example).
