Workbook Object

workbook.SheetNames is an ordered list of the sheets in the workbook

wb.Sheets[sheetname] returns an object representing the worksheet.

wb.Props is an object storing the standard properties. wb.Custprops stores custom properties. Since the XLS standard properties deviate from the XLSX standard, XLS parsing stores core properties in both places. .

wb.WBProps includes more workbook-level properties:

• Excel supports two epochs (January 1 1900 and January 1 1904), see 1900 vs. 1904 Date System. The workbook's epoch can be determined by examining the workbook's wb.WBProps.date1904 property.
