An Excel "file" is a workbook... like a three-ring binder full of pages. Each "page" is a worksheet. When you open or save a workbook, you are opening/saving every sheet in it. We are no longer dealing with individual "spreadsheets," each saved with a different name. Imagine the workbook (or "file") name as the name of the three-ring binder.
Excel's workbooks are its documents.
Each worksheet can contain 256 columns and over 16,000 rows. The name of the sheet appears on the sheet's tab, just like a tab on a page of a three-ring binder. Click a worksheet's tab to select it and "pull it to the top." If necessary, use the tab scroll buttons to locate the tab you desire.
These procedures will help you effectively manage workbooks and worksheets.
