When working with a large number of worksheets in an Excel workbook, it can be difficult to keep track of which worksheet is which. This is especially true if the worksheets are not labeled or if they are labeled with generic names (e.g., Sheet1, Sheet2, etc.).
One way to determine a worksheet's number is to look at the tabs at the bottom of the Excel window. Each tab corresponds to a different worksheet in the workbook, and the tabs are numbered from left to right. So, if you see a tab labeled "Sheet3", you can be sure that it is the third worksheet in the workbook.
Another way to determine a worksheet's number is to use the "Select All" button. This button is located in the upper-left corner of the worksheet, to the left of column A and above row 1. When you click on this button, all of the cells in the worksheet will be selected. The name of the worksheet will then appear in the formula bar above the worksheet, and this name will include the sheet's number (e.g., Sheet1!A1).
You can also use the "Name Box" to determine a worksheet's number. The Name Box is located next to the "Select All" button and displays the address of the currently selected cell. However, unlike the formula bar, it also displays the sheet's number along with its name (e.g., Sheet1:A1).
Finally, you can use VBA to determine a worksheet's number. The following code will return the number of the active sheet:
