Protection

Dear Laura

Thank you for attending Excel 2007 Intermediate course. I hope you enjoyed the training.

There are 65,536 rows and 256 columns in one worksheet in Excel 2000, 2002, and 2003. It means that they are 16,777,216 cells in one sheet and by default they all are locked. So once you protect your worksheet the user is not allowed to enter any data in those cells.

In Excel 2007 the rows numbers have increased to 1,048, 576 rows and 16384 Columns.

The main reason for unlocking cells is so that once you have protected the entire sheet you can allow the user to edit information in the unlocked cells.

To unlock cells please follow these steps:

Step 1: Select all the cells that you wish to allow the user to edit after protecting the sheet.
Step 2: Right-click within the selected range and select [b]Format Cells
