Hide All
Display or hide formulas
Switch between displaying formulas and their values on a worksheet
Press CTRL + ` (grave accent).
Prevent a formula from displaying in the formula bar
Caution This procedure also prevents the cells that contain the formula from being e***ed.
Select the range of cells whose formulas you want to hide. You can also select nonadjacent ranges (nonadjacent selection: A selection of two or more cells or ranges that don''t touch each other. When plotting nonadjacent selections in a chart, make sure that the combined selections form a rectangular shape.) or the entire sheet.
On the Format menu, click Cells, and then click the Protection tab.
Select the Hidden check box.
Click OK.
On the Tools menu, point to Protection, and then click Protect Sheet.
Make sure the Protect worksheet and contents of locked cells check box is selected.
Show formulas that were previously hidden by removing protection
If the workbook is shared (shared workbook: A workbook set up to allow multiple users on a network to view and make changes at the same time. Each user who saves the workbook sees the changes made by other users. You must have Excel 97 or later to modify a shared workbook.), unshare it.
How?
Note Unsharing the workbook deletes the change history (change history: In a shared workbook, information that is maintained about changes made in past e***ing sessions. The information includes the name of the person who made each change, when the change was made, and what data was changed.). If you want to keep a copy of this information, print out the History worksheet (History worksheet: A separate worksheet that lists changes being tracked in a shared workbook, including the name of the person who made the change, when and where it was made, what data was deleted or replaced, and how conflicts were resolved.) or copy it to another workbook.
How?
On the Tools menu, point to Track Changes, and then click Highlight Changes.
In the When box, click All.
Clear the Who and Where check boxes.
Select the List changes on a new sheet check box, and then click OK.
Do one or more of the following:
To print the History worksheet, click Print .
To copy the history to another workbook, select the cells you want to copy, click Copy , switch to another workbook, click where you want the copy to go, and click Paste .
Note You may also want to save or print the current version of the workbook, because this history might not apply to later versions. For example, cell locations, including row numbers, in the copied history may no longer be current.
On the Tools menu, click Share Workbook, and then click the E***ing tab.
Make sure that you are the only person listed in the Who has this workbook open now box.
Clear the Allow changes by more than one user at the same time check box.
When prompted about the effects on other users, click Yes.
On the Tools menu, point to Protection, and then click Unprotect Sheet.
Select the range of cells whose formulas you want to unhide.
On the Format menu, click Cells, and then click the Protection tab.
Clear the Hidden check box.
