WR7dFAxOwQ/0.jpg' alt='Excel Vba Update Custom Functions Php' title='Excel Vba Update Custom Functions Php' />The only problem with it is that, when you press F9 or recalculate formulas, the now will be changed to reflect latest date and time. Thus we cannot use NOW as a time stamp. A good alternative although manual is to use keyboard shortcuts CTRL or CTRL to insert current date and time in the active cell. Since this places the value, we dont need to worry even if the date or time changes. But the only issue is, every time you need a time stamp you have to press the 2 keys. A better way to get timestamps in excel is to use a special type of formulas, called as circular formulas. What the heck is a circular formula A circular formula refers to itself or to another cell which in turn refers to this cell. Confused Well, let me give you an example. A2lt 1. A21,A2Now the above formula is normal, but the moment you write it in the cell A2, you have made it a circular formula.

But here is a thing you should be aware of There is a setting called iterations, it tells excel how many times it should run a formula before finalizing the result. This setting wouldnt make any sense in case of regular formulas. But it is very important for circular formulas. If not for this, excel would go in to an infinite loop and stall. Now, by default iterations in formula computation is turned off. That means when you write a circular formula or create a circular reference, excel shows you a message warning you and it doesnt evaluate the formula.

See this The formula itself is very simple IFC3lt ,IFB3,NOW,B3, in cell B3. What it does It checks cell C3 and whenever it is not empty it runs the circular formula IFB3,NOW,B3 which fetches NOW value only if the cell B3 doesnt already have a value, thus serving timestamps. The above formula works only if you have enabled iterative calculation mode as described above. Your thoughts PS Having questions on formulas, try our excel formula helper tool and learn 5.
