How to some times greater than 24 hours in Excel 2007

November 29, 2009 By admin 6 Comments

To sum times you usually use Excel built-in function SUM. If you have three cells A1, A2 and A3 formatted as time (hh:mm), and you have :

A1 = 02:30

A2 = 10:15

A3 has the formula: =SUM(A1:A2)

then A3 will have the correct values of 12:45.

However if your total times are greater than 24 hours then things get tricky.

If you have :

A1 = 15:30 and A2 = 10:15 then A3 will have 01:45 instead of 25:45. I.e. any hours beyond 24 hours are dropped.

To retain the hours beyond 24, you have two alternatives:

1. If you want to convert the hours beyond 24 into days then use this cell format : dd:hh:mm. The total in the previous example will be 01:01:45 ( 1day , 1 hour and 45 minutes)

2. If you want to keep the hours beyond 24 as is then use this cell format :[h]:mm. The total in the previous example will be 25:45.

In both cases the formula will remain as it is. Only the cell format differs.

Check formula errors in Excel 2007 using IFERROR Function

November 6, 2009 By admin Leave a Comment

One of the newly introduced functions in Excel 2007 is the IFERROR Function. If you are using a formula in a cell, this function allows you to trap formula errors and specify a value to be substituted in the cell in case of an error.

Syntax

IFERROR(value,value_if_error)

Value is the argument (formula) that is checked for an error.

Value_if_error is the value to return if the formula evaluates to an error. The following error types are evaluated: #N/A, #VALUE!, #REF!, #DIV/0!, #NUM!, #NAME?, or #NULL!.

Example:

I have:

  1. Numeric values in cells A1, A2 and B2.
  2. In C2 I have the following formula:

=B2/A2*$A$1

If cell A2 has a value of 0 (zero) the formula will return #DIV/0. To trap this error in Excel 2003 you will use a formula like this:

=IF(ISNUMBER(B2/A2*$A$1);B2/A2*$A$1;0)

The ISNUMBER function, part of the first argument to the IF function; will decide if the value returned from our formula is a number. In this case it will accept the result; otherwise it will substitute a 0. Notice that our formula is supplied twice: as part of the first argument to the IF function, and as a second argument.

The IFERROR function is much simpler.

=IFERROR(B2/A2*$A$1;0)

In this example if there is no error the result of the formula: B2/A2*$A$1 will be returned and accepted, otherwise a 0 will be substituted.
