Dealing with Long Formulas

Anyone who has been using Excel for any length of time knows that some formulas can get quite long. Excel handles them—as long as they are constructed correctly—but they can be a bear for humans to understand. Even after you develop your own formulas, you may have trouble understanding them weeks or months later.

One way to make formulas a bit easier to understand is to use Alt+Enter in the middle of the formula to "format" how it appears on the screen. Consider, for instance, the following long formula:

=+IF($A2=0,0,IF($B2<4264,0,IF(AND($B2>=4264,$B2<=4895),
(-22.31*$C2/365),IF(AND($B2>=4895,$B2<=32760),($B2*0.093-
476.89)*$C2/365,IF($B2>32760,($B2*0.128-1623.49)*$C2/365)))))

This formula could also be written in the following manner, with Alt+Enter being pressed at the end of each line in the formula:

=+IF($A1=0,0,
IF($B1<4264,0,
IF(AND($B1>=4264,$B1<=4895),(-22.31*$C1/365),
IF(AND($B1>=4895,$B1<=32760),($B1*0.093-476.89)*$C1/365,
IF($B1>32760,($B1*0.128-1623.49)*$C1/365)))))

Now, the broken-up formula appears on five lines, even though it all appears in a single cell. The broken-up formula works just as if it were all on one line.

In addition, if you copy the complete broken-up formula from the Formula bar and paste it into a worksheet, each line in the formula is pasted into a different cell, making it easy to test each part. This is much quicker than copying and pasting parts of the original formula.

Did not work... my formular is 31 lines long - each line 60 characters long.
I'm doing a formula on a serious of date ranges where each date range holds a title. Thus if something is >= <= the date range - the cell result will be the name of of the range.
