Is A Single Formula Better Than Intermediate Calculations?
Feb 2, 2010
I come from a (procedural) programming background, where we perform operations step by step. I tend to use intermediate calculation columns, with only 1 or 2 calculations per formula, or, failing that, use a UDF. I find this easier to debug and maintain.
The solutions I see tend to give the result in one formula. This reminds me of the functional progamming languages I used years ago. I'd like your opinions on what is best-practice, or common practice, in relation to constructing formulas, so that I can improve my development.

I'm trying to condense a table of calculations down to a single array formula, but am getting stuck on one piece of it.
The table data is very simple, and can be in just two columns:
1, value
2, value
3, value
4, value
5, value
Where 1 thru 5 are time periods, and values are various numbers.
I want to perform the GammaDist function on each value. It requires a time period input, and in this case it is the 1 thru 5 in the table. So at the end of period 5, the formula for the first value would be
=Gammadist(5,x,y,TRUE) (x,y values not important here)
and the formula for the second value would be:
=Gammadist(4,x,y,TRUE)
The only thing that changes is the period number.
So, my goal is to write an array formula that will sum the GammaDist for each of the 5 rows, for all timeperiods (which is 5 in this case)
I can get this far:
={SUM(B1:B5*GAMMADIST(ROWS(1:5)-1,C1,C2,TRUE))}
But this passes 1 thru 5 to all rows, I only want 1 thru 5 passed to row 1, 1 to 4 passed to row 2, etc.

Column A has (say) 5 cells.
A1 = R, A2 = R, A3 = O, A4 = R, A5 = O
I need to count the Rs and Os separately
So column B ends up with B1 = 1R, B2 = 2R, B3 = 1O, B4 = 3R, B5 = 2O or at least B1 = 1, B2 = 2, B3 = 1, B4 = 3, B5 = 2 so i can later say =B1&A1 to merge them into what i need.

Is it posible to do 3 seperate calculations in a single cell and desplay those results? For example in a single cell: A1+A2 | A3+A4 | A5+A6|
Where:
A1 = 1
A2 = 2
A3 = 3
A4 = 4
A5 = 5
A6 = 6
Results Display: 3,7,11.

I'm looking to do some simple maths with ranges in Excel but I'd like a way to be able to input all these formulas automatically although I am pretty sure a single formula per column could do it all automatically. I've got to put the sums in AD to AF on the first line of each location, but the maths is for the entire location's range.

I have A1 that contain numbers, B1 that contain number, and i want to multiply those 2 and at the end of result i want to add zeros on front. Let me give you an example:
A1 field has data :00.375B2 has data: 6.49 C1 has the multiply result of A1+B1: 2.43 (But i want when the calculation is done and have the result 2.4 to add 2 zeros on front and become: 002.43 or if the result is for example: 65.20 to add 1 zero on front and become 065.20 , and if the result is 102.20 do not add anything on front.
So in total i need to have the 5 digits of number.

I'm trying to do two things:
1. I'm trying to show the formula of specific cells in the work sheet. So far I've only found out how to show formulas on the entire worksheet. I imagine there has to be some way of me doing this without using macros.
2. Here's the doozy. What I'm trying to do is use the base code for a formula that is stored in one cell (Formula Page: B5:B7) and apply it to other cells (Calc Page: C4:C6). In other words, I want to apply the cell formula from B5:B7 to the cells C4:C6 and use them to calculate the TOTAL COST. I want it so that whenever I manipulate cells B5:B7, they are also appropriately manipulated in C4:C6.
Please see attached for reference. Attachment 33077

I have a formula that will be used by others to obtain a certain result by altering a number in the formula. What I would like to do is make that number obvious as the one that can be changed. The formula reads - "=(M48+P48+Q48)*0.08453-(((J48+K48)*$K$4)*0.1)" -what I would like to do is color the 0.08453 in the Formula Bar so it stands out.

I have the following formula in 220 cells in a workbook:
=( SUMPRODUCT(('General Journal'!$C$1:$C$44995>=$D$3)*('General Journal'!$C$1:$C$44995<=$E$3)*('General Journal'!$H$1:$H$44995=$A5),'General Journal'!$I$1:$I$44995))+(SUMPRODUCT(('General Journal'!$C$1:$C$44995>=$D$3)*('General Journal'!$C$1:$C$44995<=$E$3)*('General Journal'!$J$1:$J$44995=$A5),'General Journal'!$K$1:$K$44995))+(SUMPRODUCT(('General Journal'!$C$1:$C$44995>=$D$3)*('General Journal'!$C$1:$C$44995<=$E$3)*('General Journal'!$L$1:$L$44995=$A5),'General Journal'!$M$1:$M$44995))
Where D3 is a starting date, E3 is a closing date, and A5 is a sorting code. It looks at my general journal and looks for all the entries between the two dates, and then sums up all the entries linked to the sorting code in A5. The sorting code is in column H, and the amount to sum is in column I, and this is repeated 3 times.
You are already probably signering at how long I must have to wait while excel calculates all these formulas (* 220). I have resorted to a macro that turns caluculation to manual when I open this workbook, and back to auto when it closes.

I have used the code for formatting: http://www.ozgrid.com/VBA/excel-cond...ting-limit.htm. This works fine when typing in the numbers manualy but if I have a formula (eg:A1=b1+c1) and a1 = 15 nothing happens. Is there an update button or a better way to do this?

I have 2 formulas which I want to combine into a single formula.
Both are correct and work in isolation, but when I attempt to combine them, the syntax is incorrect.
Here is the first:
=IF($C$31="YES","YES","NO")
The formula is dependent on a single user selection from a drop down list. If the user selects YES, the cell in which the formula resides displays YES, otherwise NO.Here is the second:
=IF(AND(OR($C$9="YES",$C$13="YES",$C$15="YES",$C$21="YES",$C$25="YES"),....

I am trying to incorporate several IF statements into a single formula:
=IF(AB5<20,"LR",IF(AND(AB5<30,AB5>25),"C",IF(T5<>"","CLEAR",IF(AND(AB5<240,AB5>40,AA5=1),"B-T1-F10",""))))
What I am trying to achieve with this formula is:
- insert LR if AB5 is less than 20;
- insert C if AB5 is less than 30 but more than 25;
- if neither of the above is true, insert CLEAR if T5 contains something and if not insert B-T1-F10 if AB5 is between 240 and 40 and AA5 = 1.
The problem I have is that the B-T1-F10 is not being inserted where the other criteria are not met so I think I have not integrated the statements correctly?

I am creating a spreadsheet for inventory use. I want to have a running total in (1) cell based upon a new/different number being entered into a different cell.
Column B, Row 1 (This will be a new/different number entered every day - inventory in or out, so positive or negative number) Column D, Row 1 (This will be a running total based on numbers inserted in previous 2 columns)
Basically what I have is a key inventory. So there is column A with key number, B should be keys IN, C should be keys OUT, or ideally B would be IN and OUT meaning, for inventory IN input a positive number and for inventory OUT input a negative number, and D Should be total.
Column E represents number of keys currently in the inventory. I was going to hide the current inventory column so all you see is IN/OUT and total. So what I need is to be able to just come in and type in a number in the IN and/or OUT column, without having to add/subtract it with the number already in that column.
Bottom line, I'd like to be able to use IN and/or OUT columns to just type in numbers as they come and not have to worry about what's already in those columns and get correct total number.

I'd like to apply multiple formula to a set of cells on a summary page. My summary page also contains 3 variable dropdowns, and I'd like to display data based on the text selected in those dropdowns (pulling data from 2nd tab "Variables")
The following formula works in the first instance:
=IF(AND(H4="Product Type A1", H6="External", H8="Existing"), Variables!C4, 0)
What I'm struggling to do is add additional formula to the same cell in order to deal with the remaining eventualities of the drop down variables:
Variable 1:
Product Type A1
Product Type A2
Product Type B1
Product Type B2
Variable 2:
Internal
External
Variable 3:
Existing
New
Or am I better using a VLOOKUP or something?

I've got a "Date" Column which has every day of every month, and next to that several columns with different types of data to correspond to a particular date.
To simplify this (because there are TONS of dates), I've made another "Date" column that displays only every 5th day. Now what I'd like to do of course is average the corresponding data over five days.
I don't know how to write a single formula that I can copy down that will do this.
I've attached a sample spreadsheet with only one month's data, the stuff I need a formula / code for is in red

I'm looking for a way for Excel to combine formulas together into a more compact form for me.
Attached is a very simple version of what I want, my actual formulas are very complex but I'd still like a way to have them automatically combined into a single cell.
Alternatively, what is a good way to break down a very complicated one-cell formula and still keep things organized?
Here is the one-cell version of a formula I work with.
[Code] .......
That formula is difficult to work with in one cell, so on another sheet I have it broken down into parts so that if one part isn't doing what I want I can change it. This takes up a LOT of space because of the other steps I do (the above formula is just one step) and I'd like to combine it together.

For now, I have :

I need a function that will use a column of text values and test these values
to see if one or more of the values exist in a single cell. If it does I need
the function to return true or false.
Ie. cell A1 contains the text "Jim Smith" the B column contains the test
names (column of test values ) ie. B1 is "bill" B2 is "fred" B3 is "jim".
Because Jim is in the cell A1 I would need the function in C1 to return the
value "true". If A1 contained the text "bob smith" then function in C1 would
return the value "false".
