I'm trying to conditionally format a column of cells based on whether the combination of two other columns appear in a Table.
Here is a link to the test workbook I am playing with and screenshots below for those that don't like clicking strangers links!

On the far left is an Excel table ([Table1]) that contains a list of valid combinations of [Category] and [Item]
Columns E&F contain some sample data to test against
Column G is the number of matching combinations I expect to return from a COUNTIFS() function
Column H is simply the same formula compared to 0 so I get a boolean result.
The actual formula to get the result shown in Column H is
=COUNTIFS(Table1[Category],"="&E4, Table1[Item],"="&F4)=0
All the above works as expected.
In Column J is just some literal text with conditional formatting. The condition is simply =H4, again this works as expected.
Now to the problem...
I want to avoid having the helper column (H) so I thought I could just use the same formula that I used in column H, as my condition formula.
So, I tried to use this in the conditional formatting formula dialog.
=COUNTIFS(Table1[Category],"="&E4, Table1[Item],"="&F4)=0
and with parantheses
=(COUNTIFS(Table1[Category],"="&E4, Table1[Item],"="&F4)=0)
Unfortunately, this results in the generic "There's a problem with this formula" error message.
If might be that there are some limitations with conditional formatting formulae that I'm not aware of (I'm no Excel guru, I'm a SQL developer really).
BTW: I need to stick with using a table as my real-world scenario is that there will be several tables, all populated from a database via a separate process with lengths varying from 2 or 3 entries to potentially thousands.
I would appreciate any help, even if it's just to say "You can't do this, you'll need to use your helper column..."
Thanks for looking...
I've read this forum for many Excel-related issues over the past 3-4 years, always finding answers when needed... but this time, I'm stumped.
I'm trying to use Conditional Formatting based on a formula to highlight values that are out out of range based on a cell that is a defined distance away. Specifically, the cell I will be attempting to format will be 8 cells to the right of the reference cell. (e.g., comparing R13 to J13, where J13 is the reference value). So the "Lower Spec Limit" is automatically generated from column J to Q, and the user inputs results in columns R to Y.
I would like to accomplish this without having 8 formulas, but so far I have been unable to figure out the right combination of AND/OR statements that will allow me to apply a single formula from row R to Y, where R>J, S>K, T>L, etc. are the conditions to be met.
In a nutshell, the formula I was using was basically:
=OR($R13>$J13,$S13>$K13,$T13>$L13)
Within the Conditional Formatting line. Of course, I then realized that this would format the entire affected range when any condition was met. I also tried to consider whether there was even data in the cell yet, but that got to be a messy way to highlight the entire range again anyway.
From other entries on this site, I've found that I need to:
Avoid INDIRECT references (can be unstable)
Potentially use OFFSET (although I'm unfamiliar within Excel formulas, only used in VBA in the past)
There will be other users for this spreadsheet, so that will have to be a condition.
Is this a feasible task, or would I be better off to have the 8 formulas (which will be 16 if I highlight based on "pass" and "fail" criteria)?
Thank you for your help!
I have a question with regards to conditional formatting which I simply can't seem to solve.
The aim is to format the background color for the left-most cells that are blank up until a cell contains a value - and after this there should be no more formatting in this row. You can see an image of the result I'm hoping for beneath:
So far I've managed to create the conditional formatting of the blank rows, but sadly haven't managed to create the "single-cell" formatting (in yellow) conditional of the sum of all the first cells being = 0.
I've created a formula which actually succeeds in calculating the sum of the previous cells, but this formula includes INDIRECT() which it seems that conditional formatting doesn't allow. At least I'm getting an error starting with the follow (translating the error from Danish to English might not be intuitive):
You cannot use reference operators such as.....
The formula I'm trying is the following:
=AND(SUM(A2:INDIRECT(IF(COLUMN(A2)>=27;CHAR((64-26)+COLUMN(A2))&CHAR((64-26)+COLUMN(A2))&ROW(A2);CHAR((64)+COLUMN(A2))&ROW(A2))))>0;$K2>0)
Where $K2 is the sum of the row.
Is there a way to SUM a range of cells by doing something similar to this:
=SUM(B2:CHAR((64)+COLUMN())&ROW();"")) to dynamically SUM the range from B2 to the current cell? The problem in this case is whether the part CHAR((64)+COLUMN())&ROW();"") can be converted into a legible cell such as B4 to make it work inside the =SUM() formula?
Sadly the =ADDRESS() formula cannot be used (as far as I know) as this will trigger the same error in conditional formatting as well.
For now I would like this to work with the regular Excel conditional formatting, but if anyone have a simple VBA this would also have interest - however, I would by far prefer the regular solution.
The question:
Is there a way to create a formula that doesn't trigger this error - maybe by refrasing the formula or doing something completely else?
It seems to me that this could be handled with a much simpler CFR formula like,
=and(not(sum($a2:a2)), $k2)
Am I missing something?
I'm wondering if anyone knows of a way to get a cell to implement a specific formula based on the contents of another cell.
For example, if one cell contains "general" then a generic sum formula is applied to the cell, though if it contains "conditional" then a countif formula is applied. I can't do this through a general series of chained if statements as there are around 500 formulas that constantly get added and amended and the formula entry area is insufficient to hold them all.
I've figured it out using a UDF and evaluate.
Public Function ev(r As String) As Variant
Application.Volatile (True)
ev = Evaluate(Replace(r, "#", Application.Caller.Row))
End Function
Put a Vlookup inside the ev() call, and have the formulas with # replacing all the row references. Not sure if it is the best way but it got it working.
Can't believe I don't know this, but is there a way to avoid repeating a formula in an if statement if the logical test is dependent on it?
i.e.
=IF((SUMIFS formula)=0,"",SUMIFs formula)
I want to replace that SUMIFS function in the false scenario with something short that will tell it to just programmatically repeat the formula it originally tested for. Repeating the formula twice has to have detrimental effects on processing speed. Negligible, maybe, but want to go for best-practices here. Thanks.
You can force an error like #DIV/0! and then use IFERROR, e.g.
=IFERROR(1/(1/SUMIFS_formula),"")
You can assign a Name to a formula and use the Name..............See:
Assigning a name to a formula
Relevant excerpt -
For example, let's suppose we frequently use a formula like:
=SUM(A1:A100)-SUM(B1:B100) and this resides in A101 and is copied across many columns on row 101. It would be better in this case to
create a custom formula that does this in each cell on row 101. Here
is how;
1) Select cell A101 (this is vital).
2) Go to Insert>Name>Define and
in the "Names in workbook" box type: SalesLessCosts
3) Now click in
the "Refers to" box and type: =SUM(A1:A100)-SUM(B1:B100) then click
Add.
Now you can replace the formula in cell A101 with: =SalesLessCosts.
You can also copy this across row 101 and it will change its relative
references just as the formula =SUM(A1:A100)-SUM(B1:B100) would. The
reason it does this is all down to the fact we selected A101 before
going to Insert>Name>Define and used relative references in
=SUM(A1:A100)-SUM(B1:B100) when we added it to the "Refers to" box.
If all you need to do is hide zeroes, there is an easy way:
Select all cells where you wish to hide zeroes
Go into Custom Number Formatting
Set format to "General;General;"
The custom formatting has a structure of [positive numbers];[negative numbers];[zeroes]
By making the last part blank you are effectively hiding zeroes, but showing everything else.
The advantage over conditional formatting is that you can use this on any background.
A neat trick which I sometimes use is to hide the cell value completely by using a custom format of ";;;". This way you can put images inside the cells, like the conditional formatting ones, and not see the value at all.
Try using the SUBSTITUTE function like this :
=SUBSTITUTE( VLOOKUP( H4; $D$5:$E$8; 2; 0 ); $H$1; $I$1 )
Here is an example:
Here the formula I don't want to repeat twice is the VLOOKUP function.
The result of VLOOKUP is a string found in another table (ex : "Green").
I want to check if that string matches a specific string value in $H$1 (here, "Yellow").
If it does, SUBSTITUTE replaces it with$I$1 (the error string you want. Here, "FORBIDDEN").
If it doesn't, it displays the VLOOKUP result string (the normal authorized output, like "Green").
This is useful for me because my actual formula is quite long, so I don't want to write it twice.
I also dont want to use two different cells, because I'm already applying this formula on 10 columns, meaning I should add an extra 10 columns to make it work.
In some scenarios, MAX() or MIN() can do a wonderful job.
E.g., something like this:
=IF(SUMIFSformula>0,SUMIFSformula, 0)
Can be shortened to this:
=MAX(0,SUMIFSformula)
The LET formula can be used for this exact scenario. You can define the formula as a variable and then within that same cell you can reference the variable in your formula.
The LET formula format looks like this:
=LET(name,name_value,calculation)
SUMIFS Example
Here's how it would work with your SUMIF example so that you don't have to repeat the formula:
In this screenshot we have an array A1:B7. We want to sum the values (Col B) if the name in ColA is "apple".
For this we have a standard SUMIFS formula of
=SUMIFS(B1:B7,A1:A7,"apple")
The formula is showing in E2. The result is shown in E3.
To put this into the IF statement without having to repeat the formula we can use LET as shown in the screenshot.
We create a variable with the SUMIFS formula as the value of that variable. We then write our IF statement using the variable name instead of rewriting the formula multiple times.
=LET(name,name_value,calculation)
Variable name: sumapples
Variable value: SUMIFS(B1:B7,A1:A7,"apple")
Calculation: IF(sumapples=0,"",sumapples)
Put together in the LET function it looks like this:
=LET(sumapples,SUMIFS(B1:B7,A1:B7,"apple"),IF(sumapples=0,"",sumapples))
This LET function can be used in any Excel formula, and is very useful for shortening long formulas that have repetition.
Optional: Extra complexity
If you want to you can get extra complicated by naming multiple variables.
=LET(name,name_value,name2,name_value2,calculation)
Since Excel 2007, the IFERROR statement does what the OP asked. From the help file:
Description:
Returns a value you specify if a formula evaluates to an error; otherwise, returns the result of the formula. [italics mine]
Syntax:
IFERROR(value, value_if_error)
I've since realised that this was already answered by #barry houdini above.
Here is a hack - depending on whether you are just interested in the displayed value, or whether you need to use the value in another formula:
Put your SUMIF formula in the cell (without the IF part)
Create a conditional formatting rule which sets the font color to the background color when the cell value is 0
And hey presto, you get the desired result.
As I said - it's a hack, but it does prevent the double evaluation.
There is no "clean" solution that I am aware of.
