MS Excel - VLOOKUP Formula doesnt work for one value - excel

When I run VLOOKUP Formula for 'E' it doesn't find the appropriate value. But all the other formulas gives the correct value as shown in the picture. Can someone help me with this please?

You don't specify a 4th argument in your VLOOKUP function, in which case it defaults to TRUE and expects a lookup range sorted ascending (which you don't have)
Fix by adding a 4th argument of FALSE or 0, e.g. This formula in K2 copied down
=VLOOKUP(J2,M$2:N$7,2,FALSE)
Another option would be to sort your table based on the first column.....but that will also mean you will get an "approximate match" which might not be appropriate in this case, e.g. if you make J2 = "X" then with an approximate match the VLOOKUP will return "WEST"
See excel help on VLOOKUP for parameter explanations

Try copying M3 and pasting values (Alt E-S-V) in J4 and J10.

Excel formula unique list formula not working, if counta = 1

I have the following formula to make a unique list from column plant in table 15:
{=IFERROR(INDEX(Tabel15[Plant];MATCH(0;COUNTIF(Analyses!$Q$2:$Q2;Tabel15[Plant]);0));"")}
This formula is working, but when there is just 1 value in column plant the formula gives a value of 0. This is wrong because it should return the value.
Does anyone know how I can adapt this formula to make it work?
I wanted to change it to this:
{=IF(COUNTA(Tabel15[plant])>0;INDEX(Tabel15[Plant];MATCH(0;COUNTIF(Analyses!$Q$2:$Q2;Tabel15[Plant]);0));Kopie - datablad$G$2)}
But it doesn't work either.
Good mock example. Try and see if this works:
The formula counts the unique cells against another list. The unique list expects to take the first row, no matter what. It also expects you to have more than one value in your duplicate list. If it doesn't you can't compare since it expect duplicates and it throws an error, #N/A. This is mask as blank cell since it's wrapped in IFERROR:
"Unique formula" = IFERROR(INDEX(Tabel15[Plant],MATCH(0,COUNTIF($Q$1:Q2,Tabel15[Plant]), 0)),"")
To solve this we check how many values it exist in our duplicate list:
=IF(COUNTA(Tabel15[Plant])>1,... "Unique formula" ... ,Tabel15[Plant]) //***//
This will give us this result.
Then you probably don't want duplicates...
So we need to check if previous rows contain any of the values the formula would return.
The VLOOKUP formula do that for us, and as lookup value we use the formula above //***// and lookup range will be our current column: $Q$1:Q2. NOTICE this is a dynamic range so Q2 is relative reference (no $).
=IF(ISERROR(VLOOKUP(IF(COUNTA(Tabel15[Plant])>1,IFERROR(INDEX(Tabel15[Plant],MATCH(0,COUNTIF($Q$1:Q2,Tabel15[Plant]), 0)),""),Tabel15[Plant]),$Q$1:Q2,1,FALSE))
So the Final result we need to apply is this in Cell Q3:
=IF(ISERROR(VLOOKUP(IF(COUNTA(Tabel15[Plant])>1,IFERROR(INDEX(Tabel15[Plant],MATCH(0,COUNTIF(Analyses!$Q$1:Q2,Tabel15[Plant]), 0)),""),Tabel15[Plant]),Analyses!$Q$1:Q2,1,FALSE)),IF(COUNTA(Tabel15[Plant])>1,IFERROR(INDEX(Tabel15[Plant],MATCH(0,COUNTIF(Analyses!$Q$1:Q2,Tabel15[Plant]), 0)),""),Tabel15[Plant]),"")
The macro error can be ignored by:
If Not IsError(Sheets("Hulpblad").Range("B6").Value) Then
t = Sheets("Hulpblad").Range("B6").Value
'Code...
End If
there is no problem in your formula, it is just telling that there are blanks in the range, 0 means blank. the formula is treating the blank as a value and also considering it in the unique value calculations.
If you want to remove 0 you can just insert an if over your formula to remove it. like
=if(formula = 0, "", formula)
or in orignal form
=IF( (IFERROR(INDEX(Tabel15[Plant],MATCH(0,COUNTIF(Analyses!$Q$2:$Q2,Tabel15[Plant]),0)),""))=0,"",IFERROR(INDEX(Tabel15[Plant],MATCH(0,COUNTIF(Analyses!$Q$2:$Q2,Tabel15[Plant]),0)),""))
or go in the cell formatting and change the format to display 0 as a dash.
sometimes blank is also used as error checking, you can apply such formulae as well to check how many are blank, maybe that would someday be used to check any data entry problems.

How to combine: INDEX + MATCH + ?VLOOKUP?

I'm having an issue with INDEX + MATCH combination:
=INDEX(ALL!$C$1:$I$1,MATCH(TRUE,ALL!C2:I2<>0,0))
At the moment the aforementioned formula does this job to an extent, where if it finds <>0 value in a row it will return header from this specific column. The issue is that the ROW (as above C2:I2) needs to be specified.
I need to vlookup values in the column "A" in sheet "ALL" and based on that, look at corresponding rows between C:I and if the value in that specific row is <>0 then return heading value.
So, in green I would need a formula to pick up numbers from "Data Source" headings, based on value 1 or any value <>0. I'm guessing it all leads somehow to some sort of "vlookup" hybrid.
Any ideas how to combine vlookup in it?
Thanks
If there can only be one '1' per row, I was thinking of this
=SUMIF(INDEX(B:E,MATCH(G2,A:A,0),0),">0",$B$1:$E$1)
Otherwise if there can be more than one '1'
=INDEX($B$1:$E$1,MATCH(TRUE,INDEX(B:E,MATCH(G2,A:A,0),0)>0,0))
to match the first value greater than zero, in this case entered as an array formula.
A simple =SUMIF() formula will do, no other convoluted INDEX() and MATCH() nested formulas required.
Let's presume we have a data-table that starts at B2 and end at
F6, like this:
So now, to comprehend the solution, here's the syntax of SUMIF() formula (Function):
=SUMIF( range, criteria, [sum_range] )
So, what we want to do is:
go over the range of C3:F3 (and each other respective row)
the criteria to when to sum, is when this range contains 1
and we want to sum_range (sum up) fixed array of numbers, so $C$2:$F$2
So the result is (for row 3):
=SUMIF(C3:F3,1,$C$2:$F$2)
and we drag the formula down, producing expected result:
PS: I think this illustrates the point very well, as to why it's important to declare not only what your formula is doing but also, what you're trying to as in whole as there often is a better (easier) way to implement something, that you might not have thought of.
In other words, follow the Minimal, Complete and Verifiable Example

Search function with list of text values fails

I use formula =SEARCH({"N.","No.","#"},D5) and it fails if doesn't fit first option "N." how can I fix it?
Using =SEARCH({"N.","No.","#"},D5) formula when you will see how the formula calculates the result using Evaluate Formula, you'll notice
evaluates to
That means formula is searching only for "N."
Therefore to search for the existence of "N.","No.","#" in a cell, number of approaches are available like:
1. =IF(COUNT(SEARCH({"N.","No.","#"},D5)),1,"")
This formula will give 1 if any of the string in the cell exists.
2. =SUMPRODUCT(--ISNUMBER(SEARCH(find_text,D5)))>0
This formula will give TRUE if any of the three string exists else FASLE.

Excel SUM and IF combine help

I have two columns of numbers. Both are 1 to 5. I want to count all the cells where the left column value equals the right column value AND the left column value equals a certain value.
I tried this:
=SUM(IF(W2:W13=X2:X13 AND W2:W13=4,1,0))
I've tried pressing Ctrl+Shift+Enter and it adds {} around the formula but that didn't help either.
I think it's the W2:W13 = 4 part that doesn't work
=COUNTIFS(W2:W13,"=4", X2:X13, "=4")
You can use the sumif() function:
SumIf( range, criteria, sum_range )
it will apply the criteria for each row in the range.
Edit: to count the matches, you can use sum_range = 1 or use the Countif() function suggested by Ben in his answer
Have you considered a third column (C) with the formula IF(A1=B1,1,0) and then summing that third column?
I'm not much of an Excel Expert, but didn't they craeted the COUNTIF(range, criteria) function for this?
Add a third column eg Z2:Z13 with this formula: IF(AND(W2=X2; W2=4); 1; 0)
Then sum that one.
I don't have Excel 2007. So here's how you can do it in Excel 2003:
=COUNT(IF((W2:W14=4)*(X2:X14=4),Y2:Y14))
Since you are looking for a specific value and the column next to it to be the same value, you can just compare both columns to the same value.
The trick to get this to work is after entering the formula you need to hit F2 to go into edit mode and then hit CTRL-SHIFT-ENTER which makes this formula an array formula. This will put {} around the entire formula. Without making this an array formula this formula won't work.
I found this information in the Excel help document titled Count how often a value occurs

Excel: VLOOKUP that returns true or false?

In Excel we have the VLOOKUP function that looks for a value in a column in a table and then returns a value from a given column in that table if it finds something. If it doesn't, it produces an error.
Is there a function that just returns true or false depending on if the value was found in a column or not?
You could wrap your VLOOKUP() in an IFERROR()
Edit: before Excel 2007, use =IF(ISERROR()...)
You still have to wrap it in an ISERROR, but you could use MATCH() instead of VLOOKUP():
Returns the relative position of an
item in an array that matches a
specified value in a specified order.
Use MATCH instead of one of the LOOKUP
functions when you need the position
of an item in a range instead of the
item itself.
Here's a complete example, assuming you're looking for the word "key" in a range of cells:
=IF(ISERROR(MATCH("key",A5:A16,FALSE)),"missing","found")
The FALSE is necessary to force an exact match, otherwise it will look for the closest value.
Just use a COUNTIF ! Much faster to write and calculate than the other suggestions.
EDIT:
Say you cell A1 should be 1 if the value of B1 is found in column C and otherwise it should be 2. How would you do that?
I would say if the value of B1 is found in column C, then A1 will be positive, otherwise it will be 0. Thats easily done with formula: =COUNTIF($C$1:$C$15,B1), which means: count the cells in range C1:C15 which are equal to B1.
You can combine COUNTIF with VLOOKUP and IF, and that's MUCH faster than using 2 lookups + ISNA. IF(COUNTIF(..)>0,LOOKUP(..),"Not found")
A bit of Googling will bring you tons of examples.
We've always used an
if(iserror(vlookup,"n/a",vlookup))
Excel 2007 introduced IfError which allows you to do the vlookup and add output in case of error, but that doesn't help you with 2003...
You can use:
=IF(ISERROR(VLOOKUP(lookup value,table array,column no,FALSE)),"FALSE","TRUE")
ISNA is the best function to use. I just did. I wanted all cells whose value was NOT in an array to conditionally format to a certain color.
=ISNA(VLOOKUP($A2,Sheet1!$A:$D,2,FALSE))
