Matching two columns in one sheet to two columns in another - excel

I need to assign a status to a row based on a VLOOKUP query between two worksheets. The problem is that the identifier is not always unique. However, the identifier + a date value should be unique. I wanted to use:
=VLOOKUP(A3&H3,'OtherSheet'!D:E,1,FALSE)
with A3 being the identifier and H3 being the corresponding date. D in the other sheet is the identifier and E is the date column. However, I keep getting #N/A.
Does this mean that there are no matches with the "identifier+date" or is Excel looking for "identifier+date" in either column D or E? If the latter is true, how can I let Excel concatenate D and E when matching to the search pattern?

There's work around without using CTRL+Shift+Enter.
Use this formula that will match A3 in D column of othersheet and H3 with the date in column E of the othersheet.
=INDEX(OtherSheet!F:F,MATCH(1,INDEX((OtherSheet!D:D=A3)*(OtherSheet!E:E=H3),),0))
The formula will return data from F column of OtherSheet.
You can modify the range OtherSheet!F:F as appropriate.

That formula is looking to find A3 concatenated with H3 (identifier&date) in OtherSheet ColumnD that contains only identifiers, so will inevitably fail. Yes, Excel is looking for “identifier+date” in column D.
Excel will happily concatenate A3 with H3 ‘on the fly’ (within a formula) but will not so happily concatenate OtherSheet ColumnD and ColumnE values in the same way. The conventional solution, because usually simplest in a case like this, is to prepare for the VLOOKUP by adding a helper column that concatenates the D and E values while preserving these in the same row as the value sought.
Because VLOOKUP will only look to the right this is usually a column that is added to the left of the value being searched for, so say either in C or by insertion of a column immediately to the right of C. However, since you are only checking a single column the location is not critical. You might add this (in OtherSheet) as ColumnZ, with a formula such as:
=D2&E2
copied down to suit*. Again because you are only checking a single column it does not matter which row such a formula is placed in.
However, because only checking whether A3&H3 exists in OtherSheet a simple alternative may be to apply COUNTIFS:
=COUNTIFS(OtherSheet!D:D,A3,OtherSheet!E:E,H3)
Any result other than 0 from this should indicate that the combination being tested for exists in OtherSheet – without need for a helper column.
* Depending on the format of your identifiers it is possible that concatenation may introduce ambiguity. For example ID90 concatenated with 11/1/15 may not be distinguishable from ID901 concatenated with 1/1/15, so it may be advisable if taking this approach to introduce a delimiter, in both the VLOOKUP formula (say A3&"|"&H3 rather than just A3&H3) and therefore also in the helper column, say =D2&"|"&E2.

You likely would want to use Index/Match instead. Vlookup is tricky when it comes to searches for multiple things. Here's the way you would use Index/Match:
Without knowing how your spreadsheet is set up, here's how you could do it:
If I understand correctly, you want to use A3 to find the match in OtherSheet!D, and H3's match in OtherSheet!E. Index match is perfect for this. Instead of vLookup, use
=Index(OtherSheet!D:D&","&Text(OtherSheet!E:E,"mm-dd-yyyy"),Match(A3&H3,OtherSheet!D&OtherSheet!E,0)), and enter with CTRL+SHIFT+ENTER.
What the Index() will return is the concatenated Identifier and Date, separated with a comma. If, though, you have a table like this:
That index/match formula will return "Batman". The index to return is the named range G2:G5. You're looking for a match on A1 (the Identifier) and B1 (the Date), then you're searching for (in the order you just put) the Identifier to be in the range E2:E5, and the Date to be in F2:F5. When there's a match for both, it returns the name in G2:G5.
Here's a link to a site on using Index/Match, and another and its advantages over vlookup.

"The range where the lookup value is located. Remember that the lookup value should always be in the first column in the range for VLOOKUP to work correctly. For example, if your lookup value is in cell C2 then your range should start with C."
But sometimes I want to be able to do dual-direction lookups. Ie, lookup using a key in column A to get the value in column B AND at the same time, in other formulas, lookup the value in B to get the value in A.
The only way I know is to add a column C which mirrors A, then use AB for the first lookup, and BC for the second lookup. But there has to be some cleaner solution. Is there some way to force VLOOKUP to use a different column other than the first one to find the key value, or is there a different function that would allow the equivalent?
As a side note, I am asking about Excel, but I actually use LibreOffice. Presumably the functions should be identical, but an answer that also works in LibreOffice would be preferable.
INDEX/MATCH will do it any direction of search.
So for your example of B --> A:
=INDEX(A:A,MATCH(yourCriteria,B:B,0))
The MATCH returns the row number of the match. The third Criterion of 0 is optional. The 0 is the same as FALSE for the forth criterion of VLOOKUP, in that it looks for an exact match.
The default is 1 with the data sorted it will return the match that is less than or equal to the criteria Like VLOOKUP's TRUE.
From that the INDEX finds and returns the correct value.
With the introduction of the Dynamic Array formula XLOOKUP we can use:
=XLOOKUP(yourCriteria,B:B,A:A,"",0)

Excel VBA/Formula to find a cell that includes search term?

I was not sure how to really create the question...
But the problem I am having is this: I have a list (in rows) that relate to a regulatory document, and after trying to create some sort of for loop or elaborate VLookUp/Index formula, I'm requesting help.
For example:
Now I want to use the rows to find the corresponding section in the document. I've already extracted and formatted the compliance document so it is in excel format.
So what I really need is this: a formula or VBA script that can
1. take the compliance number (for example 1A-1 which exist in Cell A3) and go find a cell (in single column D) that has JUST 1A-1, not 1A-1.1, not 1A-1.1.2, etc. and return it to the adjacent cell to 1A-1, for example.
Many thanks ahead of time... I am so lost!! :/
VLOOKUP vs INDEX/MATCH
You can do the 'lookup' two ways (that I'm aware of):
Using VLOOKUP:
The B3 cell contains your formula
=IF(ISERROR(VLOOKUP(A3,C:D,2,FALSE)),"",VLOOKUP(A3,C:D,2,FALSE))
where 'FALSE' is indicating there has to be an exact match and the data doesn't have to be sorted.
Using INDEX with MATCH:
The F3 cell contains the Index/Match formula
=IF(ISERROR(MATCH(A3,C:C,0)),"",INDEX(D:D,MATCH(A3,C:C,0)))
where '0' is indicating there has to be an exact match and the data doesn't have to be sorted.
INDEX/MATCH preferable!?
The MATCH function finds the position (row number if whole column is used) of the found match. This way (there's another) of using the INDEX function uses exactly this found match to return a cell's value in that position (row) in ANY specified column range (column). So they are the ideal combination.
With the VLOOKUP function you have to additionally specify the column index (range_lookup) of a range which could get complicated when the columns aren't adjacent as in this case. Most importantly, the function doesn't work if the lookup data is to the right of the match data.
VLOOKUP NOT WORKING! INDEX/MATCH STILL WORKING!
try this formula
The formula in cells
B2: =INDEX(E:E,MATCH(A2,F:F,0))
C2: =INDEX(G:G,MATCH(A2,F:F,0))
MATCH(A2,F:F,0) is finding Cell A2 in column F (0 means it will find
exact match) and will return the first row number when it would find that
INDEX(E:E,MATCH(A2,F:F,0)) will return contents of column E where row number is returned by the Match formula

Excel VLOOKUP where the key is not in the first column

using if search formula in excel

is there a way to combine a search formula with a lookup or possibly use an if then statement. I think I have the first part working but need help with the second part. I am looking for values in column A and based on the values found in column A, I need to look at values in other columns and return the value found in that column.
Example, if column A contains value "car", I need to look at column B and return the value found in column B in column F , if column A contain value "boat", I need to look at column C and return the value found in column C in column F.
Any help would be much appreciated
Assuming that you have a list of possible values: car, boat, bike, plane, ... that would lead you to look for values in column B, C, D, E, ... I suggest you do the following:
Define the name "transportation" (whatever name you want to call it) with the types of transportation you need - for example, ={"car", "bike", "tram", "bus", "boat"} . On Office for Mac 2011 you do this with Insert->Name->Define... - for other versions of Excel it might be different (but note - you actually type both the = sign and the {} curly braces around the list of values you want to be able to look up). Put them in the order of the columns that you want.
For every lookup that you need, you can now write
=INDEX(B4:F4,0,MATCH(A4,transportation,0))
if the value (car, bus etc) is in cell A4, and you want to look up the corresponding value from columns B through F.
If you have column headings above your columns, you can use the MATCH function without having to define a name explicitly. For example, if you have car, bike, tram etc in cells B1:F1, you can use
=INDEX(B4:F4, 0, MATCH(A4, $B$1:$F$1, 0))
to do the lookup.
Explanation: the MATCH function (with third parameter 0) looks for the exact match for the first value (in cell A4 in this case) in the array that is the second parameter (either the named range, or the range with fixed address that I gave above). You then look up the appropriate cell using the INDEX function which gives you an offset into the range (B4:B4 in the above) of cells where you need to do the lookup.
I trust you can adapt this to your exact needs. Ask if you need more help.
The following formula is the simplest way I can think to do it:
In cell F1, the formula would be
=IF(A1="car",B1,C1)
This is case insensitive, so it should work for CAR as well. But bear in mind that this has the downside that with a formula this simple, ANY value in A1 other than "car" (not just "boat") would lead to the other value ending up in the F column.
=IF(A1="car",B1,IF(A1="boat",C1,""))
