Hlookup or Index(match))

=INDEX(Sheet8:Sheet1300!$A$2:$E$3,,MATCH(B9,Sheet8:Sheet1300!$A$1:$E$1,0))
=HLOOKUP(B9,Sheet7:Sheet1300!$B$1:$F$6,2,0)
I have 1300 sheets and one sheet with phone numbers in the B column on sheet7
In B1of all the sheets i have a phone number
and B2 i have the name
I want to return the name for all phone numbers on sheet 7.
I have used both formulas above and they work but only when referencing one sheet.

Since "Sheet7" and "Sheet1300" are just names for the sheets, you can't tell Excel to go "from sheet7 to sheet1300", because what happens if you move Sheet1300 before Sheet7?

The only way I know of to do something like this - looping through sheets - is to use VBA. You might have to use a UDF (User Defined Function) for this.

This is a one shot deal.  It's actually the company cell phone bill that I converted from PDF.  The summary sheet of the bill only has the phone numbers and no names.  I'm trying to cross the phone number on the summary page with the corresponding name.  Since I’m only doing this once the sheet sequence will always remain the same.  If the sheet sequence remains the same 1300 will never be before 7 will a function work.  The reason i ask is I'm terrible at VBA

Here is a user-defined function that will find the first worksheet in which HLOOKUP does not return an error. It will then use that worksheet with the regular HLOOKUP function and return the desired value.

Install the code in a regular module sheet. Use the fx icon to the left of the formula bar, then pick "User defined functions" from the resulting dropdown. You may then pick the HLookup3D function and enter the parameters in the function wizard. The resulting formula should look like:
=HLookup3D(B9,Sheet7:Sheet1300!$B$1:$F$6,2,False)

Function HLookup3D(LookupVal As Variant, LookupTable, nRow As Long, bExactMatch As Variant) As Variant
'Function works just like HLOOKUP function, except can handle 3-D cell range references
'LookupTable may be single sheet or multi-sheet references to a range of cells _
    Enter 3-D ranges just like in a SUM formula:   =HLookup3D("Profits",'Sheet 1:Sheet 3'!A1:H7, 2, False)
'LookupVal may be text or number
'Function returns the value from row nRow on first worksheet where there is a match for LookupVal
'Note: there must be only one HLookup3D function in a formula--the wrong answer will be returned if there is more than one.
Dim cel As Range
Dim iFirstCheck As Integer, iLastCheck As Integer, k As Integer
Dim vResults As Variant, vTable As Variant
Dim wbTable As Workbook
On Error Resume Next
Set cel = Application.Caller
If cel Is Nothing Then
    HLookup3D = "#NoRange"
    Exit Function
End If

vTable = Parse3D(cel.Cells(1), "HLookup3D", 2)
Set wbTable = Workbooks(vTable(0))
iFirstCheck = wbTable.Worksheets(vTable(1)).Index
iLastCheck = wbTable.Worksheets(vTable(2)).Index

If VarType(LookupTable) = 10 Then
    For k = iFirstCheck To iLastCheck
        vResults = Application.HLookup(LookupVal, wbTable.Worksheets(k).Range(vTable(3)), nRow, bExactMatch)
        If Not IsError(vResults) Then Exit For
    Next
Else
    vResults = Application.HLookup(LookupVal, LookupTable, nRow, bExactMatch)

HLookup3D = vResults

HLookup3D-Q27646166.xlsm
For DaFranker's benefit, 3-D range references such as Jenedge73 showed in the original question have long been allowed in certain Excel functions like SUM. The functions that support 3D ranges as arguments are listed in Excel 2003 Help--look for "Refer to the same cell or range on multiple sheets". I don't know where the equivalent article is indexed in Excel 2010 Help. Unfortunately, 3-D range references are not permitted in lookup or conditional functions like COUNTIF, SUMIF, HLOOKUP or VLOOKUP.

I extended the capability of these last four functions so they can handle a 3-D range. Doing so requires the use of VBA code in a user-defined function. Unlike similar-purpose code you may find elsewhere, my user-defined functions accept a real 3-D range. They will update automatically whenever anything changes within that range in any of the worksheets. They will not update if worksheets or cells outside that range are changed.

Brad
I think the VBA approach flexible and therefore superior, and I have a task in my mind to create a DLL using similar functionality that Brad has input to some time back.

However, there are formulaic approaches, just for the record, though I start to get a bit cross-sighted, here's one example...

Actually, I believe you can use these conditional functions - or simulate them, anyway.  Here's one example using COUNTIF to count the occurrences of the value "5" in A2:E3 of sheets 7:1300 (well, actually SUMPRODUCT to simulate COUNTIF):

Of course, this depends on the sheets actually existing, as opposed to having a starting/ending sheet as your VBA code would entertain, but it can be done.

=SUMPRODUCT(COUNTIF(INDIRECT("'Sheet"&ROW($7:$1300)&"'!$A2:$E3"),"5"))


INDEX/MATCH/etc. MAY also be conducted in a like manner.

Dave
Dave,
The return value is supposed to be a name, so you need HLOOKUP, INDEX & MATCH, etc.

For example:
=HLOOKUP(B9,INDIRECT("Sheet" & SUMPRODUCT(ROW($7:$1300)*COUNTIF(INDIRECT("Sheet" & ROW($7:$1300) & "!B1:F1"),B9)) & "!B1:F2"),2,FALSE)

Major limitation: the formula will fail if there is more than one occurrence of the phone number in Sheet7:Sheet1300!B1:F1

I've revised my sample workbook to include a variation on the above formula to prove that the approach works.

Brad
HLookup3D-Q27646166.xlsm
I can avoid the major limitation mentioned in my last comment by using MAX in an array-entered formula. Now the only glitch occurs if the phone number is mentioned more than once on the same worksheet.
=HLOOKUP(B9,INDIRECT("Sheet" & MAX(ROW($7:$1300)*COUNTIF(INDIRECT("Sheet" & ROW($7:$1300) & "!B1:F1"),B9)) & "!B1:F2"),2,FALSE)

To array-enter a formula:
1) Select the cell and click in the formula bar
2) Hold the Control and Shift keys down
3) Hit the Enter key
4) Release all three keys. Excel should respond by putting curly braces { } surrounding your formula.
I knew if anyone could make that approach work, you could.  About all I've gotten it to do up to this point is count, lol.

You and barry are the best.

Dave
Array-entered formula that eliminates even the restriction on not having duplicate phone numbers on the same worksheet:
=HLOOKUP(B9,INDIRECT("Sheet" & MAX(ROW($7:$1300)*(COUNTIF(INDIRECT("Sheet" & ROW($7:$1300) & "!B1:F1"),B9)>0)) & "!B1:F2"),2,FALSE)

Note that HLookup3D returns the first name corresponding to the first worksheet with a matching phone number, while the array formula above returns the first name corresponding to the last worksheet containing that phone number.

And as Dave mentioned, the formula will blow up if even one worksheet in the series Sheet7 through Sheet1300 is missing.

Brad
Brad - I tried last night to create the array of sheets in another cell, and could not get the INDIRECT to work (returning the array) as it did when ROW($7:$1300) was embedded in the formula.  If that's possible, then there could be a bit more flexibility in the formulaic approach.

WOW! Thanks man
Jenedge73,
I'd be interested to know how long it takes for the INDIRECT formula to work in your real workbook with all the phone numbers compared to the HLookup3D function. Could you please post back in this same question with the results?

You can trigger the recalculation by selecting the column of cells with the formula, then replacing all the = sign with another = sign.

Thanks!

Brad
I have great interest in that response as well.

Thanks for posting, Jenedge73!

Dave
It's actualy pretty quick less than two minutes
Jenedge73,
INDIRECT is a volatile function. Any formula containing INDIRECT will recalculate whenever any change is made to an open workbook. So if it takes two minutes to calculate the first time, it should take another two minutes when you type your name in a blank cell. The only way of avoiding this recalc time is to replace all the INDIRECT formulas with the values they returned (Edit...Copy followed by Edit...Paste Special...Values).

The user-defined function, on the other hand, is non-volatile. It will only recalculate when one of its arguments changes value. Furthermore, it quits searching once it finds an answer. So I think it might to be faster than the INDIRECT formula.

Both Dave and I are curious about the speed comparison because we'd like to offer good advice in the future regarding this type of problem. Especially if one way is clearly faster than the other.

Brad
The Hlookup3d is tons more efficient.  It does calculate quicker and doesn’t keep recalculating.
Good to know

Thanks
Jenedge73,
Thanks for being such a good sport and performing the test both ways.

While it might not make any real difference in a one-off question such as you were trying to solve, the next person may need to be making a number of adjustments to the workbook after getting the "answer."  In such cases, Dave and I now know that we should be pushing the HLookup3D approach.
