Many years late  but I just needed to do this and didn t like any of the solutions posted    So I made one up  all thanks to the magic of  SpongeBob rainbow hands gesture   Evaluate      Evaluate  IsError    amp  vSheetName  amp    1 1      Returns TRUE if Sheet does NOT exist  FALSE if sheet DOES exist  You can substitute whatever range you like for  1 1   but I advise against using a single cell  cuz if it contains an error  eg   N A   it will return True

If you are a fan of WorksheetFunction  or you work from a non-English country with a non-English Excel this is a good solution  that works   WorksheetFunction IsErr Evaluate      amp  wsName  amp     A1      Or in a function like this   Function WorksheetExists sName As String  As Boolean     WorksheetExists   Not WorksheetFunction IsErr Evaluate      amp  sName  amp     A1    End Function

Corrected  Without error-handling   Function CheckIfSheetExists SheetName As String  As Boolean       CheckIfSheetExists   False       For Each WS In Worksheets         If SheetName   WS name Then           CheckIfSheetExists   True           Exit Function         End If       Next WS End Function

You don t need error handling in order to accomplish this  All you have to do is iterate over all of the Worksheets and check if the specified name exists   For i   1 To Worksheets Count     If Worksheets i  Name    MySheet  Then         exists   True     End If Next i  If Not exists Then     Worksheets Add Name    MySheet  End If

Put the test in a function and you will be able to reuse it and you have better code readability   Do NOT use the  On Error Resume Next  since it may conflict with other part of your code   Sub DoesTheSheetExists       If SheetExist  SheetName   Then         Debug Print  The Sheet Exists      Else         Debug Print  The Sheet Does NOT Exists      End If End Sub  Function SheetExist strSheetName As String  As Boolean     Dim i As Integer      For i   1 To Worksheets Count         If Worksheets i  Name   strSheetName Then             SheetExist   True             Exit Function         End If     Next i End Function

Without any doubt that the above function can work  I just ended up with the following code which works pretty well   Sub Sheet exist    On Error Resume Next If Sheets     amp  Range  Sheet Name    amp      Is Nothing Then     MsgBox  doesnt exist  Else     MsgBox  exist  End if End sub   Note  Sheets Name is where I ask the user to input the name  so this might not be the same for you

My solution looks much like Tims but also works in case of non-worksheet sheets - charts  Public nbsp Function nbsp SheetExists strSheetName nbsp As nbsp String  nbsp Optional nbsp wbWorkbook nbsp As nbsp Workbook  nbsp As nbsp Boolean  nbsp  nbsp  nbsp  nbsp If nbsp wbWorkbook nbsp Is nbsp Nothing nbsp Then nbsp Set nbsp wbWorkbook nbsp   nbsp ActiveWorkbook nbsp  or ThisWorkbook - whichever appropriate  nbsp  nbsp  nbsp  nbsp Dim nbsp obj nbsp As nbsp Object  nbsp  nbsp  nbsp  nbsp On nbsp Error nbsp GoTo nbsp HandleError  nbsp  nbsp  nbsp  nbsp Set nbsp obj nbsp   nbsp wbWorkbook Sheets strSheetName   nbsp  nbsp  nbsp  nbsp SheetExists nbsp   nbsp True  nbsp  nbsp  nbsp  nbsp Exit nbsp Function HandleError   nbsp  nbsp  nbsp  nbsp SheetExists nbsp   nbsp False End nbsp Function

As checking for members of a collection is a general problem  here is an abstracted version of Tim s answer    Function Contains objCollection As Object  strName as String  As Boolean     Dim o as Object     On Error Resume Next     set o   objCollection strName      Contains    Err Number   0      Err Clear  End Function   This function can be used with any collection like object  Shapes  Range  Names  Workbooks  etc     To check for the existence of a sheet  use If Contains Sheets   SheetName

I came up with an easy way to do it  but I didn t create a new sub for it   Instead  I just  ran a check  within the sub I was working on   Assuming the sheet name we re looking for is  Sheet Exist  and we just want to activate it if found   Dim SheetCounter As Integer  SheetCounter   1  Do Until Sheets SheetCounter  Name    Sheet Exist  Or SheetCounter   Sheets Count   1  SheetCounter   SheetCounter  1 Loop If SheetCounter  lt  Sheets Count   1 Then  Sheets  Sheet Exist   Activate Else  MsgBox  Worksheet   Sheet Exist   was NOT found   End If   I also added a pop-up for when the sheet doesn t exist

Why not just use a small loop to determine whether the named worksheet exists  Say if you were looking for a Worksheet named  Sheet1  in the currently opened workbook   Dim wb as Workbook Dim ws as Worksheet  Set wb   ActiveWorkbook  For Each ws in wb Worksheets      if ws Name    Sheet1  then          Do something here     End if  Next

Some folk dislike this approach because of an  inappropriate  use of error handling  but I think it s considered acceptable in VBA     An alternative approach is to loop though all the sheets until you find a match   Function WorksheetExists shtName As String  Optional wb As Workbook  As Boolean     Dim sht As Worksheet      If wb Is Nothing Then Set wb   ThisWorkbook     On Error Resume Next     Set sht   wb Sheets shtName      On Error GoTo 0     WorksheetExists   Not sht Is Nothing End Function

I actually had a simple way to check if the sheet exists and then execute some instruction    In my case I wanted to delete the sheet and then recreated the same sheet with the same name but the code was interrupted if the program was not able to delete the sheet as it was already deleted  Sub Foo         Application DisplayAlerts   False      On Error GoTo instructions     Sheets  NAME OF THE SHEET   Delete      instructions       Sheets Add After  Sheets Sheets Count      ActiveSheet Name    NAME OF THE SHEET   End Sub

In case anyone wants to avoid VBA and test if a worksheet exists purely within a cell formula  it is possible using the ISREF and INDIRECT functions    ISREF INDIRECT  SheetName A1     This will return TRUE if the workbook contains a sheet called SheetName and FALSE otherwise
