testing for non-empty cells
I need to test an entire column to see if there are any non-blank cells in
the column. I've tried writing an expression using CountA(), but I can't get it to work. Can anyone tell me how I could test, say, Column C, to see if there are any blank cells in that column? Thank you in advance. Paul |

Hello Paul
Dim intNo as Integer intNo = Application.CountBlank(ActiveWorkbook.Worksheets(1 ).Range("C:C")) Heiko :-) "Paul James" wrote: I need to test an entire column to see if there are any non-blank cells in the column.

testing for non-empty cells
Paul,
This is one way to do it. I've used a range in the function to ensure that if this is used as a UDF it can reference another sheet if needed. If your in XL97 you'll need to change the line that sets lrow to 16384 (or whatever the max rows is). Public Function IsColumnEmpty(rngTest As Range) As Boolean Dim lRow As Long Dim nCol As Integer nCol = rngTest.Column With rngTest.Parent lRow = .Cells(65536, nCol).End(xlUp).Row If lRow = 1 And IsEmpty(.Cells(lRow, nCol).Value) Then _ IsColumnEmpty = True End With End Function Robin Hammond www.enhanceddatasystems.com Check out our XspandXL add-in "Paul James" wrote in message news:ULJWa.46245$uu5.5082@sccrnsc04...

testing for non-empty cells
Paul,
Doesn't =COUNTA(C:C) tell you if there are some non-blank cells. It picks up formulae and values. The number of rows is 65536 (97 and above), so if it's less than that number there are balnsk =IF(COUNTA(C:C)<65536,"you have blanks","no blanks") -- HTH Bob Phillips "Paul James" wrote in message news:ULJWa.46245$uu5.5082@sccrnsc04...

or just change it to:
Public Function IsColumnEmpty(rngTest As Range) As Boolean Dim lRow As Long Dim nCol As Integer nCol = rngTest.Column With rngTest.Parent lRow = .Cells(rows.count, nCol).End(xlUp).Row If lRow = 1 And IsEmpty(.Cells(1, nCol).Value) Then _ IsColumnEmpty = True End With End Function But if using as a UDF, might as well just use the countA function directly. Regards, Tom Ogilvy Heiko wrote in message ... Dear Robin, thats good too but only if one is using <= Excel 5 he has to modify the maximum Rowcount.

=if(countA(C:C)=0,"All Blank","Blanks: "&rows(C:C)-CountA(C:C))
if you want to find blanks only up to the last used cell =IF(COUNTA(C:C)=0,"All Blank","Blanks: "&MATCH(9.99999999999999E+307,C:C)-COUNTA(C:C)) if only numeric values are contained in column C or for only non-numeric entries: =IF(COUNTA(C:C)=0,"All Blank","Blanks: "&MATCH(REPT("Z",255),C:C)-COUNTA(C:C)) Actually, the restriction is only to the type of data in the last populated cell. -- Regards, Tom Ogilvy Paul James wrote in message news:ULJWa.46245$uu5.5082@sccrnsc04...
