I am trying to build a "data check" type file where a series of macros look at a data set and copy/paste incorrect entries into separate sheets based on various criteria. One of these is looking at if the value in Column A is blank.
Below is the code that I currently have. It only takes the first instance of the blank, and I am trying have it loop to find all the blank values in column A.
Sub copy_blanks() Dim sr As Range Dim blank As Long Dim i As Integer Dim s1 As Worksheet Dim s2 As Worksheet Set s1 = Worksheets("data") Set s2 = Worksheets("No LoadID") lr2 = s2.Cells(Rows.Count, 2).End(xlUp).Row Set sr = Worksheets("data").Range("A:A").Find("") If Not sr Is Nothing Then blank = sr.Row s1.Rows(blank).Copy s2.Cells(lr2 + 1, 1).PasteSpecial xlPasteValues End If End Sub
Have a look at the Range.SpecialCells Method.
You can use
SpecialCells(xlCellTypeBlanks) to find all blank cells in a range.
Dim wsData As Worksheet Set wsData = Worksheets("data") Dim LastDataRow As Range Set LastDataRow = wsData.Cells(Rows.Count, "A").End(xlUp) 'last used cell in column A Dim wsNoID As Worksheet Set wsNoID = Worksheets("No LoadID") Dim BlankCells As Range On Error Resume Next 'next line will throw an error if no blanks are found Set BlankCells = wsData.Range("A1", LastDataRow).SpecialCells(xlCellTypeBlanks) 'find all blank cells in column A until last data row On Error Goto 0 're-activate error messages! If Not BlankCells Is Nothing Then BlankCells.EntireRow.Copy wsNoID.Cells(Rows.Count, 2).End(xlUp).Offset(1, -1).PasteSpecial xlPasteValues Else MsgBox "No blanks found." End If

I prefer using autofilter for this sort of work since that will capture cells that are blank as the result of formulas (and thus contain
"" so they look blank) as blank as well as actually blank cells. Code assumes headers are row 1 and actual data starts in row 2:
Sub copy_blanks() Dim s1 As Worksheet Dim s2 As Worksheet Dim lr2 As Long Set s1 = ActiveWorkbook.Worksheets("data") Set s2 = ActiveWorkbook.Worksheets("No LoadID") lr2 = s2.Cells(s2.Rows.Count, 2).End(xlUp).Row With s1.Range("A1:A" & s1.Cells(s1.Rows.Count, "B").End(xlUp).Row) .AutoFilter 1, "=" .Offset(1).EntireRow.Copy s2.Cells(lr2 + 1, "A").PasteSpecial xlPasteValues Application.CutCopyMode = False .AutoFilter End With End Sub

You question implies you will have more criteria to search for so I decided to keep the loop. You can add more criteria here as you go ~
- Loop through
- If value is blank add the cell to a
Union(collection of cells)
- Once loop is complete, copy the
Unionall at once
This can be improved upon by switching from a
For i loop to a
For Each loop to go through a range. Another way to do this is simply filter
Column A by blanks and copy/paste the visible rows that remain.

- Do you want the whole row to be copied when you have a blank?
- @urdearboy Yes I would like to bring over the whole row, is this still satisfied with the below?
- Yup. Looks like all 3 solutions are grabbing the entire row
- Thank you to everyone for your help! All the answers proved to be useful and I will be able to integrate methods from each into the remainder of the file. Thanks!
- Was going to answer with the
SpecialCellsmethod - would need to add an error handler in case there's no blank cells.
- @DarrenBartrup-Cook Correct. Thank you for pointing out. Fixed it.
- Sorry to stick my oar in again -
Set BlankCells = wsData.Range("A1", LastDataRow).SpecialCells(xlCellTypeBlanks)would throw the error. Could be a rare case of
On Error Resume Next.
- @DarrenBartrup-Cook My bad again :( I'm getting a coffee now. Thanks again!
db.Range("A" & db.Rows.Count).End(xlUp).Offset(1)must be
db.Range("B" & db.Rows.Count).End(xlUp).Offset(1, -1)because there is no data in column A if you copy the rows (only having a blank in A).
