Finding first blank row, then writing to it

Question

I need to find the first blank row in a workbook and write information to (row, 1) and (row, 2). I think I\'m currently pretty stuck...

Function WriteToMaste         


        

Answer 1

Update

Inspired by Daniel's code above and the fact that this is WAY! more interesting to me now then the actual work I have to do, i created a hopefully full-proof function to find the first blank row in a sheet. Improvements welcome! Otherwise, this is going to my library :) Hopefully others benefit as well.

    Function firstBlankRow(ws As Worksheet) As Long
'returns the row # of the row after the last used row
'Or the first row with no data in it

    Dim rngSearch As Range, cel As Range

    With ws

        Set rngSearch = .UsedRange.Columns(1).Find("") '-> does blank exist in the first column of usedRange

        If Not rngSearch Is Nothing Then

            Set rngSearch = .UsedRange.Columns(1).SpecialCells(xlCellTypeBlanks)

            For Each cel In rngSearch

                If Application.WorksheetFunction.CountA(cel.EntireRow) = 0 Then

                    firstBlankRow = cel.Row
                    Exit For

                End If

            Next

        Else '-> no blanks in first column of used range

            If Application.WorksheetFunction.CountA(Cells(.Rows.Count, 1).EntireRow) = 0 Then '-> is the last row of the sheet blank?

                '-> yeap!, then no blank rows!
                MsgBox "Whoa! All rows in sheet are used. No blank rows exist!"


            Else

                '-> okay, blank row exists
                firstBlankRow = .UsedRange.SpecialCells(xlCellTypeBlanks).Row + 1

            End If

        End If

    End With

End Function

Original Answer

To find the first blank in a sheet, replace this part of your code:

Cells(1, 1).Select
For Each Cell In ws.UsedRange.Cells
    If Cell.Value = "" Then Cell = Num
    MsgBox "Checking cell " & Cell & " for value."
Next

With this code:

With ws

    Dim rngBlanks As Range, cel As Range

    Set rngBlanks = Intersect(.UsedRange, .Columns(1)).Find("")

    If Not rngBlanks Is Nothing Then '-> make sure blank cell exists in first column of usedrange
        '-> find all blank rows in column A within the used range
        Set rngBlanks = Intersect(.UsedRange, .Columns(1)).SpecialCells(xlCellTypeBlanks)

        For Each cel In rngBlanks '-> loop through blanks in column A

            '-> do a countA on the entire row, if it's 0, there is nothing in the row
            If Application.WorksheetFunction.CountA(cel.EntireRow) = 0 Then
                num = cel.Row
                Exit For
            End If

        Next
    Else

        num = usedRange.SpecialCells(xlCellTypeLastCell).Offset(1).Row                 

    End If


End With

Function firstBlankRow() As Long
Dim emptyCells As Boolean

    For Each rowinC In Sheet7.Range("A" & currentEmptyRow & ":A5000")   ' (row,col)

        If rowinC.Value = "" Then
            currentEmptyRow = rowinC.row
            'firstBlankRow = rowinC.row 'define class variable to simplify computing complexity for other functions i.e. no need to call function again
            Exit Function   
        End If
    Next

End Function

If you mean the row number after the last row that is used, you can find it with this:

Dim unusedRow As Long
unusedRow = Cells.SpecialCells(xlCellTypeLastCell).Offset(1, 0).Row

If you mean a row that happens to be blank with data after it... it gets more complicated.

Here's a function I wrote which will give you the actual row number of the first row that is blank for the provided worksheet.

Function firstBlankRow(ws As Worksheet) As Long
'returns the row # of the row after the last used row
'Or the first row with no data in it
    Dim rw As Range
    For Each rw In ws.UsedRange.Rows
        If rw.Address = ws.Range(rw.Address).SpecialCells(xlCellTypeBlanks). _
            Address Then

                firstBlankRow = rw.Row
                Exit For
        End If
    Next
    If firstBlankRow = 0 Then
        firstBlankRow = ws.Cells.SpecialCells(xlCellTypeLastCell). _
                    Offset(1, 0).Row
    End If
End Function

Usage example: firstblankRow(thisworkbook.Sheets(1)) or pass any worksheet.

Edit: As ooo pointed out, this will error if there are no blank cells in your used range.

Answer 4

I know this is an older thread however I needed to write a function that returned the first blank row WITHIN a range. All of the code I found online actually searches the entire row (even the cells outside of the range) for a blank row. Data in ranges outside the search range was triggering a used row. This seemed to me to be a simple solution:

Function FirstBlankRow(ByVal rngToSearch As Range) As Long
   Dim R As Range
   Dim C As Range
   Dim RowIsBlank As Boolean

   For Each R In rngToSearch.Rows
      RowIsBlank = True
      For Each C In R.Cells
         If IsEmpty(C.Value) = False Then RowIsBlank = False
      Next C
      If RowIsBlank Then
         FirstBlankRow = R.Row
         Exit For
      End If
   Next R
End Function

Answer 5

very old thread but .. i was lookin for an "easier"... a smaller code

i honestly dont understand any of the answers above :D - i´m a noob

but this should do the job. (for smaller sheets)

Set objExcel = CreateObject("Excel.Application")
objExcel.Workbooks.Add

reads every cell in col 1 from bottom up and stops at first empty cell

intRow = 1
Do until objExcel.Cells(intRow, 1).Value = ""
   intRow = intRow + 1
Loop

then you can write your info like this

objExcel.Cells(intRow, 1).Value = "first emtpy row, col 1"
objExcel.Cells(intRow, 2).Value = "first emtpy row, col 2"

etc...

and then i recognize its an vba thread ... lol

Answer 6

Very old thread but a simpler take :)

Sub firstBlank(c) 'as letter
    MsgBox (c & Split(Range(c & ":" & c).Find("", LookIn:=xlValues).address, "$")(2))
End Sub
Sub firstBlank(c) 'as number
    cLet = Split(Cells(1, c).address, "$")(1)
    MsgBox (cLet & Split(Range(cLet & ":" & cLet).Find("", LookIn:=xlValues).address, "$")(2))
End Sub
