Finding first blank row, then writing to it - vba

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 WriteToMaster(num, path) As Boolean
'Declare variables
Dim xlApp As Excel.Application
Dim wb As Workbook
Dim ws As Worksheet
Dim infoLoc As Integer
Set xlApp = New Excel.Application
Set wb = xlApp.Workbooks.Open("PATH OF THE DOC")
Set ws = wb.Worksheets("Sheet1")
'Loop through cells, looking for an empty one, and set that to the Num
Cells(1, 1).Select
For Each Cell In ws.UsedRange.Cells
If Cell.Value = "" Then Cell = Num
MsgBox "Checking cell " & Cell & " for value."
Next
'Save, close, and quit
wb.Save
wb.Close
xlApp.Quit
'Resets the variables
Set ws = Nothing
Set wb = Nothing
Set xlApp = Nothing
Thanks so much for any help.

Answer 1

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 2

I would have done it like this. Short and sweet :)
Sub test()
Dim rngToSearch As Range
Dim FirstBlankCell As Range
Dim firstEmptyRow As Long
Set rngToSearch = Sheet1.Range("A:A")
'Check first cell isn't empty
If IsEmpty(rngToSearch.Cells(1, 1)) Then
firstEmptyRow = rngToSearch.Cells(1, 1).Row
Else
Set FirstBlankCell = rngToSearch.FindNext(After:=rngToSearch.Cells(1, 1))
If Not FirstBlankCell Is Nothing Then
firstEmptyRow = FirstBlankCell.Row
Else
'no empty cell in range searched
End If
End If
End Sub
Updated to check if first row is empty.
Edit: Update to include check if entire row is empty
Option Explicit
Sub test()
Dim rngToSearch As Range
Dim firstblankrownumber As Long
Set rngToSearch = Sheet1.Range("A1:C200")
firstblankrownumber = FirstBlankRow(rngToSearch)
Debug.Print firstblankrownumber
End Sub
Function FirstBlankRow(ByVal rngToSearch As Range, Optional activeCell As Range) As Long
Dim FirstBlankCell As Range
If activeCell Is Nothing Then Set activeCell = rngToSearch.Cells(1, 1)
'Check first cell isn't empty
If WorksheetFunction.CountA(rngToSearch.Cells(1, 1).EntireRow) = 0 Then
FirstBlankRow = rngToSearch.Cells(1, 1).Row
Else
Set FirstBlankCell = rngToSearch.FindNext(After:=activeCell)
If Not FirstBlankCell Is Nothing Then
If WorksheetFunction.CountA(FirstBlankCell.EntireRow) = 0 Then
FirstBlankRow = FirstBlankCell.Row
Else
Set activeCell = FirstBlankCell
FirstBlankRow = FirstBlankRow(rngToSearch, activeCell)
End If
Else
'no empty cell in range searched
End If
End If
End Function

Answer 3

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

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

ActiveSheet.Range("A10000").End(xlup).offset(1,0).Select

Answer 6

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 7

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

Answer 8

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
