How to transpose different sized rows into one column - excel

Question

I'm pretty new to Excel VBA and I am currently trying to take data from multiple rows and transpose it into a single column. I know where the first cell of the data will begin, but that's all I know. Each row of data is a different sized row, and there can be a varying number of columns also.
So my current method is using a sort of transpose where I just select a very large range (in hopes that it captures all my data) and then transposing it. It does work, albeit pretty slow, and it also includes all the blanks in my range also.
Sub transpose()
Dim InputRange As Range
Dim OutputCell As Range
Set InputRange = Sheets("Sheet1").Range("P1:AC100")
'output will begin at this cell and continue down.
Set OutputCell = Sheets("Sheet1").Range("A1")
For Each cll In InputRange
OutputCell.Value = cll.Value
Set OutputCell = OutputCell.Offset(1, 0)
Next
End Sub
The current method isn't the worst, but I'm sure there are better methods that are quicker and ignore blanks. I'm not sure if an actual transpose is the best way, or perhaps using some sort of loop method. The data is usually contained within 200 rows, and 10 columns if that helps in deciding a method (maybe looping might be quick enough). Any help would be appreciated!
Edit
I have found a method of ignoring the blanks:
For Each cll In InputRange
If Not IsEmpty(cll.Value) Then
OutputCell.Value = cll.Value
Set OutputCell = OutputCell.Offset(1, 0)
End If
Next

This 'snake' method works fine for me.
Sub Snake()
Dim N As Long, i As Long, K As Long, j As Long
Dim sh1 As Worksheet, sh2 As Worksheet
K = 1
Set sh1 = Sheets("Sheet1")
Set sh2 = Sheets("Sheet2")
N = sh1.Cells(Rows.Count, "A").End(xlUp).Row
For i = 1 To N
For j = 1 To Columns.Count
If sh1.Cells(i, j) <> "" Then
sh2.Cells(K, 1).Value = sh1.Cells(i, j).Value
K = K + 1
Else
Exit For
End If
Next j
Next i
End Sub

One thing you could do is instead of looping the entire range just loop the SpecialCells.
Depending on what the content is of your inputRange then you can choose which XlCellType to use.
If it is just hardcoded values then xlCellTypeConstants would work fine for you.
Alternatively, you might be looking at formulas, in which case you would want to use xlCellTypeFormulas.You can also do a Union if you need both.
Here is an example using just xlCellTypeConstants
Sub transposes()
' Example just for hardcoded data
Dim inputRange As Range
Set inputRange = Sheets("Sheet1").Range("P1:AC100").SpecialCells(xlCellTypeConstants)
Dim outputCell As Range
Set outputCell = Sheets("Sheet1").Range("A1")
Dim cell As Range
For Each cell In inputRange
Dim offset As Long
outputCell.offset(offset).Value = cell.Value
offset = offset + 1
Next cell
End Sub
