Excel VBA Loop Rows Until Empty Cell - excel

Question

I have an Excel document with some plain text in a row. The cells in the range A1:A5 contain texts, then a hundred of rows down there's another few rows with text. Cells between are empty.
I've set up a Do Until loop which is supposed to copy cells with text, and then stop when an empty cell appears. My loop counts and copies 136 cells including the 5 with text.
So my question is why?
The bottom line: Hello ends up on line 136, and then there's a huge gap of empty cells until next area with text. Do the 131 white cells contain any hidden formatting causing this?
I've tried "Clear Formats" and "Clear All". I've also tried using vbNullString instead of " ".
Code snippet:
Sub CopyTags_Click()
Dim assets As Workbook, test As Workbook
Dim x As Integer, y As Integer
Set assets = Workbooks.Open("file-path.xlsx")
Set test = Workbooks.Open("File-path.xlsx")
x = 1
y = 1
Do Until assets.Worksheets(1).Range("A" & x) = ""
test.Worksheets(1).Range("A" & y) = assets.Worksheets(1).Range("A" & x)
x = x + 1
y = y + 1
Loop
test.Worksheets(1).Range("A" & x).Value = "Hello"
End Sub

Answer 1

Use a For Next Statement terminating in the last used cell in column A. Only increment y if there has been a value found and transferred and let the For ... Next increment x.
Sub CopyTags_Click()
Dim assets As Workbook, test As Workbook
Dim x As Long, y As Long
Set assets = Workbooks.Open("file-path.xlsx")
Set test = Workbooks.Open("File-path.xlsx")
x = 1
y = 1
with assets.Worksheets(1)
for x = 1 to .cells(rows.count, 1).end(xlup).row
if cbool(len(.Range("A" & x).value2)) then
test.Worksheets(1).Range("A" & y) = assets.Worksheets(1).Range("A" & x)
y = y + 1
end if
next x
test.Worksheets(1).Range("A" & y).Value = "Hello"
end with
End Sub
