A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
In your "after" illustration I do not see any merging.
I see all blanks in Column A removed and data rows removed.
Have you tried Date>Filter>Advanced Filter for unique values in column A?
Or try this macro.
Sub Delete_Blank_Rows()
Dim RowNdx As Long
Dim Lastrow As Long
Lastrow = Cells(Rows.Count, "A").End(xlUp).Row
For RowNdx = Lastrow To 1 Step -1
If Cells(RowNdx, "A").Value = "" Then
Rows(RowNdx).Delete
End If
Next RowNdx
End Sub
