Selecting non-blank cells in Excel with VBA
提问by Tyler Rash
I'm just beginning to dive into VBA and I've hit a bit of a roadblock.
我刚刚开始深入研究 VBA，但遇到了一些障碍。
I have a sheet with 50+ columns, 900+ rows of data. I need to reformat about 10 of those columns and stick them in a new workbook.
我有一张包含 50 多列、900 多行数据的工作表。我需要重新格式化大约 10 个这些列并将它们粘贴到一个新的工作簿中。
How do I programmatically select every non-blank cell in a column of book1, run it through some functions, and drop the results in book2?
如何以编程方式选择 book1 列中的每个非空白单元格，通过一些函数运行它，并将结果放到 book2 中？

The following VBA code should get you started. It will copy all of the data in the original workbook to a new workbook, but it will have added 1 to each value, and all blank cells will have been ignored.
以下 VBA 代码应该可以帮助您入门。它会将原始工作簿中的所有数据复制到新工作簿中，但它会将每个值加 1，并且所有空白单元格都将被忽略。
Option Explicit
Public Sub exportDataToNewBook()
Dim rowIndex As Integer
Dim colIndex As Integer
Dim dataRange As Range
Dim thisBook As Workbook
Dim newBook As Workbook
Dim newRow As Integer
Dim temp
'// set your data range here
Set dataRange = Sheet1.Range("A1:B100")
'// create a new workbook
Set newBook = Excel.Workbooks.Add
'// loop through the data in book1, one column at a time
For colIndex = 1 To dataRange.Columns.Count
newRow = 0
For rowIndex = 1 To dataRange.Rows.Count
With dataRange.Cells(rowIndex, colIndex)
'// ignore empty cells
If .value <> "" Then
newRow = newRow + 1
temp = doSomethingWith(.value)
newBook.ActiveSheet.Cells(newRow, colIndex).value = temp
End If
End With
Next rowIndex
Next colIndex
End Sub
Private Function doSomethingWith(aValue)
'// This is where you would compute a different value
'// for use in the new workbook
'// In this example, I simply add one to it.
aValue = aValue + 1
doSomethingWith = aValue
End Function

I know I'm am very late on this, but here some usefull samples:
我知道我已经很晚了，但这里有一些有用的示例：
'select the used cells in column 3 of worksheet wks
wks.columns(3).SpecialCells(xlCellTypeConstants).Select
or
或者
'change all formulas in col 3 to values
with sheet1.columns(3).SpecialCells(xlCellTypeFormulas)
.value = .value
end with
To find the last used row in column, never rely on LastCell, which is unreliable (it is not reset after deleting data). Instead, I use someting like
要查找列中最后使用的行，永远不要依赖 LastCell，这是不可靠的（删除数据后不会重置）。相反，我使用类似的东西
lngLast = cells(rows.count,3).end(xlUp).row
回答by Jason Williams
If you are looking for the last row of a column, use:
如果您要查找列的最后一行，请使用：
Sub SelectFirstColumn()
SelectEntireColumn (1)
End Sub
Sub SelectSecondColumn()
SelectEntireColumn (2)
End Sub
Sub SelectEntireColumn(columnNumber)
Dim LastRow
Sheets("sheet1").Select
LastRow = ActiveSheet.Columns(columnNumber).SpecialCells(xlLastCell).Row
ActiveSheet.Range(Cells(1, columnNumber), Cells(LastRow, columnNumber)).Select
End Sub
Other commands you will need to get familiar with are copy and paste commands:
您需要熟悉的其他命令是复制和粘贴命令：
Sub CopyOneToTwo()
SelectEntireColumn (1)
Selection.Copy
Sheets("sheet1").Select
ActiveSheet.Range("B1").PasteSpecial Paste:=xlPasteValues
End Sub
Finally, you can reference worksheets in other workbooks by using the following syntax:
最后，您可以使用以下语法引用其他工作簿中的工作表：
Dim book2
Set book2 = Workbooks.Open("C:\book2.xls")
book2.Worksheets("sheet1")

This might be completely off base, but can't you just copy the whole column into a new spreadsheet and then sort the column? I'm assuming that you don't need to maintain the order integrity.
这可能完全偏离基础，但您不能将整列复制到新的电子表格中，然后对列进行排序吗？我假设您不需要维护订单的完整性。
