我试图导入和排序从大的Excel报表数据为使用Excel 2007 VBA的新文件。我想出了两种方法，到目前为止这样做的：
Public Sub GetData()
Dim FilePath As String
FilePath = "D:\File_Test.xlsx"
Workbooks.OpenText Filename:=FilePath, FieldInfo:=Array(Array(2, 2))
ActiveWorkbook.Sheets(1).Select
End Sub
Private Sub PopArray() 'Uses ADO to populate an array that will be used to sort data
Dim dbConnection As ADODB.Connection, rs As ADODB.Recordset
Dim Getvalue, SourceRange, SourceFile, dbConnectionString As String
SourceFile = "D:\File_Test.xlsx"
SourceRange = "B1:Z180000"
dbConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;" & _
"Data Source=" & SourceFile & ";" & _
"Extended Properties=""Excel 12.0 Xml;HDR=No"";"
Set dbConnection = New ADODB.Connection
dbConnection.Open dbConnectionString 'open the database connection
Set rs = dbConnection.Execute("SELECT * FROM [" & SourceRange & "]")
Arr = rs.GetRows
UpBound = UBound(Arr, 2)
rs.Close
End Sub
所使用的测试文件大约有65000条记录进行排序通过（约我最终会使用它的三分之一）。我是那种失望的是，ADO版本只比开放工作进行稍微好一些（〜44秒VS〜40秒跑完时间）。我想知道是否有某种方式来提高ADO导入方法（或一个完全不同的方法 - ExecuteExcel4Macro可能 - 如果有的话），这将提高我的速度。我能想到的唯一的事情是，我使用"B1:Z180000"作为我SourceRange的，然后由设置Arr = rs.GetRows准确反映记录总数截断的最大射程。如果这是什么原因造成的慢了下来，我不知道我怎么会去寻找有多少行的表。
编辑 - 我使用的范围（ “A1：A” ＆I）=（阵列）将数据插入到新的工作表。
这个答案可能不是你所期待的，但根据您的边注[...]或完全不同的方法]我还是觉得有必要将它张贴...]。
在这里，我有200MB（及以上）的文件时，每个仅仅是文本文件，包括分隔符。我不把它们加载到Excel了。我也有这样的Excel太慢，需要加载整个文件的问题。然而，Excel是在使用Open方法打开这些文件的速度非常快：
Open strFileNameAndPath For Input Access Read Lock Read As #intPointer
在这种情况下，Excel将不加载整个文件，但只是逐行读取它行。因此，Excel可以已处理数据（转发），然后获取数据的下一行。像这样的Excel不啃老族的内存加载200MB。
有了这个方法，我再装填在本地安装SQL将数据直接传送到我们的数据仓库（也SQL）的数据。为了加快使用上述mething和快速获取数据到我在每1000行数据块传输数据的SQL服务器转移。在Excel中的字符串变量最多可容纳2十亿个字符。所以，没有问题存在。
为什么如果我已经使用SQL的本地安装，我不能简单地使用SSIS人们可能不知道。然而，问题是，我不是一个加载所有这些文件了。使用Excel生成允许我这些工具转发给其他人，谁现在上传所有这些文件对于我这个“导入工具”。所有的人都给予访问SSIS不是一种选择，也没有使用注定的网络驱动器，其中一个可以放置这些文件和SSIS会自动加载它们（曾经10+分钟左右）的可能性。
在结束我的代码看起来是这样的。

我认为@Mr。卡罗是正确的，过去从Recordset您的数据到电子表格中是最简单的方法：
Private Sub PopArray()
.....
Set rs = dbConnection.Execute("SELECT * FROM [" & SourceRange & "]")
'' This is faster
Range("A1").CopyFromRecordset rs
''Arr = rs.GetRows
End Sub
但如果你仍然想使用Arrays你可以试试这个：
Sub ArrayTest
'' Array for Test
Dim aSingleArray As Variant
Dim aMultiArray as Variant
'' Set values
aSingleArray = Array("A","B","C","D","E")
aMultiArray = Array(aSingleArray, aSingleArray)
'' You can drop data from the Array using 'Resize'
'' Btw, your Array must be transpose to use this :P
Range("A1").Resize( _
UBound(aMultiArray(0), 1) + 1, _
UBound(aMultiArray, 1) + 1) = Application.Transpose(aMultiArray)
End Sub
