[英]Losing data through csv file opening loop vba
我每天晚上 8 點后從 5 個合作伙伴那里獲得 CSV 數據集。 文件在同一文件夾中的結構相同,大小范圍為 4-130 KB。 我想通過宏將所有文件合並為一個,今天的結果是缺少 10-15 天。 16日(最后一天)的數據不錯。 當我只為一個合作伙伴運行宏時,我得到了完整的結果。 可能是什么問題?
Dim MyFolder As String
Dim MyFile As String
Dim last As Integer
Dim newrow As Integer
Dim sh As Worksheet
Dim name As String
Dim name2 As String
Dim myYear As Variant
Dim myMonth As Variant
Sheets("Munka1").Select
name = ActiveWorkbook.name
ScreenUpdating = False
Range(Cells(2, 1), Cells(300000, 200)).Select
Selection.Clear
Cells(2, 1).Select
MyFolder = "InputFolder"
MyFile = Dir(MyFolder & "\FILE_*" & "*.csv")
Do While MyFile <> ""
Workbooks.Open Filename:=MyFolder & "\" & MyFile, Local:=True
name2 = ActiveWorkbook.name
On Error Resume Next
Range(Cells(2, 1), Cells(3000, 11)).Select
Selection.Copy
Windows(name).Activate
Cells(newrow, 1).Select
ActiveSheet.Paste
last= Range("A1", Range("A1").End(xlDown)).Rows.Count
newrow = last + 1
Application.CutCopyMode = False
Windows(name2).Close savechanges:=False
MyFile = Dir
Loop
你能像這樣嘗試並反饋嗎?

我只需要將 last 和 newraw 變量更改為 long。
