导入不带格式的 CSV

Question

我正在尝试将 CSV 文件导入我当前的工作簿；但是，它会自动格式化我的一些数据。有没有办法防止这种情况发生？

---

示例：

01JAN-1

自动转换为：

01 年 1 月 1 日

---

我查找了添加Local:= true，但我不确定如何实现它。我试过wb = Workbooks.Open(fileImportName, Local:=True)

---

代码：

Sub file_Import()

    Application.ScreenUpdating = False
    Application.DisplayAlerts = False

    Dim fileImportPath As String, fileImportName As String, total As Integer, currentWorkbook As String

    fileImportPath = "C:\Users\UserName\Desktop\Test Data.csv"
    fileImportName = "Test Data.csv"
    currentWorkbook = "Testing Import.xlsm"
    total = Workbooks(currentWorkbook).Worksheets.Count

    Workbooks.Open (fileImportName)

    Workbooks(fileImportName).Worksheets(Sheets(1).Name).Copy _
    After:=Workbooks(currentWorkbook).Worksheets(total)

    Workbooks(fileImportName).Close

    Application.ScreenUpdating = True
    Application.DisplayAlerts = True

End Sub

下面的代码尝试覆盖第一个工作表的内容。为了安全起见，在运行之前保存工作簿的副本。您需要提供 CSV 的完整路径。我假设您在 CSV 的每一行上都有相同数量的列：

Option explicit

Sub CSVtoSheet()

Const FILEPATH as string = "C:\New Folder\test.csv" 'Replace with your own path; or consider changing to variable and assign dynamically.'

Const DELIMITER as string = ","

' Read into memory; assumes file will fit and is not too big.'
Dim FileContents as string
Open FILEPATH for binary access read as #1
Filecontents = space$(lof(1))
Get #1, 1, filecontents
Close #1

' Assign lines in file to 1-dimensional, 0-based array of strings'
Dim AllLines() as string
AllLines = split(filecontents,vbNewLine)

Dim NumberOfRows as long
Dim NumberOfColumns as long

NumberOfRows = ubound(alllines)+1'Watch out if last line of CSV is blank, as is sometimes the case. Rows which do not contain column delimiter can produce error/unwanted behaviour.'

' Assume number or columns is fixed throughout CSV and can be reliably deduced from first line alone'
NumberOfColumns = ubound(split(alllines(lbound(alllines)),delimiter))+1

Dim ArrayToWriteToSheet() as string 'Change to as variant if you need numeric values as numbers'
Redim ArrayToWriteToSheet(1 to NumberOfRows, 1 to NumberOfColumns)

' Iterate through each element in array'
Dim RowIndex as long, ColumnIndex as long
Dim TemporaryArray() as string

For RowIndex = lbound(arraytowritetosheet,1) to ubound(arraytowritetosheet,1)

If Len(alllines(rowindex-1)) > 0 then ' Skip any blank lines; sometimes final line in CSV is empty which can result in errors/unwanted behaviour.'

TemporaryArray = split(alllines(rowindex-1),delimiter)

For ColumnIndex = lbound(arraytowritetosheet,2) to ubound(arraytowritetosheet,2)

Arraytowritetosheet(RowIndex,ColumnIndex) = temporaryarray(columnindex-1)

Next columnindex

End if

Next rowindex

'Write to first sheet in workbook. Hopefully, Excel will not do any unwanted auto-conversion.'
Thisworkbook.worksheets(1).range("A1"). Resize(ubound(arraytowritetosheet,1),ubound(arraytowritetosheet,2)).value2 = arraytowritetosheet

End sub

它做你想做的事吗？从理论上讲，一旦您在内存中获得了值，您就可以在写回工作表之前随意格式化/呈现。
