您有第一行关键字:
"B,C,D,E"
但您希望在开头插入"A"
,例如
"A,B,C,D,E"
您可以阅读整行,并在逗号(,)上拆分。然后在循环中重建字符串,并在索引的特殊情况下使用新关键字。
Dim keywords As String
Dim newKeywords As String
Dim arr() As String
Dim keywordToInsert As String
Dim i As Integer
keywords = "B,C,D,E"
keywordToInsert = "A"
arr = Split(keywords, ",")
For i = 0 To UBound(arr) Step 1
If i = 0 Then
newKeywords = keywordToInsert
End If
newKeywords = newKeywords & "," & arr(i)
Next i
这会为您提供关键字。使用这个循环,你应该能够提出自己的循环来读取每一行,并像这样操作第一列。

这假设您知道CSV文件中的列:
Private Sub RewriteFile(ByRef the_sFileName As String)
Dim sFileNameTemp As String
Dim iFileNoInput As Integer
Dim iFileNoOutput As Integer
Dim iField1 As Integer
Dim sField2 As String
Dim datField3 As Date
' Temporary file name.
sFileNameTemp = the_sFileName & ".tmp"
iFileNoInput = FreeFile
Open the_sFileName For Input As #iFileNoInput
iFileNoOutput = FreeFile
Open sFileNameTemp For Output As #iFileNoOutput
Do Until EOF(iFileNoInput)
' Read in each field of each line into a separate variable, then write to temporary file together with new field. (If you don't know a field's type, use Variants)
Input #iFileNoInput, iField1, sField2, datField3
Write #iFileNoOutput, Elaborate(iField1, sField2), iField1, sField2, datField3
Loop
Close #iFileNoOutput
Close #iFileNoInput
' Delete the original file, and replace with new file.
Kill the_sFileName
Name sFileNameTemp As the_sFileName
End Sub

或者我可以将原始csv文件上传到数据表中,在表单中的数据网格中将其可视化,然后直接向数据表添加一列
