我有一个莲花123文件导出到excel文件。从lotus转换为excel没有问题。我现在面临的唯一问题是如何将它从excel转换为MS Access数据库。
记录由多行而不是一行组成。将记录与记录分开的唯一标志是等号。
以下是excel文件中的示例记录:
我想创建一个Visual Basic程序来自动转换,但我不知道从哪里开始。我也知道PHP但是想知道怎么做。
以下是示例文件:

在将数据转换为Lotus工作簿之前,数据看起来像是在某个系统中准备的。尝试找到源系统,以查看数据是否采用更易于解析的格式。
如果没有,你可能需要创建一个自定义解析器来读取行,直到你到达'='分隔符,然后连接文本块,修剪空格,以使列正确对齐。
您可以尝试以制表符分隔格式保存工作簿并运行以下
' ParseSheet.vbs
Dim fso, Text, Out
Set fso = CreateObject("Scripting.FileSystemObject")
Set Text = fso.OpenTextFile("sample.txt")
Set Out = WScript.StdOut
Dim Columns
Dim Delimiter
Dim Content()
Dim Tab
Dim Line
Tab = Chr(9)
Sub ParseLine(Line)
Dim Column
Dim Delimiter
Dim Value
Column = 1
Line = Line & ":" ' Ensure each row is terminated by the delimiter
Do While Instr(Line, ":") > 0
Value = Left(Line, Instr(Line, ":") - 1)
Value = Replace(Value, Tab, "")
' Skip over column separators
Column = Column + 1
If Column > Columns Then
Columns = Column
ReDim Preserve Content(Columns) ' Grow array to match data
Content(Columns) = ""
End If
If Left(Value, 1) = """" Then ' Strip Quoted strings
Value = Mid(Value, 2, Len(Value) - 2)
End If
If Len(Value) > 0 Then ' Introduce space between most non-empty segments
If (Len(Content(Column)) = 0) Or (Right(Content(Column), 1) = "/") Then
Delimiter = ""
Else
Delimiter = " "
End If
Content(Column) = Content(Column) & Delimiter & Value
End If
Line = Mid(Line, Instr(Line, ":") + 1, Len(Line) - Instr(Line, ":"))
Loop
End Sub
Function Strip(Line)
' Canonicalise emphasised text
Line = Replace(Line, " ", "~")
Line = Replace(Line, " ", "")
Line = Replace(Line, "~", " ")
Strip = Line
End Function
Sub WriteContent(Columns)
Delimiter = ""
For Column = 1 To Columns
Out.Write Delimiter & Trim(Content(Column))
Delimiter = Tab
Content(Column) = ""
Next
Out.WriteLine
End Sub
ReDim Content(1)
Columns = 1
Content(1) = "Group"
Line = Text.ReadLine
Do While Not Text.AtEndOfStream
If Left(Line, 1) = "=" Then
Line = Text.ReadLine
Do While Left(Line, 1) <> "="
Call ParseLine(Line)
' Strip expanded columns
For Column = 2 To 3
Content(Column) = Strip(Content(Column))
Next
Line = Text.ReadLine
Loop
Call WriteContent(Columns)
Line = Text.ReadLine
' Read Group as special case
Content (1) = Strip(Left(Line, Instr(Line, Tab) - 1))
Line = Text.ReadLine
Else
Line = Text.ReadLine
Do While Left(Line, 1) <> "-"
Call ParseLine(Line)
Line = Text.ReadLine
Loop
Call WriteContent(Columns)
End If
Loop
使用CScript ParseSheet.vbs //NoLogo sample.txt > sample.tab
大致查看所需内容。
结果是制表符分隔的控制台输出,它使用行分隔符将多行列展开为单行,并顺便删除扩展标题中的无偿空格。
这不是一个代码风格的好例子,而是一个可以完成一次性转换的工作。
