Structure replacement possible complex RegexReplace solution? - regex

Question

I need to run a VBScript that changes the structure of a CSV file. To keep it simple I'm only using 3 data fields but there is a lot more. In a production environment I will have a CSV file with hundreds of lines.
The problem is everything is in double quotes. The end result can sometimes be no quotes or single quotes or sometimes a mix of all three.
I have absolutely no idea how I should approach this and was looking for some guidance. This looks like a job for RegexReplace but because it's mixed I'm not sure how to start this. After the file has been modified I have to right over top of the original file.
CSV Example:
"apple";"12";"xyz"
"somereallylongword";"7687";"theredfox"
Pattern
"%1";%2;'%3'
Desired Result
"apple";12;'xyz'
"somereallylongword";7687;'theredfox'
What I'm trying to achieve is to be able to make a new pattern type.  In my example:
"%1" - I keep the original double quotes.
%2 - Remove the double quotes.
'%3' - Replace the double quotes with single quotes.
Any insight would be greatly appreciated.

You can read the CSV file using ADODB:
Const adOpenStatic = 3
Const adLockOptimistic = 3
Const adCmdText = &H1
Dim objConnection
Dim objRecordset
Dim sCSVFolder
Dim sCSVFile
Dim sValue
Set objConnection = CreateObject("ADODB.Connection")
Set objRecordset = CreateObject("ADODB.Recordset")
sCSVFolder = "C:\CSV_Folder\"
sCSVFile = "your_csv_file.csv"
objConnection.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & sCSVFolder & ";" & _
"Extended Properties=""text;HDR=YES;FMT=Delimited"""
objRecordset.Open "SELECT * FROM " & sCSVFile, _
objConnection, adOpenStatic, adLockOptimistic, adCmdText
Do Until objRecordset.EOF
' Modify and write fields to new text file here
sValue = objRecordset.Fields.Item("FieldName")
objRecordset.MoveNext
Loop
This way you let ADO handle reading the data and removing the double-quotes and you can manipulate the data easily as a Recordset.

Just give a try for this code by replacing the path of your CSV file and tell me how it works on your side ?
Option Explicit
Dim Data
Call ForceCScriptExecution()
Data = ReadFile("C:\Test\Test.csv")
wscript.echo "Before Replacing"
wscript.echo String(50,"-")
wscript.echo Data
wscript.echo String(50,"-")
wscript.echo "After Replacing"
wscript.echo String(50,"-")
wscript.echo Search_Replace(Data)
wscript.echo String(50,"-")
wscript.sleep 20000
'-----------------------------------------------
Function Search_Replace(Data)
Dim oRegExp,strPattern1,strPattern2
Dim strReplace1,strReplace2,strResult1,strResult2
strPattern1 = ";(\x22)(\S+\w+)(\x22);"
strReplace1 = ";$2;"
strPattern2 = "[;]\x22([^\x22]+)\x22"
strReplace2 = ";'$1'"
Set oRegExp = New RegExp
oRegExp.Global = True
oRegExp.IgnoreCase = True
oRegExp.Pattern = strPattern1
strResult1 = oRegExp.Replace(Data,strReplace1)
oRegExp.Pattern = strPattern2
strResult2 = oRegExp.Replace(strResult1,strReplace2)
Search_Replace = strResult2
End Function
'-----------------------------------------------
Function ReadFile(path)
Const ForReading = 1
Dim objFSO,objFile
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile(path,ForReading)
ReadFile = objFile.ReadAll
objFile.Close
End Function
'----------------------------------------------
Sub ForceCScriptExecution()
Dim Arg, Str, cmd, Title
Title = "Search and Replace using RegExp by Hackoo 2019"
cmd = "CMD /C Title " & Title &" & color 0A & Mode 80,30 & "
If Not LCase( Right( WScript.FullName, 12 ) ) = "\cscript.exe" Then
For Each Arg In WScript.Arguments
If InStr( Arg, " " ) Then Arg = """" & Arg & """"
Str = Str & " " & Arg
Next
CreateObject( "WScript.Shell" ).Run _
cmd & "cscript //nologo """ & _
WScript.ScriptFullName & _
""" " & Str
WScript.Quit
End If
End Sub
'-----------------------------------------------
Edit : Batch Script Code
You can do it easily with a batch script without using Regex :
#echo off
Title Edit CSV File
Set "Input_CSV_File=C:\Test\Test.csv"
Set "OutPut_CSV_File=C:\Test\OutPut_Test.csv"
If Exist "%OutPut_CSV_File%" Del "%OutPut_CSV_File%"
#for /f "tokens=1,2,3 delims=;" %%a in ('Type "%Input_CSV_File%"') Do (
echo "%%~a";%%~b;'%%~c'
echo "%%~a";%%~b;'%%~c'>>"%OutPut_CSV_File%"
)
TimeOut /T 5 /NoBreak>nul
If Exist "%OutPut_CSV_File%" Notepad "%OutPut_CSV_File%" & Exit
