Wired Text File Format

Hi,

I have a text file contains data extracted from security logs from from different servers. The format of the data looks like this

Header row

Computer,LogFile,Type,Source,EventID,EventCode,User,Date,Time,Category,CategoryString,EventType,Description


Detail row

ServerName,Security,Audit Success,Security,540,540,DomainUserName,20061231,13:36,2,Logon/Logoff,4,Successful Network Logon:

 User Name: UserName

 Domain:  Domain

 Logon ID:  (0x0,0xD4118FE)

 Logon Type: 3

 Logon Process: Kerberos

 Authentication Package: Kerberos

 Workstation Name: 

 Logon GUID: {4bcdc9b4-4caa-ce31-b202-459f1865a477}

 Caller User Name: -

 Caller Domain: -

 Caller Logon ID: -

 Caller Process ID: -

 Transited Services: -

 Source Network Address: XX.XX.XXX.XX

 Source Port: 0

If I tries to extract data as Delimited the columns are not containing the same data for each row as there are some wired characters in the "Description" filed.

How can I extract this data as proper csv file? If not is there a way to extract only ther first line in detail row as shown below

Success,Security,540,540,DomainUserName,20061231,13:36,2,Logon/Logoff,4,Successful Network Logon:

If I tries to extract as Fixed Width, it still not work. Kindly suggest, How I can achive this.
