Convert DAT files to HTML files

Any suggestions how I can convert DAT files to HTML files other than online available tools as they are not working for my files? Thanks

What program created the DAT files?
I assume you mean files with a .dat file extension which is a pretty nondescript extension - could be any format...

What DAT files? How would you like them to look in HTML? What on line tools don't work?

We can't help without some details.

It is a big dataset with .dat extension files containing html tags. In each file we have set of documents which I want to extract each as a separate html file. I have no idea what program created the files.

Assuming each document starts with a unique HTML tag and ends with one as well this would be very easy to do. All you have to do is parse the file looking for the start tag, write the data out to a new file until you reach the end tag, rinse and repeat.

I've done this in QuickBASIC 4.5, PDS 7.0, Visual BASIC and once even using the BASIC Stamp 2 with a Memory Stick Datalogger to exract GPS information from a KML file.

I've also done this to update/upgrade one file set to match another (formatting).

You could also do this with a .vbs (visual basic script) utilizing the FileSystemObject TextStream object. The script can be created with Notepad. Just double click the .vbs file to execute the script...

Here is a little script to get you started - it lists cookie exceptions from Chrome settings:

option explicit
  Const TemporaryFolder = 2
  Const ForWriting = 2
  Const ForReading = 1
  Const TristateFalse = 0
  Const TristateTrue = -1
  Const TristateUseDefault = -2
  Const pattrn = """pattern_pairs"":{"
'  Const pattrn2 = """automatic_downloads"":{"
  Const pattrn2 = """automatic_downloads"":{},""cookies"":{"


  dim WSHShell, fso, ts, UserProfile, PrefsFldr, ChromePrefs

  PrefsFldr = fso.BuildPath(UserProfile, "AppData\Local\Google\Chrome\User Data\Default\Preferences")

' "C:\Users\Ron Czapala\AppData\Local\Google\Chrome\User Data\Default\Preferences"

  If fso.FileExists(PrefsFldr) Then
    GetPrefs
  else
    msgbox PrefsFldr,vbcritical, "Not found"
   end if

Public Sub GetPrefs()
  dim idx, idy, msg, xcepts, i, mydocs, xfile, xts

  HTML1 xts

  xts.writeline PrefsFldr & "<BR><HR>"
  idx = InStr(1,ChromePrefs,  pattrn2, vbTextCompare)
  if idx > 0 then
    ChromePrefs = Mid(ChromePrefs, idx + len(pattrn2)+1)
    idx = InStr(1, ChromePrefs, "}}", vbTextCompare)
    If idx > 0 Then
      ChromePrefs = Mid(ChromePrefs, 1, idx + 1)
    End If
'    msgbox ChromePrefs

    xcepts = Split(ChromePrefs, "},""")

          xts.writeline Process_Entry(xcepts(i)) & "<BR>"
        End If
      End If
    Next
  Else
    Msgbox pattrn & " not found",vbCritical,"Error" 
  End If

  xts.close
  shell.Open xfile

Private Sub HTML1(xts)
