how to delete everything after TAB in text file ?

[Valhalla1]

I've got a text file that consists of 1 line with a few letters/numbers, followed by a TAB, followed by some numbers

is it possible to get autoit to delete the TAB and everything after it, leaving just the characters that preceded the TAB

also once I've got that, how could I have it add line breaks in between every two characters. For example I'd have

2s5cThJs[TAB]5.3322

I'd like it first to chop the tab and trailing numbers, leaving 2s5cThJs

then add the line breaks giving you

2s

5c

#include <File.au3>
Global $aInfile, $hOutfile, $sLeft, $i

If Not _FileReadToArray("test.txt", $aInfile) Then
    ConsoleWrite("!>Unable to read file" & @LF)
    Exit
EndIf

$hOutfile = FileOpen("newtest.txt", 2)
If $hOutfile = -1 Then 
    ConsoleWrite("!>Unable to open output file" & @LF)
    Exit
EndIf

For $i=1 To $aInfile[0]
    $sLeft = StringLeft($aInfile[$i], StringInStr($aInfile[$i], @TAB)-1)
    Do
        FileWriteLine($hOutfile, StringLeft($sLeft, 2))
        $sLeft = StringTrimLeft($sLeft, 2)
    Until StringLen($sLeft) < 2
    If $sLeft <> '' Then FileWriteLine($hOutfile, $sLeft)
Next

FileClose($hOutfile)
