Process TXT like excel column

[LWC]

I've updated the "add a column" feature to be able to actually add a column and not replace it:

; add column with values
$insert_column = 3 ; which column to enter
ReDim $aData[$aData[0][0]+1][ubound($aData, 2)+1]
For $i=1 To $aData[0][0]
    For $j=ubound($aData, 2)-1 to $insert_column Step -1
        $aData[$i][$j]=$aData[$i][$j-1]
    next
    $aData[$i][$insert_column-1]= 'Foobar'
Next
_ArrayDisplay($aData)   ; display the result

@Terenz, i really hope that by now you started coding it by yourself, rather than waiting for my reply. if you did, you probably already have it working, and you won't be needing this:

#include <Array.au3>
#include "_filearray2d.au3"

; declare variables
Dim $aData[1]
Global $sFile=@ScriptDir&'\data.txt'

_FileToArray2D($sFile,$aData,' - ') ; get initial data
_ArrayDisplay($aData)   ; display it for verification

; add index
For $i=1 To $aData[0][0]
    $aData[$i][0]&=$i
    $aData[$i][1]&=$i
Next
_ArrayDisplay($aData)   ; display the result

; add column with values
ReDim $aData[$aData[0][0]+1][3]
For $i=1 To $aData[0][0]
    $aData[$i][2]=$aData[$i][1]&' in 3rd column'
Next
_ArrayDisplay($aData)   ; display the result

; remove columns except 1st
ReDim $aData[$aData[0][0]+1][1]
_ArrayDisplay($aData)   ; display the result

this is based on the functions i mentioned earlier, but slightly modified. save this code by the name "_filearray2d.au3" in the same folder as the script above:

save your data in the text file "data.txt" in the same folder as the script, then launch the script. enjoy!
