Convert a string into 2D Array

Good evening :)
I was looking around the forum if I could find a function that allows to convert a string into a 2 dimensional array...
The first column of the array is always the same, but the rows could change...
I have a pattern like:

Column A|Column B
Static Text 1|Data 1
Static Text 2|Data 2
Static Text 3|Data 3
Static Text 4|Data 4

Where, Static Text (1...4) will be always the same, and I don't want to change them... But, Data 1...4 are dynamic fields... So, I could have the pattern above AND I coould have the pattern I'm going to show you right below :)

Column A|Column B
Static Text 1|Data 1
Static Text 2|Data 2
Static Text 3|Data 3
Static Text 4|Data 4
Static Text 1|Data 5
Static Text 2|Data 6
Static Text 3|Data 7
Static Text 4|Data 8

How can I do in this case?

Thanks for everyone's help :)

That should be easy enough to accomplish.  One question I have is: where, and in what format, does the data come in (text file, string at a time, etc.)?  The clearer the requirements, the less re-work will be needed to shape the code to fit the data input.

Hi @spudw2k:)
Thanks for asking.
The string comes from a For...In Loop, and it's in the string format...
So I do something like this:
  

For $oElement In $oQuery
    $sStringToArray &= $oElement.SomeData1 & _
                       $oElement.SomeData2 & _
                       $oElement.SomeDataN
Next

And the, I use StringSplit() to obtain the array...

Thanks for your help! :)

Ok, so is the following produced after StringSplit?

Column A|Column B
Static Text 1|Data 1
Static Text 2|Data 2
Static Text 3|Data 3
Static Text 4|Data 4
So this ^ is already a single dimension array?

 

I am curious, what does the string look like before you perform the StringSplit, particularly what delimiter are you using?  Just trying to get a clear picture.

Here is one fairly simple solution. 

#include <MsgBoxConstants.au3>  ;$STR_NOCOUNT Const
#include <Array.au3>            ;_Array* Functions

Local $aArray[]=["Column A|Column B","Static Text 1|Data 1","Static Text 2|Data 2","Static Text 3|Data 3","Static Text 4|Data 4"]   ;Demo array to mimic dataset
_ArrayDisplay($aArray, "Starting Dataset")      ;Dataset look correct?

Local $a2DArr = StringSplit($aArray[0],"|",$STR_NOCOUNT)    ;Create new Array with first row of dataset above (Header)
_ArrayTranspose($a2DArr)    ;Convert to 2D array

For $iX = 1 To UBound($aArray)-1        ;Fill 2D Array
    _ArrayAdd($a2DArr,$aArray[$iX])
Next

_ArrayDisplay($a2DArr, "Populated 2D array")        ;Display filled 2D array

Just out of curiosity, why not move the logic up a level and use _ArrayAdd, like so: 

;instead of
For $oElement In $oQuery
    $sStringToArray &= $oElement.SomeData1 & _
                       $oElement.SomeData2 & _
                       $oElement.SomeDataN
Next
...
StringSplit...
etc...

;Define your array ahead of time, then populate it through your For Loop
For $oElement In $oQuery
    _ArrayAdd($myArray, $oElement.SomeData1 & "|" & $oElement.SomeData2 & "|" & $oElement.SomeDataN
Next

Agreed, the sooner (less work) the dataset can be formatted the better.

can you show a couple of legit values? 

What are you splitting on?  There is no pipe or CR added during the loop you provided just somedataX smashed together for ubound number of times. 

,-. .--. ________ .-. .-. ,---. ,-. .-. .-. .-.
|(| / /\ \ |\ /| |__ __||| | | || .-' | |/ / \ \_/ )/
(_) / /__\ \ |(\ / | )| | | `-' | | `-. | | / __ \ (_)
| | | __ | (_)\/ | (_) | | .-. | | .-' | | \ |__| ) (
| | | | |)| | \ / | | | | | |)| | `--. | |) \ | |
`-' |_| (_) | |\/| | `-' /( (_)/( __.' |((_)-' /(_|
'-' '-' (__) (__) (_) (__)

@Luigi My first shot was like yours, but I opted to avoid using _ArrayDelete for the first (empty) row.  Doing some quick perf comparrisons, it doesn't seem to have major impact.  Good stuff.

#include <array.au3>

local $aArray[0][2]

local $oQuery = ["Static Text 1" , "Data 1" , "Static Text 2" , "Data 2" , "Static Text 3" , "Data 3" ,"Static Text 4" , "Data 4"]

$flag = ""
$i = 0

For $oElement In $oQuery
    If $flag = 0 Then
        _ArrayAdd($aArray , $oQuery[$i]  , 0)
        $flag = 1
        $i+=1
        Else
        $aArray[ubound($aArray) - 1][1]=$oQuery[$i]
        $flag = 0
        $i+=1
    EndIf
Next

_ArrayDisplay($aArray)

 

I ask because it seems you could do it in the loop, if the return is any kind of reliable format.  I don't have a nice object example but the above array example should accurately reflect the thought

@iamtheky I didn't know you could declare an array like that ($aArray[0][2]), pretty cool.

@Luigi That ^ would eliminate the need for the _ArrayDelete

you need the additional conditions if using a For..In Loop, or you will blow the bounds

Good evening @JLogan3o13!
In this case, how can I have a 2D array? Should I do something like this? :)

For $oElement In $oQuery
    _ArrayAdd($myArray, $sHeaderRow1 & "|" & $oElement.SomeData1 & @CRLF & _
                        $sHeaderRow2 & "|" & $oElement.SomeData2 & @CRLF & _
                        $sHeaderRowN & "|" & $oElement.SomeDataN
Next


Thank you :)

Why are you putting a carriage return in your elements? Have you tried it yourself, to determine if it comes out as you would expect?
