如何将值从哈希表转换为其他列？

Question

I'm new in Power Shell so I'm having a hard time to understand which command to use to a certain operation.

PROBLEM: I have a hash table where every parameter can have 4 different words in a string that composes the field VALUE. Eg.:

$table:

Name                    Value
-----                   --------
parameter 1             F15 STK15                                                                                                                                                             
parameter 2             STK15
parameter 3             GP F15 STK15

As you can see, the table has 3 parameters and each parameter value is a STRING that could be formed by 3 different words: STK F15 and GP.

What I really need is to EXPORT this hash table to EXCEL in 4 different columns:

NAME    GP   STK15    F15

So in EXCEL there will be 4 columns:

NAME          GP    STK15    F15
parameter1    NULL  STK15    F15
and so on.

I don't know how to do it, piping with | out-GridView or what ever.

If I could divide the string into 3 columns it already would be perfect. can someone help me ?

Answer 1

You can do the following:

$table = @{parameter1="F15 STK15";parameter2="STK15";parameter3="GP F15 STK15"}
$outArray = @()

foreach($entry in $table.GetEnumerator()) {
   $o = new-object PSCustomObject
   $o | Add-Member -notepropertyName "NAME" -notepropertyvalue $entry.name
   "F15","STK15","GP" | % { 
      if($entry.Value -match $_) {
        $o | Add-Member -notepropertyname "$_" -notepropertyvalue "$_"
      }
      else {
        $o | Add-Member -notepropertyname "$_" -notepropertyvalue "NULL"
      }
    }  
    $outArray += ,$o
}   

Iterate over the table and check for a match of each of the data you're trying to identify. Create a custom object for each value in the hashtable and populate it with the name, the required data and whether or not the each of the data were matched. Then append the object to an array.

You then have an object as such:

[PS] > $outArray | ft -auto

NAME       F15  STK15 GP
----       ---  ----- --
parameter2 NULL STK15 NULL
parameter1 F15  STK15 NULL
parameter3 F15  STK15 GP

And you can convert it to a csv format for exporting to Excel;

[PS] > $outArray | sort -Property NAME | ConvertTo-Csv -NoTypeInformation
"NAME","F15","STK15","GP"
"parameter1","F15","STK15","NULL"
"parameter2","NULL","STK15","NULL"
"parameter3","F15","STK15","GP"
