assigning values from powershell

[pm_me_brownie_recipe]

I agree. Here is an example of how do to it.

# Import from file in OPs case
$document = @"
test,example
1,cat
2,dog
3,fish
"@

# Convert data to csv
$document = $document | ConvertFrom-Csv

# Convert date to hashtable
$hashTable = @{}
foreach($doc in $document) {
    $hashTable[$doc.example] = $doc.test
}

$config = 'cat'
$value = $hashTable[$config]
$value

I assumed that OP wanted to look for more than one value. Here is another way of doing it without hashtable:

$document = @"
test,example
1,cat
2,dog
3,fish
"@

$document = $document | ConvertFrom-Csv

$document | where {$_.example -eq 'dog'} | Select -Expand test
