Question

версии CSV У меня есть два CSV-файлы, как например:

1) Records.csv

Account,TransactionDate,Description,Amount 
Acct1,1/1/2015,Shopping at Kohls,($35.00) 
Acct1,1/1/2016,Shopping at Target,($25.22) 
Acct1,1/1/2016,Shopping at Target,($60.00) 
Acct2,4/5/2015,Subway,($9.12) 
Acct2,1/1/2016,Jimmy Johns,($11.00) 
Acct3,1/1/2016,Shopping at Kohls,($35.00) 
Acct1,1/1/2016,Shopping at Kohls,$35.00 
Acct1,1/1/2016,Shopping at Target,($60.00) 
Acct2,4/5/2015,Subway,($9.12) 
Acct2,1/1/2016,Jimmy Johns,($11.00) 
Acct2,1/1/2016,Jimmy Johns,($11.00) 
Acct3,1/1/2016,Shopping at Kohls,($35.00) 
Acct3,1/1/2016,Kroger,($27.00) 

и 2) rules.csv:

Description,Category,Topic 
Shopping at Kohls,Misc,Clothing 
Subway,Food,Restaurants 
Jimmy Johns,Food,Restaurants 
Shopping at Target,Misc,Home 
Kroger,Food,Groceries 

мне нужно добавить категорию и тему из rules.csv в файл records.csv, на основе соответствующего описания.

Когда я запускаю следующий код, он работает, но добавляет всю строку в rules.csv в одно поле. Мне нужно добавить его в отдельные столбцы.

$rules = import-csv "rules.CSV" 
import-csv "Records.csv" | % { 
    $desc=$_.Description 
    $_ | Add-Member NoteProperty "Category" ($rules | select-string -SimpleMatch $desc) -PassThru 
} | export-csv "output.csv" -notype 

Результат выглядит так, но мне нужно разделить последний столбец.

"Account","TransactionDate","Description","Amount","Category" 
"Acct1","1/1/2015","Shopping at Kohls","($35.00)","@{Description=Shopping at Kohls; Category=Misc; Topic=Clothing}" 
"Acct1","1/1/2016","Shopping at Target","($25.22)","@{Description=Shopping at Target; Category=Misc; Topic=Home}" 
"Acct1","1/1/2016","Shopping at Target","($60.00)","@{Description=Shopping at Target; Category=Misc; Topic=Home}" 
"Acct2","4/5/2015","Subway","($9.12)","@{Description=Subway; Category=Food; Topic=Restaurants}" 
"Acct2","1/1/2016","Jimmy Johns","($11.00)","@{Description=Jimmy Johns; Category=Food; Topic=Restaurants}" 
"Acct3","1/1/2016","Shopping at Kohls","($35.00)","@{Description=Shopping at Kohls; Category=Misc; Topic=Clothing}" 
"Acct1","1/1/2016","Shopping at Kohls","$35.00 ","@{Description=Shopping at Kohls; Category=Misc; Topic=Clothing}" 
"Acct1","1/1/2016","Shopping at Target","($60.00)","@{Description=Shopping at Target; Category=Misc; Topic=Home}" 
"Acct2","4/5/2015","Subway","($9.12)","@{Description=Subway; Category=Food; Topic=Restaurants}" 
"Acct2","1/1/2016","Jimmy Johns","($11.00)","@{Description=Jimmy Johns; Category=Food; Topic=Restaurants}" 
"Acct2","1/1/2016","Jimmy Johns","($11.00)","@{Description=Jimmy Johns; Category=Food; Topic=Restaurants}" 
"Acct3","1/1/2016","Shopping at Kohls","($35.00)","@{Description=Shopping at Kohls; Category=Misc; Topic=Clothing}" 
"Acct3","1/1/2016","Kroger","($27.00)","@{Description=Kroger; Category=Food; Topic=Groceries}" 

Любой способ сделать это?

* редактировать: если вы не хотите использовать другой сценарий, это также должно работать

foreach ($record in $a) { 
    foreach ($obj in $b) { 
     if ($obj.description -eq $record.description) { 
      $record | select *, @{n='Category';e={$obj.Category}}, @{n='Topic';e={$obj.Topic}} 
     } 
    } 
}
