Question

我正在根据BusinessUnit（它是csv文件中的一列）将csv文件拆分为较小的csv文件。

直到现在我都尝试过：-

$fullpath = "C:\Batch\Output Folder\ErroreportforAllregions.csv"

$path = Split-Path $fullpath -parent
$data = Import-CSV  -Path $fullpath -Header BusinessUnit,Date,Time,PolicyNum


foreach ($group in $data | Group BusinessUnit){        
    $data | Where-Object {$_.species -eq $group.name} | 
        ConvertTo-Csv -NoTypeInformation | 
         foreach {$_.Replace('"','')}|
        Out-File "$path\$($group.name).csv"     
}

但是在这种情况下，行（数据）不在小型csv文件中。请指导我哪里出错了。

我在大型csv文件中的数据：-

BusinessUnit    serialno
Eastern Region   1
Ottawa           2
India            3

输出应为

EasternRegion.csv
Ottawa.csv
India.csv

Answer 1

假设您的大型csv实际上是这样的：

"BusinessUnit","Date","Time","PolicyNum","serialno"
"Eastern Region","2019-02-04","11:09:45","123","1"
"Eastern Region","2019-02-03","10:09:45","123","1"
"Ottawa","2019-02-04","11:09:45","123","1"
"India","2019-02-04","11:09:45","123","1"

然后应该这样做：

$fullpath = "C:\Batch\Output Folder\ErroreportforAllregions.csv"
$path = Split-Path $fullpath -parent
$data = Import-CSV -Path $fullpath

$data | Group-Object -Property BusinessUnit | ForEach-Object {
    $file = Join-Path -Path $path -ChildPath ($_.Name + '.csv')
    $_.Group | Export-Csv -Path $file -NoTypeInformation
}

使用上方的数据，它将创建三个名为Eastern Region.csv，Ottawa.csv和India.csv的csv文件。

东部地区.csv

"BusinessUnit","Date","Time","PolicyNum","serialno"
"Eastern Region","2019-02-04","11:09:45","123","1"
"Eastern Region","2019-02-03","10:09:45","123","1"

Ottawa.csv

"BusinessUnit","Date","Time","PolicyNum","serialno"
"Ottawa","2019-02-04","11:09:45","123","1"

India.csv

"BusinessUnit","Date","Time","PolicyNum","serialno"
"India","2019-02-04","11:09:45","123","1"

希望这会有所帮助
