Powershell 导出Csv添加不需要的标题双引号
我得到了一个源CSV文件（没有标题，所有列都用逗号分隔），我正在尝试根据第一列中的值将其拆分为单独的CSV文件，并使用该列值作为输出文件名 输入文件： S00000009,2016,M04 01/07/2016,0.00,0.00,0.00,0.00,0.00,0.00,750.00,0.00,0.00 S00000009,2016,M05 01/08/2016,0.00,0.00,0.00,0.00,0.00,0.00,600.00,0.00,0.00 S00000009,2016,M06 01/09/2016,0.00,0.00,0.00,0.00,0.00,0.00,600.00,0.00,0.00 S00000010,2015,W28 05/10/2015,2275.00,0.00,0.00,0.00,0.00,0.00,0.00,0.00,0.00 S00000010,2015,W41 04/01/2016,0.00,0.00,0.00,0.00,0.00,0.00,568.75,0.00,0.00 S00000010,2015,W42 11/01/2016,0.00,0.00,0.00,0.00,0.00,0.00,568.75,0.00,0.00 S00000012,2015,W10 01/06/2015,0.00,0.00,0.00,0.00,0.00,0.00,650.00,0.00,0.00 S00000012,2015,W11 08/06/2015,0.00,0.00,0.00,0.00,0.00,0.00,650.00,0.00,0.00 S00000012,2015,W12 15/06/2015,0.00,0.00,0.00,0.00,0.00,0.00,650.00,0.00,0.00 输出文件：Powershell 导出Csv添加不需要的标题双引号,powershell,csv,header,export-csv,Powershell,Csv,Header,Export Csv,我得到了一个源CSV文件（没有标题，所有列都用逗号分隔），我正在尝试根据第一列中的值将其拆分为单独的CSV文件，并使用该列值作为输出文件名 输入文件： S00000009,2016,M04 01/07/2016,0.00,0.00,0.00,0.00,0.00,0.00,750.00,0.00,0.00 S00000009,2016,M05 01/08/2016,0.00,0.00,0.00,0.00,0.00,0.00,600.00,0.00,0.00 S00000009,2016,M06 0
s0000009.csv首先，.csv文件需要标题和引号作为csv文件结构。但如果你不想要它们，你可以继续使用文本文件或
$temp = Import-Csv INPUT_FILE.csv -Header service_id,year,period,cash_exp,cash_inc,cash_def,act_exp,act_inc,act_def,comm_exp,comm_inc,comm_def | Group-Object -Property "service_id" |
Foreach-Object {
$path=$_.name+".csv"
$temp0 = $_.group | ConvertTo-Csv -NoTypeInformation | Select-Object -Skip 1
$temp1 = $temp0.replace("""","")
$temp1 > $path
}
希望这能有所帮助。对于您的特定场景，您可能可以使用更简单的方法。以纯文本文件的形式读取输入文件，通过拆分第一个字段将行分组，然后将组写入以组命名的输出文件：
Get-Content 'INPUT_FILE.csv' |
Group-Object { $_.Split(',')[0] } |
ForEach-Object { $_.Group | Set-Content ($_.Name + '.csv') }
- 只使用数字而不使用命名标题（因为输出中不需要数字）
- 避免不必要的临时文件
- 仅删除分隔双引号的字段
对于Q1，请看这里：，对于Q2，请看这里：谢谢Stef，它工作得非常好，输出文件的格式很好。可以强制将新创建的.csv文件输出到其他文件夹吗？默认为当前文件夹。我尝试在$path=$\uu.name+.csv行上指定一个子文件夹。我尝试了类似于$out\u file=\output\$\uu.name+.csv的方法。我已经解决了上一个问题（我已经将outpath定义为子文件夹）$path=$out\u path+'\'+$\uu.name+.csv
Get-Content 'INPUT_FILE.csv' |
Group-Object { $_.Split(',')[0] } |
ForEach-Object { $_.Group | Set-Content ($_.Name + '.csv') }
Import-Csv INPUT_FILE.csv -Header (1..12) |
Group-Object -Property "1" | Foreach-Object {
($_.Group | ConvertTo-Csv -NoType | Select-Object -Skip 1).Trim('"') -replace '","',',' |
Set-Content -Path ("{0}.csv" -f $_.Name)
