使用PowerShell

Question

我正在尝试使用Powershell通过以下代码将rest API导出到CSV

$DesiredProperties | Export-CSV -Path ".\Testrestapi.csv" -Encoding ASCII -NoTypeInformation

它将以下内容输出到CSV：

,
"105283","TickerID"
"2365512290","TickerID"
,
,
,
,
"US594918AH79","ISIN"
,
,
,
,
"US594918AH79","ISIN"
"2121687888","TickerID"
"US594918AH79","ISIN"
,

所需结果：

"105283","TickerID"
"2365512290","TickerID"
"US594918AH79","ISIN"
"US594918AH79","ISIN"
"2121687888","TickerID"
"US594918AH79","ISIN"

我尝试使用

(gc file.txt) | ? {$_.Trim() -ne ""} | Set-Content file.txt

，但似乎不适用于CSV文件。有人可以告诉我该脚本中应使用哪个命令删除空行“，，，”

Answer 1

您可以使用Where-Object { $_.PSObject.Properties.Value -ne '' }直接清理$DesiredProperties对象。

示例：

  

输入数据：“ C：\ Temp \ Testrestapi.csv”（我在这里使用CSV，但是您应该直接从REST API中获取导出对象：

,
"105283","TickerID"
"2365512290","TickerID"
,
,
,
,
"US594918AH79","ISIN"
,
,
,
,
"US594918AH79","ISIN"
"2121687888","TickerID"
"US594918AH79","ISIN"
,

示例代码：

Import-Csv -Path "C:\Temp\Testrestapi.csv" -Header 'col1','col2' | Where-Object { $_.PSObject.Properties.Value -ne '' } | Export-Csv -Path "C:\Temp\Testrestapi_clean.csv" -NoTypeInformation

  

输出数据：“ C：\ Temp \ Testrestapi_clean.csv”：

"col1","col2"
"105283","TickerID"
"2365512290","TickerID"
"US594918AH79","ISIN"
"US594918AH79","ISIN"
"2121687888","TickerID"
"US594918AH79","ISIN"
