将 excel 转换为 csv 时空单元格引号不会出现

Question

我正在尝试使用此命令通过 power shell 将 excel 文件导入为 csv 格式

import-excel c:\users\xxxx\TestFile.xlsx | export-csv c:\users\xxx\CSVFile.csv -NoTypeInformation  -Encoding UTF8

它工作正常，但问题是当列值为空时，双引号不会出现。

样品输出：-

"98456","Millan, Don K","Millan","Don","K",,"MD","SPECIALISTS","UROLOGY",,,,"0-99",,

所需输出：-

"98456","Millan, Don K","Millan","Don","K","","MD","SPECIALISTS","UROLOGY","","","","0-99","",""

我的excel输入数据如下

那么在powershell中转换为csv时有什么方法可以获取所有空单元格的引号。

Answer 1

您的“缺失”值意味着属性是

$null

:

PS> [pscustomobject] @{
    "col1"  = "val1"
    "col2" = $null
    #        ^^^^^ null value
    "col3" = "val3"
} | convertto-csv

"col1","col2","col3"
"val1",,"val3"
#     ^^ no content

如果您想在输出中使用空的带引号的字符串，则需要将该值放入数据中：

PS> [pscustomobject] @{
    "col1" = "val1"
    "col2" = ""
    #        ^^ empty string
    "col3" = "val3"
} | convertto-csv

"col1","col2","col3"
"val1","","val3"
#      ^^ empty string

因此，在使用

import-excel

导入数据后，迭代所有结果并将任何

$null

值更改为

""

，然后再调用 export-csv：

$data = import-excel c:\users\xxxx\TestFile.xlsx

foreach( $item in $data }
{
   foreach( $property in $item.psobject.properties )
   {
       if( $null -eq $property.Value ) { $property.Value = "" }
   }
}

$data | export-csv c:\users\xxx\CSVFile.csv -NoTypeInformation  -Encoding UTF8

如果您在更改属性值之前和之后显示属性值，结果可能不会看起来有任何不同，因为

$null

和

""

都不会显示和可打印字符，但当您导出它们时，您将看到所需的输出。
