只從int值中刪除csv文件中的前導零僅

Question

我有這個csv文件我試圖刪除前導零，但與我的代碼爲任何數字有字母或特殊字符，它沒有價值，我不想說......

現在我用下面的代碼刪除前導零...

Write-Host "Removing leading zeros from column `"column1`" in C:\path\test.csv" 
Import-Csv "C:\path\test.csv" | 
    select -Property @{n='column1';e={[int]$_.column1}},* -Exclude 'column1' | 
    Export-Csv "C:\path\testtemp" -NoTypeInformation 
Move-Item "C:\path\testtemp" "C:\path\test.csv" -Force 
Write-Host "Complete" 

的問題是在字符串（用字母和特殊字符）可能不會被轉換爲[int]，它們會被移除，如下所示...

我已經試過到目前爲止...

我曾嘗試編輯代碼如下...

Write-Host "Removing leading zeros from column `"column1`" in C:\path\test.csv" 
Import-Csv "C:\path\test.csv" | 
    select -Property @{n='column1';e={If(([int]$_.column1 -ne $null) -or ([int]$_.column1 -ne "")){[int]$_.column1}Else{$_.column1}}},* -Exclude 'column1' | 
    Export-Csv "C:\path\testtemp" -NoTypeInformation 
Move-Item "C:\path\testtemp" "C:\path\test.csv" -Force 
Write-Host "Complete" 

但是不添加的結果非int值仍然是相同的。如果任何人都可以幫助我的語法，我會很感激。

Answer 1

嘗試使用「.TrimStart（）」取出零。

Import-CSV "C:\path\test.csv" | ForEach-Object{ 
    $_.column1 = ($_.column1).TrimStart('0') 
    $_ 
} | Export-Csv "C:\path\test2.csv" -NoTypeInformation 
Move-Item "C:\path\test2.csv" "C:\path\test.csv" -Force 

請注意，爲了這個工作，我不得不重新格式化您的第一列以取出額外的空間。因此，原始csv中的標題將以： column1，column2等開頭。
