[英]Create a Specific JSON file from csv in PowerShell
我沒有使用PowerShell的經驗,因此我被要求創建此腳本來吸引我的一個朋友。 該腳本應該讀取一個csv文件(這些文件在time和host以外的其他列中是不同的,這在所有文件中都是相同的),然后將其內容輸出到以下格式的JSON文件中:
CSV文件包含以下列:
主機| 留言| 時間| 嚴重性 來源|
{
"time": 1437522387,
"host": "dataserver992.example.com",
"event": {
"message": "Something happened",
"severity": "INFO",
"source": "testapp"
#...All columns except for time and host should be under "event"
}
}
*唯一保證的列是時間和主持人。 所有其他列標題因文件而異。
這是我到目前為止的一部分:
$csvFile = Import-Csv $filePath
function jsonConverter($file)
{
#Currently not in use
$eventString = $file| select * -ExcludeProperty time, host
$file | Foreach-Object {
Write-Host '{'
Write-Host '"host":"'$_.host'",'
Write-Host '"time":"'$_.time'",'
Write-Host '"event":{'
#TODO: Put all other columns (key, values) under event - Except for
time and host
Write-Host '}'
}
}
jsonConverter($csvFile)
關於如何僅逐行提取其余列,將其內容輸出為鍵,值JSON格式(如上例)的任何想法? 謝謝!
只要您的csv看起來像這樣:
"host","message","time","severity","source"
"dataserver992.example.com","Something happened","1437522387","INFO","testapp"
這個腳本:
$filepath = '.\input.csv'
$csvData = Import-Csv $filePath
$NewCsvData = foreach($Row in $csvData){
[PSCustomObject]@{
time = $Row.time
host = $Row.host
event = ($Row| Select-Object -Property * -ExcludeProperty time,host)
}
}
$NewCsvData | ConvertTo-Json
將輸出此Json:
{
"time": "1437522387",
"host": "dataserver992.example.com",
"event": {
"message": "Something happened",
"severity": "INFO",
"source": "testapp"
}
}
如果您的Powershell版本是3.0或更高(應該):
Import-CSV $filepath | ConvertTo-JSON
完成!
