Create an Excel file using PowerShell script

Here is a code to write data into Excel file and save it in a particular path.

$excel = New-Object -ComObject excel.application

#$excel.visible = $True

$workbook = $excel.Workbooks.Add()

$SheetName = "MySheet"

$uregwksht= $workbook.Worksheets.Item(1)

$uregwksht.Name = $SheetName

$row = 1

$Column = 1

$uregwksht.Cells.Item($row,$column)= "Column Title"

for ($i = 2; $i -le 5; $i++)

{

Write-Output $i

$row = $row + 1

$uregwksht.Cells.Item($row,$column)= "Abcd" + $i

}

$outputpath = "D:\test.xlsx"

$excel.displayalerts = $false

$workbook.Saveas($outputpath)

$excel.displayalerts = $true

Write-Output $("File saved on " + $outputpath )

$excel.Quit()

Insert - Update SQL Database using Powershell Script

Here is example of SQL Server database insert and update transaction using Powershell script function

SQL table

CREATE TABLE [dbo].[BackupLog](
 [Id] [int] IDENTITY(1,1) NOT NULL,
 [BackupDetail] [nvarchar](500) NOT NULL,
 [StartTime] [datetime] NULL,

PRIMARY KEY CLUSTERED 
(
 [Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

Insert Record

function InsertRecord($con)
{

  "SELECT SCOPE_IDENTITY() as [InsertedID]; "

 # Define SQL Parameters 
 $sqlCommand.Parameters.Add((New-Object Data.SqlClient.SqlParameter("@BackupDetail",[Data.SQLDBType]::NVarChar, 500))) | Out-Null
 $sqlCommand.Parameters.Add((New-Object Data.SqlClient.SqlParameter("@StartTime",[Data.SQLDBType]::DateTime2))) | Out-Null
 $sqlCommand.Parameters.Add((New-Object Data.SqlClient.SqlParameter("@EndTime",[Data.SQLDBType]::DateTime2))) | Out-Null
  
 # Set Parameters Value
 $sqlCommand.Parameters[0].Value =  get-date
 $sqlCommand.Parameters[1].Value = get-date
 $sqlCommand.Parameters[2].Value = get-date

 # Run the query and get the scope ID back into $InsertedID
 $InsertedID = $sqlCommand.ExecuteScalar()
 return $InsertedID
}

Update Record

function UpdateRecord($con, $recordId)
{
 ############  Update Record  ############
 $sqlCommandUpdate = New-Object System.Data.SqlClient.SqlCommand

 # Set Parameters Value
 $sqlCommandUpdate.Parameters[0].Value = get-date
 
 # Run the query and get the scope ID back into $UpdatedID
 $sqlCommandUpdate.ExecuteScalar() 
}

Powershell Script

cls
 
#SQL connection Configuration
$DBServer = "localhost"
$DBName = "DBName"

# Create SQL Connection object
$sqlConnection = New-Object System.Data.SqlClient.SqlConnection

$sqlConnection.Open()

# Quit if the SQL connection didn't open properly.
if ($sqlConnection.State -ne [Data.ConnectionState]::Open) 
{
    "There is something wrong in connection string"    
}
else
{

 $newid = InsertRecord -con $sqlConnection 
 # Write to the console.
 "Inserted row ID = $newid"  
 
 #wait for 5 second
 Start-Sleep -s 5
 UpdateRecord -con $sqlConnection -recordId $newid
  
 # Close SQL Connection
 $sqlConnection.Close()
}

Hope this will help you and save your time.
