How to append data into a CSV file using PowerShell?
To append the data into CSV file you need to use –Append parameter while exporting to the CSV file.
In the below example, we have created a CSV file
Example
$outfile = "C:\temp\Outfile.csv"
$newcsv = {} | Select "EMP_Name","EMP_ID","CITY" | Export-Csv $outfile
$csvfile = Import-Csv $outfile
$csvfile.Emp_Name = "Charles"
$csvfile.EMP_ID = "2000"
$csvfile.CITY = "New York"
$csvfile | Export-CSV
$outfile Import-Csv $outfileNow we need to append the below data to the existing file. So first we will import the csv file into a variable called $csvfile
$csvfile = Import-Csv $outfile $csvfile.Emp_Name = "James" $csvfile.EMP_ID = "2500" $csvfile.CITY = "Scotland"
Once data is inserted into a variable, we will append data with –Append parameter.
$csvfile | Export-CSV $outfile –Append
Check the output:
Import-Csv $outfile
Output
EMP_Name EMP_ID CITY -------- ------ ---- Charles 2000 New York James 2500 Scotland
