Hi Lokesh,
Thanks for your question.
After I run your script, I got the result as you. When I tried to delete ".select()", it got the result you wanted.
So you can try to change you script.
$found= $doc.Range($startPosition, $endPosition)
$found | Out-File "D:\test\Found2.txt" -Force
If you want to save it to CSV file, you can change the extension to .csv file.
I found the link about the word paragraph range and selection object below.
click it
Best Regards,
Lee
Just do it.
