Hello,
How to insert 10 webparts into multiple pages at a time automatically(not manual). Can anyone please help me how to do this?
You can use powershell to add webpart in sharepoint pages. You can write a function in powershell script and pass teo parameters like page url and the webpart name . You need to have your webpart file in a location from where you need to read the webpart in the powershell script .
