If I try to duplicate a page template from the code editor, the data will be duplicated because data is saved inside sections, so I’ll have to manually duplicate all the sections within a template as well.
Is there an easier way about it? Which duplicate pages and sections? In other words, duplicating pages without copying the data?
Sorry you are facing this issue, it would be my pleasure to help you.
Welcome to the Shopify community! 
Thanks for your good question.
can you please create separate page template and section you can do this so doesn’t data copy other pages
Yes I know that, but most templates have too many sections, it’s a hassle to copy all of them
Thanks for details yes not all but as you like section copy and past
