How to import previous saved templates in new template.

Think you're missing the point of grapes. It let's you edit HTML. There's no underlying JSON format.

@nojacko I have a template which contain countdown, If I direct import as html then it changed to div so I want to import that as json and css so that component do not change to other type and also there style value preserve for clone or copy.

@YashPrince take a look at your browser local storage values, you will see what/how is stored.

Anyway, if you make a custom component and load the normal html/css, grapesjs will recognize it as the right type when you import it. The custom component type in grapesjs is usually linked to the main container id, so you do not really need a json to accomplish that.
