How gannt import from excel and ms project in local nodejs docker?

there are some requirement of import from excel and ms project in gantt, but the server has no network, so server and gantt client cannot link to dhtmlx api.js, we can create a nodejs docker to install the api.js.
so need you give me a download link of import /export excel api.js nodejs docker image.
