Hello @dsl400
Sorry for the late reply.
Do I understand the scenario right, that you want to edit a file without editor interface? If so, please take a look at DocBuilder methods:Overview - ONLYOFFICE Api Documentation
For example, this one: AddText - ONLYOFFICE Api Documentation

If I misunderstood the request, please clarify it.
