Questions related to interacting with Google word processing Documents programmatically. Usage questions about the web application should be posted at Web Applications Stack Exchange.
Google Docs is a cloud-based application and service for creating and collaborating on word processing documents. The service supports an internal API for Google Apps Script as well as an External API.
Usage questions about the web application should be posted at Web Applications Stack Exchange or the Google Drive Help Center instead of here.
Note: Google has historically used the brand "Google Docs" to encompass a suite of products, but since conforming to that would introduce ambiguity here, the tag is specifically for word processing documents while google-apps refers to the suite.
