About This Workflow
Overview
This n8n workflow is designed to automate the creation of professional HTML reports from various data inputs. It begins by receiving data via a Webhook. This data is then processed by an AI Consultant node, which analyzes the input and formulates a structured report outline based on predefined system prompts.
Subsequently, the o3 and Sonnet 4.5 nodes further process this information, potentially for refinement or to generate specific content elements. The core of the report generation lies in the 'Style Agent' node, which takes the processed information and transforms it into a complete, email-compatible HTML document. This agent is heavily guided by a detailed system prompt that dictates HTML structure, inline CSS, and formatting rules to ensure the output is professional and ready for immediate use.
Finally, the generated HTML content is sent to a Gmail account using the 'Send a message' node. This workflow solves the problem of manually creating and formatting reports, saving time and ensuring consistency in branding and presentation. It's ideal for recurring reports, data summaries, or any scenario where structured, visually appealing output is required efficiently.
