n8n Workflow: Multi-Source Tax & Cash Flow Forecasting with GPT-4, Gmail, and Google Sheets

This n8n workflow automates the process of gathering financial data from multiple sources (implied by the node types), processing it with an AI agent (likely GPT-4), and then storing or presenting the results in Google Sheets, with potential email notifications via Gmail. It aims to simplify complex financial forecasting by leveraging AI for analysis and structured output.

What it does

This workflow performs the following key steps:

1. Schedules Execution: The workflow is triggered on a predefined schedule, indicating regular, automated execution for continuous forecasting.
2. Retrieves Data (Google Sheets): It reads data from a Google Sheet, which likely serves as a primary source for financial inputs or existing records.
3. Processes Data with AI Agent: An "AI Agent" node (likely configured with GPT-4) is used to analyze the retrieved data. This agent is designed to understand and process complex financial information for forecasting.
4. Generates Structured Output: A "Structured Output Parser" is employed after the AI Agent, ensuring that the AI's analysis is formatted into a consistent, machine-readable structure (e.g., JSON), which is crucial for further automation.
5. Aggregates Data: The "Aggregate" node combines or consolidates the processed data, preparing it for storage or further action.
6. Edits Fields: The "Edit Fields (Set)" node allows for modification or transformation of the data before it's written back to Google Sheets. This could involve cleaning, reformatting, or adding new calculated fields.
7. Updates Google Sheets: The processed and structured data is then written back to a Google Sheet, presumably to update a master forecast or a reporting dashboard.
8. Sends Email Notifications (Gmail): The workflow is capable of sending emails via Gmail, which could be used to notify stakeholders about updated forecasts, report anomalies, or request further input.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running n8n instance.
• Google Account: With access to Google Sheets and Gmail for credential setup.
• OpenAI API Key: Or access to another compatible large language model for the "AI Agent" node (likely GPT-4 as suggested by the directory name).
• n8n Credentials: Configured for Google Sheets, Gmail, and your chosen AI provider (e.g., OpenAI).

Setup/Usage

1. Import the Workflow: Download the JSON provided and import it into your n8n instance.
2. Configure Credentials:
   • Set up your Google Sheets credentials to allow n8n to read from and write to your specified spreadsheets.
   • Configure your Gmail credentials for sending email notifications.
   • Set up your AI provider credentials (e.g., OpenAI API Key) for the "AI Agent" node.
3. Customize Nodes:
   • Google Sheets (Read): Specify the spreadsheet ID and sheet name from which to read your financial data.
   • AI Agent: Adjust the prompt and any specific instructions for the AI to perform the desired tax and cash flow forecasting analysis.
   • Structured Output Parser: Ensure the schema matches the expected output format from your AI agent.
   • Edit Fields (Set): Modify this node to perform any necessary data transformations or calculations.
   • Google Sheets (Write): Specify the target spreadsheet ID and sheet name where the forecast results should be written.
   • Gmail: Configure the recipient email addresses, subject, and body for your notifications.
   • Schedule Trigger: Adjust the schedule to your desired frequency for running the forecast (e.g., daily, weekly, monthly).
4. Activate the Workflow: Once configured, activate the workflow to start automated forecasting.
