Description:

  1. Overview
    This workflow generates automated revenue and expense comparison reports from a structured Google Sheet. It enables users to compare financial data across the current period, last month, and last year, then uses an AI agent to analyze and summarize the results for business reporting.

  2. Prerequisites
    A connected Google Sheets OAuth2 credential.

A valid DeepSeek AI API (or replaceable with another Chat Model).

A sub-workflow (child workflow) that handles processing logic.

Properly structured Google Sheets data (see below).

  1. Required Google Sheet Structure
    Column headers must include at least: Date, Amount, Type.

  2. Setup Steps
    Import the workflow into your n8n instance.

Connect your Google Sheets and DeepSeek API credentials.

Update:

Sheet ID and Tab Name (already embedded in node: Get revenual from google sheet).

Custom sub-workflow ID (in the Call n8n Workflow Tool node).

Optionally configure chatbot webhook in the When chat message received node.

  1. What the Workflow Does
    Accepts date inputs via AI chat interface (ChatTrigger + AI Agent).

Fetches raw transaction data from Google Sheets.

Segments and pivots revenue by classification for:

Current period

Last month

Last year

Aggregates totals and applies custom titles for comparison.

Merges all summaries into a final unified JSON report.

  1. Customization Options
    Replace DeepSeek with OpenAI or other LLMs.

Change the date fields or cycle comparisons (e.g., quarterly, weekly).

Add more AI analysis steps such as sentiment scoring or forecasting.

Modify the pivot logic to suit specific KPI tags or labels.

  1. Troubleshooting Tips
    If Google Sheets fetch fails: ensure the document is shared with your n8n Google credential.

If parsing errors: verify that all dates follow the expected format.

Sub-workflow must be active and configured to accept the correct inputs (6 dates).
