1.1 Workflow description

Title: Discover & analyze n8n workflows from GitHub with OpenAI and Google Sheets
Workflow name: Discover & analyze n8n workflows from GitHub with OpenAI and Google Sheets

🧠 Overview

Discover and analyze the most valuable community-built n8n workflows on GitHub.
This automation searches public repositories, analyzes JSON workflows using AI, and saves a ranked report to Google Sheets — including summaries, use cases, difficulty, stars, node count, and repository links.

⚙️ How It Works

Search GitHub Code API — queries for extension:json n8n and splits results
Fetch & Parse — downloads each candidate file’s raw JSON and safely parses it
Extract Metadata — detects AI-powered flows and collects key node information
AI Analysis — evaluates the top N workflows (description, use case, difficulty)
Merge Insights — combines AI analysis with GitHub data
Save to Google Sheets — appends or updates by workflow name

🧩 Setup Instructions (5–10 min)

Open Config node and set:
- search_query — e.g., "openai" extension:json n8n
- max_results — number of results to fetch (1–100)
- ai_analysis_top — number of workflows analyzed with AI
- SPREADSHEET_ID, SHEET_NAME — Google Sheets target
Add GitHub PAT via HTTP Header Credential:
- Authorization: Bearer <YOUR_TOKEN>
Connect OpenAI Credential to OpenAI Chat Model
Connect Google Sheets (OAuth2) to Save to Google Sheets
(Optional) Enable Schedule Trigger to run weekly for automatic updates

> 💡 Tip: If you need to show literal brackets, use backticks like <example> (no HTML entities needed).

📚 Use Cases

1) Trend Tracking for AI Automations

Goal: Identify the fastest-growing AI-powered n8n workflows on GitHub.
Output: Sorted list by stars and AI detection, updated weekly.

2) Internal Workflow Benchmarking

Goal: Compare your organization’s workflows against top public examples.
Output: Difficulty, node count, and AI usage metrics in Google Sheets.

3) Market Research for Automation Agencies

Goal: Discover trending integrations and tool combinations (e.g., OpenAI + Slack).
Output: Data-driven insights for client projects and content planning.

🧪 Notes & Best Practices

🔐 No hardcoded secrets — use n8n Credentials
🧱 Works with self-hosted or cloud n8n
🧪 Start small (max_results = 10) before scaling
🧭 Use “AI Powered” + “Stars” columns in Sheets to identify top templates
🧩 Uses only Markdown sticky notes — no HTML formatting required

Answer BigQuery questions in Microsoft Teams with Claude 3.5 dual agents

## Quick overview Turn Microsoft Teams into a natural language BI tool. This dual-agent Claude workflow intelligently classifies user questions, generates safe BigQuery SQL, executes the query, and returns a plain-English summary alongside a data preview directly to your Teams channel. ## How it works 1. The workflow listens for new messages in a designated Microsoft Teams channel or chat. 2. It checks a 24-hour static data cache for your BigQuery schema. If the cache is missing or expired, it automatically fetches the latest INFORMATION_SCHEMA metadata. 3. A main Claude 3.5 Sonnet agent classifies the user's intent (analytical, conversational, or unsafe) and identifies the relevant database tables. 4. If the intent is analytical, a specialized Claude SQL sub-agent generates a read-only SELECT query tailored exactly to your schema. 5. The workflow executes the query against BigQuery (safely constrained to a maximum of 100 rows). 6. A final Claude agent translates the raw query results into a concise, plain-English summary. 7. The answer is posted back to Teams as an Adaptive Card, complete with a formatted data preview and the generated SQL code. 8. Non-analytical questions or pipeline errors are intelligently routed to receive standard conversational replies in Teams. ## Setup 1. CRITICAL SECURITY: Restrict your Google Cloud Service Account IAM roles to BigQuery Data Viewer and BigQuery Job User ONLY. Do not use a highly privileged account. 2. Configure your Microsoft Teams trigger and posting credentials, specifying the target team and channel for the bot to operate in. 3. Configure your Google BigQuery credentials to allow reading metadata and executing queries. 4. Configure your Anthropic credentials for the three Claude LangChain nodes. 5. Update the "Configure Variables" node with your specific GCP Project ID and BigQuery Dataset ID. ## Requirements - A Google Cloud project with BigQuery enabled and existing structured datasets. - An Anthropic API key with access to the Claude 3.5 Sonnet model. - Microsoft Teams administrator access to authorize the n8n integration. ## Customization - Distributed Environments: If you are running n8n with multiple worker nodes (Queue Mode), you must swap the $getWorkflowStaticData() schema cache logic to read/write from a dedicated Key-Value store (like Redis or Supabase) to ensure state synchronization. - UI Layout: Modify the Create Teams Adaptive Card node to add corporate branding, custom colors, or alter the FactSet data preview structure. ## Additional info This architecture features built-in pipeline protections, including strict 40,000-character payload limits to prevent LLM context window blowouts, and fallback handling for "zero-row" query results to ensure users are never left without a response.

Evaluate LinkedIn profiles with Apify and Groq Llama chat model

## Quick overview This workflow collects a LinkedIn profile URL via an n8n form, scrapes the public profile data using the Apify LinkedIn Profile Scraper actor, analyzes the results with a Groq-hosted Llama model, and displays an HTML-formatted evaluation back to the user. ## How it works 1. Receives a LinkedIn Profile URL when a user submits the n8n form. 2. Prepares the LinkedIn URL along with the Apify API token and Groq API key used for downstream requests. 3. Sends the profile URL to the Apify `harvestapi/linkedin-profile-scraper` actor and retrieves the scraped dataset items. 4. Passes the scraped profile JSON to a Groq chat model via an LLM chain to generate an HTML evaluation with a score and recommendations. 5. Displays the generated HTML evaluation to the user as the form completion message. ## Setup 1. Add a valid Apify API token and ensure the Apify actor endpoint (`harvestapi/linkedin-profile-scraper`) is accessible for your account. 2. Add Groq API credentials in n8n and confirm the selected model (meta-llama/llama-4-scout-17b-16e-instruct) is available to your Groq account. 3. Replace the placeholder API key values in the workflow (or move them to n8n credentials/environment variables) and verify the form field label matches `LinkedIn Profile URL`.

Validate startup ideas with Google Gemini, Groq, and Gmail

## Quick overview This workflow collects a startup idea via an n8n form, uses Google Gemini to generate a SWOT-style analysis, assigns a viability score, uses Groq to turn the results into a structured validation report, and emails the final report through Gmail. ## How it works 1. Receives a startup idea, industry, and target audience from an n8n Form trigger. 2. Sends the submission to Google Gemini to generate a professional analysis covering the problem, business model, and SWOT factors. 3. Generates a startup viability score (currently a random value from 80–100) and packages it with the Gemini analysis. 4. Sends the score and analysis to Groq (Llama 3.3 70B) to compile a full validation report with an executive summary, market potential, recommendations, and final verdict. 5. Emails the generated validation report to the configured recipient using Gmail. ## Setup 1. Add credentials for Google Gemini (PaLM) API, Groq API, and a Gmail OAuth2 connection. 2. Replace the placeholder recipient address in the Gmail step ("[email protected]") with your target email address before activating the workflow. 3. Publish the n8n form, then share the form URL with the users who should submit their startup ideas for validation.
