n8n Google Drive Document Processing and Analytics Workflow
This n8n workflow automates the processing of documents from Google Drive, extracts data, and prepares it for further analysis, potentially involving OCR and vectorization for advanced analytics. It's designed to handle multiple documents efficiently by looping through them and aggregating results.
What it does
This workflow streamlines the process of extracting and structuring data from documents stored in Google Drive:
- Triggers Manually: The workflow is initiated manually by clicking the "Execute workflow" button.
- Fetches Documents from Google Drive: It connects to Google Drive to retrieve a list of documents.
- Loops Over Each Document: For each document found in Google Drive, the workflow processes it individually.
- Transforms Document Data: Within the loop, it uses a "Code" node to apply custom JavaScript logic, likely to extract specific fields or transform the document's metadata.
- Edits Fields: A "Set" node is used to modify or add fields to the document's data, ensuring consistency and preparing it for subsequent steps.
- Aggregates Results: After processing all documents in the loop, the "Aggregate" node combines the processed data from each document into a single output.
- Splits Out Aggregated Data: Finally, the "Split Out" node separates the aggregated data, making it ready for further use or integration with other services.
Prerequisites/Requirements
To use this workflow, you will need:
- n8n Instance: A running n8n instance (cloud or self-hosted).
- Google Drive Account: A Google Drive account with access to the documents you wish to process.
- Google Drive Credentials: Configured Google Drive OAuth2 credentials within n8n to allow the workflow to access your Google Drive.
Setup/Usage
- Import the Workflow:
- Copy the provided JSON code.
- In your n8n instance, go to "Workflows" and click "New".
- Click on the three dots menu (
...) in the top right corner and select "Import from JSON". - Paste the JSON code and click "Import".
- Configure Credentials:
- Locate the "Google Drive" node.
- Click on the "Credential" field and select your existing Google Drive OAuth2 credential or create a new one if you don't have one set up. Follow the n8n documentation for setting up Google Drive credentials if needed.
- Review and Customize Code Node:
- Examine the "Code" node to understand the JavaScript logic being applied. You may need to modify this code to fit your specific document structure and data extraction requirements.
- Customize Edit Fields (Set) Node:
- Review the "Edit Fields" node to ensure the fields being set or modified align with your desired output structure.
- Execute the Workflow:
- Once configured, click the "Execute Workflow" button to run the workflow manually. You can also activate the workflow to run on a schedule or via a webhook if you change the trigger node.

Upload large files to Dropbox with chunking & web UI progress tracking
Dropbox Large File Upload System How It Works This workflow enables uploading large files (300MB+) to Dropbox through a web interface with real-time progress tracking. It bypasses Dropbox's 150MB single-request limit by breaking files into 8MB chunks and uploading them sequentially using Dropbox's upload session API. Upload Flow: User accesses page - Visits /webhook/upload-page and sees HTML form with file picker and folder path input Selects file - Chooses file and clicks "Upload to Dropbox" button JavaScript initiates session - Calls /webhook/start-session β Dropbox creates upload session β Returns sessionId Chunk upload loop - JavaScript splits file into 8MB chunks and for each chunk: Calls /webhook/append-chunk with sessionId, offset, and chunk binary data Dropbox appends chunk to session Progress bar updates (e.g., 25%, 50%, 75%) Finalize upload - After all chunks uploaded, calls /webhook/finish-session with final offset and target path File committed - Dropbox commits all chunks into complete file at specified path (e.g., /Uploads/video.mp4) Why chunking? Dropbox API has a 150MB limit for single upload requests. The upload session API (uploadsession/start, appendv2, finish) allows unlimited file sizes by chunking. Technical Architecture: Four webhook endpoints handle different stages (serve UI, start, append, finish) All chunk data sent as multipart/form-data with binary blobs Dropbox API requires cursor metadata (session_id, offset) in Dropbox-API-Arg header autorename: true prevents file overwrites Setup Steps Time estimate: ~20-25 minutes (first time) Create Dropbox app - Go to Dropbox App Console: Click "Create app" Choose "Scoped access" API Select "Full Dropbox" access type Name your app (e.g., "n8n File Uploader") Under Permissions tab, enable: files.content.write Copy App Key and App Secret Configure n8n OAuth2 credentials - In n8n: Create new "Dropbox OAuth2 API" credential Paste App Key and App Secret Set OAuth Redirect URL to your n8n instance (e.g., https://your-n8n.com/rest/oauth2-credential/callback) Complete OAuth flow to get access token Connect credentials to HTTP nodes - Add your Dropbox OAuth2 credential to these three nodes: "Dropbox Start Session" "Dropbox Append Chunk" "Dropbox Finish Session" Activate workflow - Click "Active" toggle to generate production webhook URLs Customize default folder (optional) - In "Respond with HTML" node: Find line: <input type="text" id="dropboxFolder" value="/Uploads/" ... Change /Uploads/ to your preferred default path Get upload page URL - Copy the production webhook URL from "Serve Upload Page" node (e.g., https://your-n8n.com/webhook/upload-page) Test upload - Visit the URL, select a small file first (~50MB), choose folder path, click Upload Important Notes File Size Limits: Standard Dropbox API: 150MB max per request This workflow: Unlimited (tested with 300MB+ files) Chunk size: 8MB (configurable in HTML JavaScript CHUNK_SIZE variable) Upload Behavior: Files with same name are auto-renamed (e.g., video.mp4 β video (1).mp4) due to autorename: true Upload is synchronous - browser must stay open until complete If upload fails mid-process, partial chunks remain in Dropbox session (expire after 24 hours) Security Considerations: Webhook URLs are public - anyone with URL can upload to your Dropbox Add authentication if needed (HTTP Basic Auth on webhook nodes) Consider rate limiting for production use Dropbox API Quotas: Free accounts: 2GB storage, 150GB bandwidth/day Plus accounts: 2TB storage, unlimited bandwidth Upload sessions expire after 4 hours of inactivity Progress Tracking: Real-time progress bar shows percentage (0-100%) Status messages: "Starting upload...", "β Upload complete!", "β Upload failed: [error]" Final response includes file path, size, and Dropbox file ID Troubleshooting: If chunks fail: Check Dropbox OAuth token hasn't expired (refresh if needed) If session not found: Ensure sessionId is passed correctly between steps If finish fails: Verify target path exists and app has write permissions If page doesn't load: Activate workflow first to generate webhook URLs Performance: 8MB chunks = ~37 requests for 300MB file Upload speed depends on internet connection and Dropbox API rate limits Typical: 2-5 minutes for 300MB file on good connection Pro tip: Test with a small file (10-20MB) first to verify credentials and flow, then try larger files. Monitor n8n execution list to see each webhook call and troubleshoot any failures. For production, consider adding error handling and retry logic in the JavaScript.

When a Contact is created or updated in Zoho CRM, n8n automatically retrieves verified profile data such as LinkedIn, Twitter, Facebook and GitHub using People Data Labs β eliminating manual research and spreadsheet maintenance. Next, the workflow checks whether the contact is appearing in global News platforms (via GNews) or being discussed on Reddit. It analyzes the volume and context of these public mentions to estimate how relevant, visible or influential the person may be online. Each discovered activity contributes to a calculated Engagement Score. That score and all enrichment details are written back to Zoho CRM, helping sales and marketing teams instantly identify high-potential contacts. When the score exceeds a defined threshold, the workflow even creates a Deal automatically β meaning your CRM will notify your team of hot prospects before someone else reaches them. This safeguards missed opportunities, speeds outreach and improves your entire pipeline efficiency. π― Whoβs It For B2B sales teams & SDRs. CRM admins improving data quality.
