Google BigQuery and NocoDB integration

Overview This n8n workflow automatically retrieves the monthly CrUX (Chrome User Experience) Report from Google BigQuery and updates the data in NocoDB. It removes the previous month’s data before inserting the new dataset, ensuring your database always contains the latest CrUX rankings for website origins. The flow is fully automated, using schedule triggers to handle both data cleanup and data insertion each month. ✅ Tasks ⏰ Runs automatically on a monthly schedule 🔢 Converts the month name to a numeric value for table selection 🧹 Deletes last month’s CrUX data from NocoDB 🌐 Queries Google BigQuery for the latest monthly dataset 💾 Inserts the new CrUX rankings into NocoDB ⚙️ Keeps your database up to date with zero manual effort 🛠 How to Use 1️⃣ Set Up BigQuery Access Connect your Google BigQuery credentials. Make sure your project includes access to the chrome-ux-report public dataset. 2️⃣ Adjust the Query In the Google BigQuery node, change the LIMIT value to control how many top-ranked sites are retrieved. Ensure the {{ $json.table }} field correctly references the dataset for the desired month (e.g., 202509). 3️⃣ Prepare NocoDB Table Create a table in NocoDB with fields: origin, crux_rank, and any additional metadata you wish to track. 4️⃣ Schedule Automation The workflow includes two Schedule Trigger nodes: One runs the data cleanup process (deletes last month). One runs the data insertion for the new month. 5️⃣ Run or Activate the Workflow Activate it to run automatically each month. You can also run it manually to refresh data on demand. 📋 Prerequisites Before running this workflow, make sure you complete the following setup steps: 🧱 Enable BigQuery API Go to Google Cloud Console → APIs & Services Enable the BigQuery API for your project. 📊 Access the Chrome UX Report Dataset In BigQuery, search for “Chrome UX Report” in the Marketplace or go directly to: https://console.cloud.google.com/marketplace/product/chrome-ux-report/chrome-ux-report Click “View Dataset” and add it to your BigQuery project. 🔑 Connect BigQuery to n8n In n8n, create credentials for your Google BigQuery account using Service Account Authentication. Ensure the account has permission to query the chrome-ux-report dataset. 🗄️ Create a NocoDB Table In NocoDB, create a new table to store your CrUX data with the following fields: origin → Short text crux_rank → Number ⚙️ Connect NocoDB to n8n Use your NocoDB API Token to connect and allow the workflow to read/write data. What is CrUX Rank? CrUX Rank (Chrome User Experience Rank) is a metric from Google’s Chrome UX Report (CrUX) dataset that indicates a website’s popularity based on real user visits. It reflects how frequently an origin (website) is loaded by Chrome users around the world. A lower rank number means the site is more popular (e.g., rank 1 = top site). The data is collected from anonymized Chrome usage statistics, aggregated monthly. This rank helps you track site popularity trends and compare your domain’s visibility over time.
