 This tutorial guides you through creating a Node.js-based web server that adheres to the ECF specification. By following these steps, you'll establish a connection between EIC and your target application, enabling data exchange and task execution.

+<b><u>Explanation:</u></b>
+
+This code reads role entitlement data from a Google Sheet and converts it into a JSON format suitable for ECF (External Connector Framework).
+
+Here's a breakdown of the steps:
 
+	* <b><u>Authentication:</u></b> It authenticates with the Google Sheets API using a service account.
+	* <b><u>Data Retrieval:</u></b> It retrieves data from a specified Google Sheet and defines the starting row and number of rows to read.
+	* <b><u>Header Processing:</u></b> It extracts the header row names from the sheet.
+	* <b><u>Data Processing:</u></b> It iterates through each data row and creates a role object.
+	* <b><u>Multi-valued Data Handling:</u></b> It handles comma-separated values in specific columns (child entitlements and owners) by converting them into arrays.
+	* <b><u>Output:</u></b> It converts the processed data (including offset, total count, and roles) into JSON format and logs it to the console.
+	* <b><u>Error Handling:</u></b> It includes basic error handling to log any issues during the process.
