+ServiceNow MID Server CSV Reader
+
+This utility enables reading CSV files from MID Server machines through the ECC Queue mechanism.
+
+Overview
+
+The solution uses a Script Include named CSVReaderUtil.js to send and receive data between the ServiceNow instance and the MID Server.
+It supports executing read operations on local CSV files stored on the MID Server filesystem.
+
+Steps to Use
+
+Create the Script Include
+Create a new Script Include named CSVReaderUtil.js in ServiceNow.
+This Script Include handles communication with the MID Server and parsing of CSV data.
+
+Trigger the Script from a Background Script
+
+Use the following example to read data from a CSV file located on the MID Server:
+
+var csvUtil = new CSVReaderUtil();
+
+// Send probe to the MID Server to read the CSV file
+var probeId = csvUtil.readCSVFile('/path/to/your/file.csv');
+
+// Wait a few seconds to allow the MID Server to process the request
+gs.sleep(5000);
+
+// Retrieve the response from the ECC Queue
+var csvData = csvUtil.getCSVResponse(probeId);
+
+gs.info('CSV Data: ' + csvData);
