How to read a csv file in Beanshell rule for Sailpoint Using Java default libraries and Opencsv

In SailPoint, BeanShell is often used for scripting within IdentityNow, particularly for custom rules. If you want to read data from a CSV file using BeanShell, you can use Java’s libraries available in SailPoint’s scripting environment. Below is an example of a BeanShell rule that reads data from a CSV file:

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

// Specify the path to your CSV file
String csvFilePath = "/path/to/your/file.csv";

// Function to read data from the CSV file
List<String[]> readCSV() {
    List<String[]> csvData = new ArrayList<>();

    try (BufferedReader br = new BufferedReader(new FileReader(csvFilePath))) {
        String line;
        while ((line = br.readLine()) != null) {
            // Split the CSV line by the comma (adjust if your CSV uses a different delimiter)
            String[] data = line.split(",");
            csvData.add(data);
        }
    } catch (IOException e) {
        e.printStackTrace();
    }

    return csvData;
}

// Call the function to read data from the CSV file
List<String[]> csvData = readCSV();

// Now you can use csvData to process the contents of the CSV file
// For example, print each row to the log
for (String[] row : csvData) {
    StringBuffer rowData = new StringBuffer();
    for (String field : row) {
        rowData.append(field).append(", ");
    }
    // Remove the trailing comma and space before printing
    logger.debug("CSV Row: " + rowData.substring(0, rowData.length() - 2));
}

// Perform further processing with the csvData as needed

Make sure to replace "/path/to/your/file.csv" with the actual path to your CSV file. Adjust the delimiter used in the split function if your CSV file uses a different delimiter.

This example reads the CSV file line by line, splits each line into fields based on the comma delimiter, and stores the data in a list of String arrays (csvData). You can then process the data as needed within your SailPoint BeanShell rule. Note that this is a basic example, and you might need to modify it based on your specific requirements and the structure of your CSV file.

Using OpenCSV

If you want to use the OpenCSV library in SailPoint’s BeanShell scripting, you’ll need to ensure that the OpenCSV library is available in your SailPoint environment. You can typically include the OpenCSV library JAR file in the classpath of your SailPoint deployment.

Assuming you have OpenCSV included in your environment, here’s an example of how you can use OpenCSV to read data from a CSV file in SailPoint’s BeanShell:

import au.com.bytecode.opencsv.CSVReader;

// Specify the path to your CSV file
String csvFilePath = "/path/to/your/file.csv";

// Function to read data from the CSV file using OpenCSV
List<String[]> readCSVWithOpenCSV() {
    List<String[]> csvData = new ArrayList<>();

    try (CSVReader reader = new CSVReader(new FileReader(csvFilePath))) {
        String[] line;
        while ((line = reader.readNext()) != null) {
            csvData.add(line);
        }
    } catch (IOException e) {
        e.printStackTrace();
    }

    return csvData;
}

// Call the function to read data from the CSV file using OpenCSV
List<String[]> csvData = readCSVWithOpenCSV();

// Now you can use csvData to process the contents of the CSV file
// For example, print each row to the log
for (String[] row : csvData) {
    StringBuffer rowData = new StringBuffer();
    for (String field : row) {
        rowData.append(field).append(", ");
    }
    // Remove the trailing comma and space before printing
    logger.debug("CSV Row: " + rowData.substring(0, rowData.length() - 2));
}

// Perform further processing with the csvData as needed

In this example, we’re using the CSVReader class from the OpenCSV library to read data from the CSV file. Make sure to replace "/path/to/your/file.csv" with the actual path to your CSV file.

Remember to check the version of OpenCSV that is compatible with your SailPoint environment and include the corresponding JAR file in the classpath. If you encounter any issues or need more advanced features, refer to the OpenCSV documentation for further details: https://opencsv.sourceforge.io/
