Convert CSV to PDF in Java

The following are the steps to convert a CSV file to PDF:

• Create an instance of Workbook class.
• Load the CSV file using Workbook.loadFromFile(filePath, separator) method.
• Set the worksheet to be rendered to one PDF page using Workbook.getConverterSetting().setSheetFitToPage(true) method.
• Get the first worksheet in the Workbook using Workbook.getWorksheets().get(0) method.
• Loop through the columns in the worksheet and auto-fit the width of each column using Worksheet.autoFitColumn() method.
• Save the worksheet to PDF using Worksheet.saveToPdf() method.

import com.spire.xls.Workbook;
import com.spire.xls.Worksheet;

public class ConvertCsvToPdf {
    public static void main(String []args) {
        //Create a Workbook instance
        Workbook wb = new Workbook();
        //Load a CSV file
        wb.loadFromFile("Sample.csv", ",");

        //Set SheetFitToPage property as true to ensure the worksheet is converted to 1 PDF page
        wb.getConverterSetting().setSheetFitToPage(true);

        //Get the first worksheet
        Worksheet sheet = wb.getWorksheets().get(0);

        //Loop through the columns in the worksheet
        for (int i = 1; i < sheet.getColumns().length; i++)
        {
            //AutoFit columns
            sheet.autoFitColumn(i);
        }

        //Save the worksheet to PDF
        sheet.saveToPdf("toPDF.pdf");
    }
}
