Implementation Guide

Convert CSV to PDF with Advanced Options

Using advanced options ensures your data retains its integrity during conversion, maintaining original formatting for date-time and numerical values.

Step-by-Step Implementation

1. Configure Load Options Start by setting up CsvLoadOptions to handle special data types:

// Initialize load options for the CSV
CsvLoadOptions loadOptions = new CsvLoadOptions();
loadOptions.setConvertDateTimeData(true); // Enable conversion of date-time data
loadOptions.setConvertNumericData(true);  // Enable conversion of numeric data

2. Create a Converter Object Initialize your Converter object with the input CSV file path and load options:

String inputCsvPath = "YOUR_DOCUMENT_DIRECTORY/sample.csv";
Converter converter = new Converter(inputCsvPath, () -> loadOptions);

3. Set Up PDF Conversion Options Prepare to convert your document by configuring PdfConvertOptions:

// Initialize PDF conversion options
PdfConvertOptions pdfConvertOptions = new PdfConvertOptions();

4. Execute the Conversion Finally, perform the conversion and save the output PDF file at the desired location:

String outputPdfPath = "YOUR_OUTPUT_DIRECTORY/converted_file.pdf";
converter.convert(outputPdfPath, pdfConvertOptions);

Troubleshooting Tips

  • Missing Dependencies: Ensure Maven dependencies are correctly resolved. Running mvn clean install can help.
  • File Path Issues: Double-check the paths to your input CSV and output PDF files for correctness.

Practical Applications

  1. Business Reporting: Convert monthly sales data from CSV to PDF for business meetings.
