How to convert CSV to PDF using GroupDocs.Conversion (csv to pdf java)

Feature 1: Convert CSV to PDF with a specified delimiter

This example shows the full flow—setting a custom delimiter, initializing the converter, and producing a PDF.

Step 1: Set document and output paths

String documentPath = "YOUR_DOCUMENT_DIRECTORY/sample.csv";
String outputPath = "YOUR_OUTPUT_DIRECTORY/ConvertedCsvBySpecifyingDelimiter.pdf";

Step 2: Configure CSV load options

// Create CSV load options with specified separator
CsvLoadOptions loadOptions = new CsvLoadOptions();
loadOptions.setSeparator(','); // Use comma as the separator for parsing

Tip: Change ',' to ';' or '\t' if your source CSV uses a different delimiter.

Step 3: Initialize the Converter

// Initialize converter with specified load options
Converter converter = new Converter(documentPath, () -> loadOptions);

The lambda ensures your custom CSV settings are applied during conversion.

Step 4: Configure PDF conversion options

// Create and configure PDF conversion options
PdfConvertOptions pdfOptions = new PdfConvertOptions();

You can extend pdfOptions later to add headers, footers, or watermarking.

Step 5: Perform the conversion

// Convert the document from CSV to PDF with specified options
converter.convert(outputPath, pdfOptions);

After execution, ConvertedCsvBySpecifyingDelimiter.pdf will contain a neatly formatted PDF representation of your CSV data.

Troubleshooting tips

  • Verify that documentPath and outputPath are accessible and have correct permissions.
  • Ensure the delimiter you set matches the actual character used in the CSV file.

Feature 2: Basic CSV loading options (how to convert csv)

If you only need default parsing without a custom delimiter, the steps are even simpler.

Step 1: Set document path

String documentPath = "YOUR_DOCUMENT_DIRECTORY/sample.csv";

Step 2: Configure basic load options

// Create and configure basic CSV load options
CsvLoadOptions csvLoadOptions = new CsvLoadOptions();
csvLoadOptions.setSeparator(','); // Default separator

These settings can be tweaked for multi‑line fields or quoted values.

Performance considerations for batch convert csv pdf

  • Memory management – Adjust JVM heap (-Xmx) when processing large files.
