How to read barcodes from Ods in Java

With GroupDocs.Parser, Java developers can extract barcodes from ODS documents in just a few steps:

Load the ODS document using Parser.
Verify the document supports barcode extraction.
Use the API to retrieve barcode data.
Loop through the barcode results and apply them as needed.

Copy

// Open a document containing barcodes using Parser
try (Parser parser = new Parser("input.ods"))
{
    // Check barcode support for the file
    if (!parser.getFeatures().isBarcodes())
    {
        System.out.println("Handle unsupported file types");
        return;
    }

    // Extract and use barcode data
    Iterable<PageBarcodeArea> barcodes = parser.getBarcodes();
    for(PageBarcodeArea barcode : barcodes)
    {
        System.out.println("Page: " + barcode.getPage().getIndex());
        System.out.println("Value: " + barcode.getValue());
    }
}

More parsing capabilities

GroupDocs.Parser goes beyond barcode extraction—it also lets you extract plain text, images, and structured elements to support data-driven workflows.

Wide barcode format support

Detect standard barcode formats including QR Code, Code 39, Data Matrix, EAN, Aztec, and others.

Read barcodes from multiple sources

Extract barcode information from Office documents, PDFs, and image files like PNG, JPG, and BMP.

Custom barcode reading setup

Fine-tune barcode extraction with options for targeting specific regions and multi-page files.

Example: extract barcodes from PDF with options

This sample demonstrates barcode extraction from a PDF document using custom settings.

Java

//  Initialize parser with PDF document
try (Parser parser = new Parser("input.pdf"))
{
    // Ensure the document supports barcode reading
    if (!parser.getFeatures().isBarcodes())
    {
        return;
    }

    // Apply filtering with barcode options
    BarcodeOptions options = new BarcodeOptions(QualityMode.Low, QualityMode.Low, "QR");

    // Extract barcodes using the parser
    Iterable<PageBarcodeArea> barcodes = parser.getBarcodes(options);

    // Handle each barcode result
    for (PageBarcodeArea barcode : barcodes)
    {
        System.out.println("Page: " + String.valueOf(barcode.getPage().getIndex()));
        System.out.println("Value: " + barcode.getValue());
    }
}
