To extract useful information from XLSX documents in your Java projects using GroupDocs.Parser, follow these instructions:
// Initialize your Parser with the input document
try (Parser parser = new Parser("input.xlsx"))
{
// Retrieve all available text content from the document
try (TextReader reader = parser.getText())
{
// If no text is found, the return value will be null
// Incorporate the extracted content into your solution
System.out.println(reader == null ?
"This format may not support text extraction" : reader.readToEnd());
}
}

GroupDocs.Parser does more than just text extraction—it supports full parsing of barcodes, metadata, images, tables and other data to power intelligent automation and data-driven applications.
Access data like text, tables, and media from widely used file types such as PDF, Word, Excel, PowerPoint, HTML, and others.
Process content from both native digital files and scanned images, using OCR when necessary to interpret embedded text.
Tailor your parsing with settings for page selection, layout zones, and custom field templates to meet specific extraction needs.
This sample shows how to extract structured fields from a PDF using a custom template via GroupDocs.Parser.
// Open the PDF using the Parser class
try (Parser parser = new Parser("input.pdf"))
{
// Apply the parsing template to extract defined data
DocumentData data = parser.parseByTemplate(GetTemplate());
// Check if the template-based extraction is available
if (data == null) {
return;
}
// Work with the extracted data fields
for (int i = 0; i < data.getCount(); i++) {
System.out.print(data.get(i).getName() + ": ");
PageTextArea area = data.get(i).getPageArea() instanceof PageTextArea
? (PageTextArea) data.get(i).getPageArea() : null;
System.out.println(area == null ? "Not a template field" : area.getText());
}
}
private static Template GetTemplate()
{
// Define detector settings for extracting the 'Details' section
TemplateTableParameters detailsTableParameters =
new TemplateTableParameters(new Rectangle(new Point(35, 320), new Size(530, 55)), null);
TemplateItem[] templateItems = new TemplateItem[]
{
new TemplateTable(detailsTableParameters, "details", null)
};
Template template = new Template(java.util.Arrays.asList(templateItems));
return template;
}
