Extract data from PDF forms Leave feedback

GroupDocs.Parser allows to parse form data from PDF documents.

To extract PDF form data call the parseForm() method:

parser.parseForm(); // returns DocumentData or null

This method returns an instance of the DocumentData class with the extracted data, or null if form parsing isn’t supported for the document.

Here are the steps to parse a form of the document:

• Instantiate the Parser object for the initial document;
• Call the parseForm() method and obtain the DocumentData object;
• Check if data isn’t null (parse form is supported for the document);
• Iterate over field data to obtain form data.

A field value is returned as a page area. Text values are PageTextArea objects. Use java.instanceOf(object, className) from the java package to check the Java type of a value (the JavaScript instanceof operator doesn’t work with Java objects).

The following example shows how to parse a form of the document:

const java = require('java');
const groupdocs = require('@groupdocs/groupdocs.parser');

// Create an instance of Parser class
const parser = new groupdocs.Parser('Forms.pdf');
try {
  // Extract data from PDF document
  const data = parser.parseForm();
  // Check if form extraction is supported
  if (data === null) {
    console.log("Form extraction isn't supported.");
  } else {
    // Iterate over extracted data
    for (let i = 0; i < data.getCount(); i++) {
      const field = data.get(i);
      const area = field.getPageArea();
      // Check if the field value is a text area
      const isTextArea = area !== null && java.instanceOf(area, 'com.groupdocs.parser.data.PageTextArea');
      console.log(`${field.getName()}: ${isTextArea ? area.getText() : 'Not a template field'}`);
    }
  }
} finally {
  parser.close();
}

process.exit(0);
