Getting Started

• Java Runtime Environment (JRE) 8 or later; JRE 17 or later is required for APIs that take callbacks implemented in JavaScript (e.g. page previews)
• Windows, Linux, or macOS

Installation

To install the package, check the System Requirements and Installation documentation topics for platform-specific instructions.

npm install @groupdocs/groupdocs.parser

Use cases

Here are some typical use cases:

Extract text

This example shows how to extract a text from a DOCX file.

'use strict';

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

// Apply license, required for non-evaluation usage
const license = new groupdocs.License();
license.setLicense("GroupDocs.Parser.lic");

// Extract text
const parser = new groupdocs.Parser("document.docx");
const reader = parser.getText();
if (reader === null) {
  console.log("Text extraction isn't supported");
} else {
  console.log(reader.readToEnd());
  reader.close();
}
parser.close();

// Exit
process.exit(0);

Extract metadata

This example prints the metadata of a DOCX file.

'use strict';

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

const parser = new groupdocs.Parser("document.docx");

// Iterate over metadata items
const iterator = parser.getMetadata().iterator();
while (iterator.hasNext()) {
  const item = iterator.next();
  console.log(`${item.getName()}: ${item.getValue()}`);
}

parser.close();
process.exit(0);

Parse PDF form fields

This example reads the values of all form fields of a PDF document.

'use strict';

const java = require('java');

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

const parser = new groupdocs.Parser("form.pdf");

// Extract form data
const data = parser.parseForm();
for (let i = 0; i < data.getCount(); i++) {
  const field = data.get(i);
  const area = field.getPageArea();
  const isText = area !== null && java.instanceOf(area, 'com.groupdocs.parser.data.PageTextArea');
  console.log(`${field.getName()}: ${isText ? area.getText() : "Not a text field"}`);
}

parser.close();
process.exit(0);
