This guide shows how to Java WordsApi can be used to extract metadata from a Word DOCX document — a quick way to read document properties without any third‑party tools. For format details, see the DOCX file info page on kb.fileformat.app.

Prerequisite

  • Create an account and get API credentials
  • Download the Aspose.Words Cloud SDK for Java from the official repository to work with Word document properties
  • Set up a Java project and add the SDK as a dependency to enable metadata retrieval

Steps to Fetch Document Properties in Word with Java REST API

  1. Instantiate the Configuration object by setting the ClientId and ClientSecret.
  2. Create the WordsApi class object using the Configuration object.
  3. Read the input Word file into a byte array.
  4. Create the GetDocumentPropertiesOnlineRequest request object for reading the metadata.
  5. Invoke the GetDocumentPropertiesOnline() method to fetch the properties.
  6. Parse through all the properties in the API response and display the information.

These steps outline the development of a Word DOCX metadata viewer with Java REST API. First, instantiate the WordsApi with your credentials, then load the Word document into a byte array. Next, build the request using GetDocumentPropertiesOnlineRequest and call GetDocumentPropertiesOnline() to obtain the document properties.
