Read and Modify Properties

This guide will show you how to Read and Modify Properties of a Microsoft Word Document.

Before you begin

You should get your API key from your UniCloud account.

If this is your first time using UniOffice SDK, follow this guide to set up a local development environment.

Clone the project repository

In your terminal, clone the examples repository. It contains the Go code we will be using for this guide.

git clone

To get the example navigate to the path document/doc-properties folder in the unioffice-examples directory.

cd unioffice-examples/document/doc-properties/

How it works

Lines 5-13 import the UniOffice packages and other required dependencies.

The init function in lines 15-22 authenticates your request with your UNIDOC_LICENSE_API_KEY.

In the main function, the file is opened, with error handling on lines 25-29. Next, the CoreProperties function is used to access the document properties on lines 33-40, which can be conveniently obtained using the result variable.

Additionally, these properties can be modified using the corresponding configure method associated with each property, as demonstrated on lines 43-49, just before saving the file.

Run the code

Run this command to generate a Word document that displays the changes applied to its custom properties.

go run main.go

Sample output

When you inspect the properties of the document, you will notice that they align with the properties assigned in the code, reflecting the alterations displayed on the screen via the printf statements.
