It is not a direct download tool in itself, but can be used in conjunction with the Office Deployment Tool to download the full offline installer from Microsoft’s servers.

To use it, go to config.office.com in your browser, select your preferred options—such as Office suite version, architecture (32-bit or 64-bit), language, and which apps to include. Once you've configured everything, export the XML configuration file. Then, download the Office Deployment Tool from Microsoft's official site, place the XML file in the same folder, open Command Prompt, and run:

setup.exe /download configuration.xml

This will download the full Office installer to your local machine. After the download completes, run:

setup.exe /configure configuration.xml to install Office offline.
