Tools that add features and functionality to Confluence pages.

Confluence macros are pre-built blocks of code that you can add to pages to accomplish certain tasks.  Macros can:

• Aggregate and display content from other areas of your site;
• Surface information such as page metadata, user info, etc.;
• Provide different display options for content and data;
• Render links and other calls to action; and more.

Most macros have parameters that you can set to further customize a macro's output.

Please see 

Many apps from the Atlassian Marketplace are bundled with additional macros.
