Hi Harish,
AEM Guides supports this use case. You don’t need to manually copy-paste content from Word. Using the Word-to-DITA transformation framework in AEM Guides, you can convert Word documents into DITA type documents and then publish them to AEM pages using AEM Sites publishing.
Here’s a step-by-step guide for Word to DITA conversion: Word to DITA Transformation in AEM Guides
Hope this helps!
