How to use Graph API to edit Word or PowerPoint content

Question

How can I use the Microsoft Graph API to extract content from a Word or PowerPoint document, find and replace specific text, and then update the existing document? I have attempted to use https://graph.microsoft.com/v1.0/me/drive/items/{drive-item-id}/content, but the content is in a non-readable format.

Hi @Satya Revanth Kumar Majji (AU) ,Thanks for reaching out.

The content endpoint on drive item returns a stream. In order to edit a word or PowerPoint document you need to use some library to get the document from a stream. one such popular third party library is Aspose. You can load the document using aspose and edit it programmatically.

Once the document is edited you can save it and upload it by using graph api (in the upload api of the graph use conflict behavior as replace)

Answer 2

Do you know what kind of stream this is?

I have several suggestions from copilot/chatGPT to deal with the "stream" but it is unclear whether its a binary stream, a byte stream or something else...
