Hello @Siddharth Desai , Thanks for using Microsoft Q&A Platform.
Azure OpenAI On Your Data supports these following file types and formats: .txt, .md, .html, .docx, .pptx and .pdf
To upload your data, you'll need to establish a connection with a data source. When it comes to uploading files from local machine or from a blob storage account (preview), Azure AI Search is used. To learn more about the data source options I would suggest you refer to this documentation: Data source options
Is this something you are looking for?
Regards,
Vasavi
