Hi @VARINA1234, thanks for your post!  The 'Refresh Dataset' feature is only available for datasets imported from Google Sheets, which maintains a dynamic, live connection with Lucidchart, and a live integration with Onedrive is not currently supported. When using Excel files as your data source, the recommended approach is to utilize the 'Replace Dataset' option to update the linked data in your document - “Refresh Dataset” is not available.

However, we’re very interested in your feedback and committed to continually improving our products. If you’re willing to share, we’d love to hear more details about your use case or what you’d like to see in this experience within this thread. I’ve also converted this post to an idea so that it’s visible to others within the Product Feedback section of the community - from here, they can upvote it and add details of their own.

Finally, for more information on how Lucid manages feedback via this community, take a look at this post:
