Do these cells contain long text?
Besides, do you use comma character (,) separates each field of text?
Because Excel tag focuses more on general issue of Excel, such the Power Query issues, I suggest you post a new thread on following forum.
For better analysis, it's recommended to share more details in your post, such as the screenshot of your data source, and the data imported in Power Query but contain empty cells.
The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us.
Thank you for your understanding.
