Hi @Santosh J
Welcome to Microsoft Q&A platform.
Thank you for reaching out and sharing your query about the data preview issue in Azure Data Factory (ADF) debug mode. We understand your concern and appreciate the screenshot you’ve shared.

Based on our analysis and discussions with the internal team, here are a few details and steps to address this:

Cause of the Issue: The issue occurs when there are numerous columns in the dataset, and the available screen size is insufficient to display the data preview clearly.

Steps to Mitigate: Please try refreshing your browser and retrying the operation. This often resolves the issue. If the issue persists, you may consider testing the same scenario in Azure Synapse Analytics, where improvements are actively being worked on to enhance visibility.

This issue has been fully addressed in Azure Data Factory (ADF). For Synapse Analytics, a fix is underway and should mitigate similar concerns in the near future.

If you continue to experience difficulties or have additional questions, please feel free to reach out, and we’ll be happy to assist further.

Hope this helps. Do let us know if you any further queries.
