Unable to load file into table.

Question

Unable to load file into table.

Ashley Smith (Accenture Federal Services LLC) 45 Microsoft External Staff

I'm not able to upload a local csv file into a table. I'm able to click Get Data, choose Local file, and upload the file, but after I click Next to go to the Ingest screen, it closes out of the window all together preventing me from ingesting the file. I perform this action each day and have not had issues in the past. I am part of a security group that has read write access to the cluster so it shouldn't be a permissions issue.

It sounds like you're encountering an unexpected issue during the file ingestion process, especially since it was working fine until recently. Given that you're able to upload the file and reach the "Next" step, but the window closes unexpectedly, this could be caused by a few things:

Here are few suggested troubleshooting steps that might help you:

Try a different browser (e.g., Chrome, Edge, Firefox) to rule out any browser-specific behavior.
Clear browser cache or use an incognito/private window, in case stored session data is interfering.
Test with a different file, such as a small sample CSV, to see if the issue is specific to this file.
If supported in your environment, try ingesting from an Azure Blob or ADLS location instead of local file upload, as a temporary workaround.

Since your access hasn’t changed and you're part of the appropriate security group, this may be a UI or backend regression in the platform.

To help us investigate further:

What platform or tool are you using to perform the upload?
Are there any error messages displayed when the window closes?
Has anything changed recently in your environment (like updates or new policies)?
Can you confirm if this issue occurs with all CSV files or just specific ones?

I hope this information helps. Please do let us know if you have any further queries.

Thanks for your response!

I am using Azure Data Explorer on the web to perform this upload. No error messages pop up when the window closes. There weren't policy changes that I'm aware of or can find documentation on. We tried multiple CSV files so it does not seem specific to just one.

Since you're using Azure Data Explorer on the web and the ingestion window closes without any error message, even across multiple CSV files, this could point to a frontend or session-related issue.

Here are a few steps to help troubleshoot further:

Recommended Actions:

Try in Incognito/Private browsing mode - This helps rule out cached session data or extension interference that might be affecting the web UI.

Check browser console logs - Before the window closes, press F12 to open Developer Tools, go to the Console and Network tabs, and look for any errors or failed requests. These details can help isolate what’s going wrong behind the scenes.

Test another browser - Sometimes browser-specific updates or extensions can cause unexpected behavior. If possible, try the same steps in Chrome, Edge, or Firefox.

Try another machine or network - If you're able to, try from a different machine or internet connection. This can rule out local device or network-level issues (like security policies or pop-up blockers).

Use an alternate ingestion method (as a temporary workaround) - If needed urgently, you can try using .ingest via the ADX Query window, or upload the CSV to Blob Storage and ingest it from there.

For additional information, please refer: .ingest into

I hope this information helps.
