External Table Is Not In The Expected Format.

Asked By 0 points N/A Posted on -

Great day to all,

While I am working with my worksheet at office I received an error message generated by Microsoft Excel,  I pasted below the whole content of the error message for better view of my problem.

Microsoft Excel 

Step “DTSStep_DTSDataDrivenQueryTask_1” Failed

Error: 2147467259

Source: Microsoft JET Database Engine

Description: External table is not in the expected format.

Step “DTSStep_DTSDynamicPropertiesTask_1” Succeeded


As I read on the error message, it gives me a lot of head ache since I am not a technical person to understand the error, I also found nothing when I search on the internet for similar error, that is why I tried to post this issue here on techyv, hoping to get some ideas on my problem.

Thanks for reading my post.
