File contains corrupted data

Hi, 

According to my research, this issue can be caused by multiple reasons, you can have a check:

Core excel > 30MB
Excel has password
Permission issue
Corrupted model
Wrong type, error format, value issue, etc.

If you still have a problem, you can try these steps to find if they can be useful:

First, make sure the PBI desktop is the latest version.
Then please delete the data source (File -> Options and Settings -> Data Source Settings) and reconnect to see if it works.
Please make sure all permission and credentials are correct.

Thank you very much!
