Problem importing a folder to Power BI

[SIH007]

Hi, I have a very strange issue:

today I wanted to import for Excel files (complete folder, no other files, etc). I kept getting the error message

What is so strange about it is that I had that issue 2 weeks ago already. When I tried to import the very same folder the next day it worked without any problems. Can anyone tell me the reason for it? I am sure, tomorrow it will work fine again.

Best regards,

Susanne

Hi @SIH007 ,

Over the past few days, Power BI has experienced a temporary service outage that may have led to this issue.

I can't accurately identify the error message in the sample picture above.

Since it's an English surpport fourm,if you can show the picture in English.We may provide better help.

Best regards.

ok, if it helps, the problem still persists:

I found the source of the problem: The files in the folder had different tab-names. If you can't guarantee that all files have the same tab names you have to modify the M-text
