Power Query - Combine Binaries

[RG]

Hi guys. So ran into an issue lately, I am guessing after recent O365 updates. I have created several models based on the same csv data in single folder, and they work perfectly. Now, creating new models based on the same data, returns all the columns in one single column, meaning its concatenated. Adding new data data to the older models works perfectly, also PBID works fine. 

I also just created a few csv files in a small 30x4 grid, in order to test the combine binaries function on completely new data. Again it returs it all in one single column. 

This is very frustrating, any ideas are much appreciated. I attached a prt.scr. of what I am facing, will also attach the codes from editor mode if required.

Since the November 2016 update of Power BI Desktop, multiple object are created.

I provided an explanation in this topic.

My suggestion would be to verify your Transform Sample Binary from Data query:

by default, for csv-files the first step Source contains the function Csv.Document, including specifications for splitting values.

The next step is Promote Headers and the 3rd and last step is Change Type.

Hi thanks for your reply. I failed to point out the issue was in excel version of PQ. But given the updates to O365, your solutions are highly relevant. I'll look through those and the 21min video to better understand the sample binaries. Thank you so much.

I'm not a fan of the combine.binaries-way at all. You can still to the "old-fashioned-way" via an added column like described in here for example: http://community.powerbi.com/t5/Desktop/Retain-file-name-column-when-using-Folder-as-a-data-source-P...

Well, it turns out latest build 7766.2047 prompts for data type detection. Just like in desktop version. No worries then.
