I don't understand why this channel isn't bigger, seeing that the solutions he gives is by far explained in such a way that most people understand. Keep up the good work Sir.

Wanted to let you know this proved useful to me. My case was far more complex and I had to debug somethings...but it worked! Saves me like 90 minutes of work.

Hi, thank you for such a clear explanation. I hope you can help, not many people talk about this, but can we load each table as a separate data table? Or is it possible to horizontally combine all the tables if the date column is the same in all tables loaded here?

I am sure this is helpful to the excel experts. As a layman, I wanted step by step solution. Like starting right with the mapping tables. Everything was already created earlier, so i could not understand anything.

This rocks! Thank you for a great explanation on this topic!

This was an EXCELLENT tutorial, thank you so much.

This is soo amazingly helpful! Thank you!

Thank you so much! Easy and effective solution .

You're a lifesaver, I'm just getting started into Query logic and your channel has been tremendously helpful!

wonderful really, I had a tough time playing around inconsistent columns. A big thankyou 🙂

Hey Chandeep, thanks for the really good videos. It's really fun to listen to you and above all you explain everything really well. Keep up the good work!

You are a MASTER of excel. Glad that I found your channel and is really informative/educational and highly useful. This channel deserves a millions of subscribers 🎉❤😊

Thank you Chandeep. This is a common challenge faced while working with different data sets.

This was great as always. I have been doing this another way without Table.Combine and List function.I need to wrap my head around Table.Combine and List as this would make it more dynamic.

Thank you very much. I was working on such exercise since last 2 weeks and struggle a lot , referred many You tube videos but.... Hats up to you dear ...which helped to proceed further ..Very well explained ....

Thank you for this tutorial...it's the perfect solution to the issue we are having with 100+ columns.

I'm going to try this in my next assignment! Thank you! For the potential risk of wrongly aligned mapping table after a new file with new headers getting added, I wonder if a better way of doing it is to create a mapping table to be left joined to the dynamic column header table? It will still shows empty if a new table with new header gets added, but at least it won't map to the wrong thing after refreshed.

Agree, Outstanding. NOTE: The Sales Data folder in the Zip file has two temporary files - names starting with ~ that are hidden and causing an error in the M Code. Just delete them to fix it. Also, change the folder path in the FolderLocation query, not the Data Source.

This video is really GREAT. Thank you Chandeep for your outstanding way to explain the solutions.

I will add this to my favorites. I have seen many techniques to combine inconsistent column names. I like this one. The list accumulate method I do not understand or at least can't remember each time I need it. But this method is memorable.

Excellent video. I don’t think I could manage to replicate this but I found it a useful example of using PQ for wrangling data.

Loved it ! A very smart solution to a very common issue.

Excellent video Chandeep! Thank you very much!

Woow. You coverd every thing 😊 by easiest way

Excellent presentation. Thanks

Been looking for this recently! Saved my life! 🎉

This video is super helpful as are all the videos. I've learned so much from this channel. Question I have, in this video you create a custom column to create a table so we can see all the sheets within a file. Is it possible to filter to a particular sheet at this step BEFORE expanding the custom column? I have multiple excel files and each has mutliple sheets. One sheet on each file is over 600,000 rows, and I'd like to avoid loading that sheet when i click expand.Is this possible to do?

Very impressive. YOu have an incredibly deep understanding of the data structure

Excellent video. Thank you m8.

Hi, thanks for your video, I was wondering if this method could be applied to combine csv files instead excel files.

Your vedios r very very good I basic learner will watch all one by one

Your videos are brilliant and you're so inspirational. You make it easy to understand the logic and then the code to apply the logic. This video has really helped me and I'd like to say a big THANK YOU !

Good lesson!

Omgggggggg you just saved my life. Thank you SO much ❤❤❤

I have applied the learning from this video to the task that I need completing and it works a treat, thank you Chandeep. One quick question. I have no problem doing this when I use Power Query in Excel. How do I do the same when I use Power Query from within Power BI please? Specifically, how do I load the "mapping" list from Power BI into Excel, so I can generate the "rename" column before loading the table back from Excel into Power BI to generate the "Renames" query? Thanks

Amazing Work.

Thanks a lot ! It’s very helpful ❤

Very helpful video. Simple solution for a very common issue. Thank you very much for your effort to teach us.

Good solution, I like it What I can point out as improvement is the stability issue that you pointed out at 16:47 Indeed, you need to redo all of that because the table will store records which are not absolute, but some kind of position oriented based on content of the query behind it. I would say this is generally not a good practice to combine query generated table and manual input. Imagine you have multiple tables like that - it is extremely hard to control and spot the difference between them as at least they would be of the same color. My solution to such stability issues: 1. load the query table, but remain it intact - do not add anything to it manually 2. create another table manually and use different color theme (blue for example) so it is different from the query format 3. name this table and its columns absolutely same way and copy the query table content to your manual table - at this point you will have two tables which will be identical for its content 4. create data validation in manual table columns referring to the query table columns as a dynamic range using =INDIRECT("Table1[Column1]") string - you need to do it column by column 5. extend the manual table with new columns that you need - "rename" column in your example 6. add the controls through LEFT and RIGHT OUTER joins between the original query table and manual blue table to check the consistency - i.e., that you did not forget to include all of the entries to your manual table. Outcome of joins can be count or non-blank count that produces outcome of a check table with a single cell 7. merge the manual table with other query tables inside the query editor to achieve your goal Yes, it is much more than shown but it gives your control and automated ways to check the correctness of a process That's critical for a repeated exercise Thanks again!

Thank you, I really needed this solution! :)

Thank you for another great view. i am struggling to keep source file name in the final output. is that possible to do ...could you please help

A godly solution to a problem i have been facing for so long....Super.

i have watched alot videos and you are the best

This is really good .. got lot to learn

Hi there, thank you for this! What if the Excel sheets/files have different numbers of columns, which of course will have names not common to the other data sources/files?

Very well explianed.

Great solution Chandeep 👌 Could you please show solution for xls (not xlsx) files ? Looking for ways to automated conversion to xlsx or way to combine and use xls :)

Simply Gold Content as always.

Very good content and very useful.Thank very much

Really the videos that you post would be very helpful to those who works in the corporate world especially who into data and makes their job much easier. Thanks for your efforts and wish your dreams come true and achieve heights.

Life Saver Video!

thanks tutorial and simple file to step by step thank you very much

I am a very big fan of this channel. Your teaching skill very good that even newbies can easily understand. Thank you very much for this trick.

Superb ! Keep it up !

Many thanks Chandeep, For mapping list of lists: It will be better to use Table.ToRows only Instead of table.Transpose + Table.ToColumns Regards Mohammed from Algeria.

Thank you so much, this was very helpful

Another great video. We have all faced this issue sometime in our data combine journey. Thanks for laying it out so clearly. I would like to request you to create a video on setting up incremental refresh for files in sharepoint folder in Power BI. I have seen some solutions online but have never been able to get them to work. Thanks again!

Brilliant stuff- the best M channel 👌

one of the best tutorial keep on sharing

Wow that was hard work!! I used this on a folder full of csv files!! I followed you step by step and....it worked...OMG How do you know this stuff!! i would have never figured this out! thantks

wow, generating a list of all distinct column names for mapping is really genius. I also noticed that you faced the same problem of power query inserting rows in partial columns when query is refreshed which messes up the table. I got around this problem by using only VBA to refresh and disabling Explicit refresh. I don't think Microsoft is ever going to fix that.

this is amazing.. Thank You!

One of the best explanations

Thanks a lot! Very well understandable :)

Really well explanation.. Just subscribed...

Great video! You save my day with this awesome tutorial 😁😁

It is so clever to transpose and convert to list of lists! :)

Another awesome lesson! Thanks for providing the sample files too. Thumbs up!!

Very good, it’s a tricky method! I try it with csv files and it failed because of the excel workbook function. I’ll look for on my own but maybe you’ve already solved this problem. Thanks

Amazing and very useful video. Thnx sir

very useful thanks!

This is super and is of big help!! Thank you!! Just wanted to know can we add the files names column at the end as sometimes we have to collate the data of different region, months, companies which will be very difficult to segregate without classifying.

Excellent solution to a recurring problem. Greetings from Chile

Sir, how to learn all these codes/ syntaxes, video and explanation is awesome. Could you please suggest book or any material for this ?

Nice , I m being a regular viewer of your channel. keep the good work.

This video is gold. ❤

Good video If header names of columns are in random order, does it reorder automatically?

Thank you Chandeep for this lovely video. Is there a way you can share a link to the video (if you have made) where we do merge different tables from sharepoint with different headers.

Sir, I posted this question previously too. How to deal with filter function applied cells to form a table and sorting values using Power query. Another question is about using using sort function alone for two adjacent columns with filter function applied cells...

excellently executed (MASTER)

As usual great 👍

Thanks a lot, the video helped

awesome, thanks for sharing

Million Thanks

Brilliant!!!

Excellent. Very useful

Thanks for the video!. May I know the name of the mic you use to record the videos?

That was a lovely solution - do you have a feel for performance at scale (say 500k rows +)

Well done as usually!!! Can we except M language course???

Good stuff! You don’t have to transpose the table if Table.ToRows is used instead of Table.ToColumns.

Very good and very useful trick Chandeep! Thank you very much. I found that if we hardcode the rename values in a custom column with "ifs" and "List.AnyTrue", we can skip the manual rename each time the sources change. Even better, we can create a function for renaming, and use it and update it as needed 🤷‍♂️ The thing is, the rename with 6-10 columns is very easy, but 30 and more.. uff 😥

Excellent content 😊

Amazing 😍

Its Just Awesome…. Is it possible in Excel 2016 version??

amazing, thanks for detailed explanation, very easy to understand each step. Can you guide when new excel is added to source folder? How can those data automatically get loaded to Combined File?

Hi can you give some ideas regarding revenue split related. I have a sales amount in 3 columns depending on how many sales people share the single invoice amount along with that sales representative has a target in the target table. I have to show sales representative sales vs target

Very Nice Video Bro, Can you please make videos on functions..

hello, I have excel files with secondary sheets containing notes (not needed in the actual data table). @ around 4:30, is there a way to exclude these sheets from the list? Also, would like to learn how to Add a column for each table indicating the source file, so i can put a slicer on the visualization. thank you so much!

Thanks for sharing ❤

can you explain the step how you open your column headers from PowerBI in Excel? Dont find an option that I can execute the Data-> From TableRange (on min. 9:04) that its loading the data into the same PowerBI instance. thank you and its a great video
