Learn Power Query & Automate Boring Data Tasks in 15 Minutes!

[@vijayarjunwadkar]

Agree with you Chandoo. As data is growing and becoming complex, it will carry some legacy issues and new ones too, so ability to curate and clean it, is going to matter. Thank you for a simple yet powerful tutorial!

[@chandoo_]

You are welcome Vijay.

[@MelanieOnDemand]

Before removing duplicates, it is best to handle the letter cases first. Power Query treats lower case and upper case of the same letter as different characters. I would transform all email addresses to lower case before removing duplicates 😉. Great video, Chandoo!!

[@chandoo_]

Amazing tips @Melanieondemand Donut for you. 🍩

[@florisvanderleest7798]

With removing duplicates, one could also remove partial payments, in case the administrators entering new students don’t pay attention to duplicates or made typos

[@Nic-xr1og]

Great tip - thank you!!

[@ggggl8]

Just one Question: What if a student has paid 100 and next time 200, but both these entries are recorded separately so while removing duplicates his 1 entry will be deleted. So how can we counter that?

Chandoo - Your Excel tutorials are well above par and I have learned so much watching your videos. I've been able to impress myself and my colleagues with your tips and tricks. I'm not a data analyst - but data defines my actions and you have introduced me to so many functions and tips that make a HUGE difference in time and pinpointing issues. Very awesome and very well done in every respect. Thank you, you are appreciated.

Such a versatile tool, I discovered power query by accident years ago and have found new uses for it nearly every month since.

You can also create a folder that will automatically format itself if you have other raw data, say a different school but need the same analysis so you can drop the file into the power query folder and it will format everything so you don't have to repeat the steps

[@malwalsabino519]

Thanks Chandoo! I share with you the passion for Excel and particularly power query. My data cleaning skills started with copy and pass ( like your shorts " Isaw my boss doing this"), then, I discovered Excel formulas and functions and worked with the basics ilke right, left and mid for text then nested formulas/functions combining them with len, substitute etc for more efficient data cleaning and transformation but was sort of manual too. The game change emerged when I discovered power query, and since that time, things changed significantly. Now, I fear no more data consolidation, cleaning, and transformation with full automation. Because of the power query, I still stick to Excel as my first data analytics option. Thanks for the great content... I hope you would consider more content on another Excel power.. The power pivot Stay blessed

[@normanknutsen8253]

It is a fantastic tool have been using it for almost two years now and it has made things possible that I would have had to use Access for instead. The file combining feature is, I think the easiest way to combine similar files from a single file folder. Way back when I did the same thing for Access I had to use a good bit of VBA code to do the same thing that Power Query did in less than 10 clicks of the mouse. Love your videos Sir, keep up the good work

[@jasonmurray8777]

I use a lot of Power Query because I make a lot of Power BI dashboards. I spend a lot of time building star schemas - sometimes normalizing, sometimes not - it all depends on what I am trying to do with the data. The point is that I consider it to much more important to model the data for utility than the time I spend on any DAX I might write later. Honestly, its like 80% data modeling and 20% adding visualizations and some measures of calculated tables with DAX later. That said, I recently started going back to pre-formatting more significant transformations in SQL Server rather than trying to clean it up in Power Query. Loading some data into a data mart first to transform it with SQL, and then creating a view I can pull from into Power BI, is often a game changer for not having to do so many transforms in Power BI with Power Query. Put SQL and Power Query altogether and you can provide some very fast loading and amazing data visualization and reports with the Power BI report app too (you know - SSRS 2.0 for the cloud).

[@abbylynn8872]

Thank you for this. This completely resonated with me. 💕

[@saurabhdwivedi5866]

Hi @Jason Murray can you please elaborate it a bit so that a new data student like me will have good insight about the process you have mentioned.

[@jasonmurray8777]

@@saurabhdwivedi5866 Creating a good data model, most typically a star schema with a central fact table (or tables) surrounded by dimension tables (the things you will use as filters or slicers) is far more important than what you will do with DAX later. You need to understand the implications of any data model you create because if you don't you will often find yourself going back to the data model and possibly starting from scratch because you have painted yourself into a corner and no amount of DAX will get you out of it. That said, the model you choose will be affected by what existing relationships and cardinality exist within your data as well as your requirements for grain (granularity/precision) and, when very large data sets are involved, balancing those grain requirements against speed requirements. That said, my advice in this respect is, unless you have data that has already been modeled and has a data dictionary (or you are only working a single table or two), then you need to spend some time profiling your data when you start and make an entity relationship diagram (ERD). That ERD will most likely highlight for you what you can and can't do with your data and often leads you to realize what other data you need, but might not have, in order to meet requirements in the ultimate dashboard. With respect to my comment about using SQL first. You will likely often use data from a SQL database using an ODBC connection to pull it into Power BI. A database is typically a lot faster than Power BI and having pre-modeled data coming over from the SQL side will save you a lot of modeling on the Power BI side. Typically what you would do is create a view (or views) on the database side that have your data already as close to perfect as possible so you don't have to spend time cleaning it up in Power BI. Next, you would have a parameterized stored procedure to call against that view, even if the parameter was as broad as * (select everything). Accounts calling against the view would be in a role in the database that has minimum permissions to call those stored procedures against a schema that contains views for BI purposes (things like power BI) and that role would not have permissions to do anything else. This will help protect the data in your DB by not exposing the base table names, prevent SQL injection vulnerabilities, and make your data updates into Power BI that much faster. If you are savvy , you could also design a stored procedure in a way that only returns incremental updates for faster data loads without having to do the complex setup for incremental data on the Power Bi side. Anyhow, that is probably a lot more detail and probably leads you to many more questions. I suggest reading up on star models, ERDs, normalization, cardinality, and grain as well as the use of views with carefully permissioned stored procedures (in their own schema so you can manage the security at that level rather than by individual views) to provide efficient and secure return of data from a DB into Power BI rather than just doing everything inefficiently on the power bi side or making up for data model deficiencies with DAX wizardry later.

Power query's very useful as the intermediate step in between data e datavis, if you don't know good sql, your (power) querys, so as yours BIs, will be as performatic as a potato, when you're working with big datasets. Also, everything power query can do, dax can do better and more performatic, obviously once you load your raw, but clean, data with power query. As for me i'll confess once i started use sql and dax, power query only serves for me to load the data when not using direct query.

Tip: Disable the background refresh on the query. I noticed my pivot tables were still showing old data after hitting "refresh all." Disabling background refresh on the query will force the pivot tables to wait for the query to complete before they refresh and you will no longer have to refresh to pivot tables separately.
