Excel Power Query Download Did Not Complete
Remedios Fava
A lot of transformation steps available in power query will have various user input parameters and other setting associated with them. If you apply a filter on the product column to show all items not starting with Pen, you might later decide you need to change this filter step to show all items not equal to Pen. You can make these edits from the Applied Step area.
Can I link a power query to a regular worksheet. When I link to a regular worksheet and refresh the power query the link formula changes, drops down row numbers. I googled this and have not found the answer. Is this possible?

Hi Chandoo,
thank you very much for this easy-to-understand tutorial.
I only face one problem: when I select a folder via data/new query/from file/from folder the navigator window does not open but I am led directly to power query with no possibilities to click combine, transform or load.
When using the other data sources (from workbook etc) everything works well. Do you or anybody else have an idea to fix this problem?
Best regards
Thank you for this tutorial.
Could you kindly answer my query.. After transforming data in the first example, I have Close and Apply (not Close and Load) and hence do not have an excel popping up. Please advise.
Let me come straight to the point, Power Query is one of the advanced Excel skills that you need to learn and in this tutorial, you will be exploring power query in detail and will be learning to transform data with it.
After getting data in the power query you have a whole bunch of options that you can use to transform it and clean it. It creates queries for all the steps you perform (in a sequence one step after another).
At the top of each column, you can see the data type of the data in the column. When you load data into the editor the power query applies the right data type (almost every time) to each column automatically.
And on the left side of the column header there you have the filter button which you can use to filter values from the column. Note: When you filter values from a column, the power query takes it as one step and lists it in the applied steps.
The best part of the power query is you have the option to get data from multiple sources and transform that data and then load it into the worksheet. When you click on the Get Data in the GET & TRANSFORM you can see the complete list of data sources that you can get data load into the editor.
You have a list of values, and you want to replace a value or some values with something else. Well, with the help of the power query you can create a query and replaces those values, in no time.
So you have a list of values and from this list, you want to add a Prefix/Suffix in each cell. In Excel, you can use the concatenate method but in power query, there is a simple to use option for both.
Why is this a good thing? Consider the questions that were asked at the beginning of this section. Since no data is imported to the Power BI Desktop, that means it is less important how powerful your personal laptop is because all query results are now processed on the source server instead of your laptop. It also means that there is no need to refresh the results in Power BI because any reports you design are always pointing to a live version of the data source. That's a huge benefit!
Hi Svetlana
Thanks for this great post. I have 3 worksheets (Tables) that I want to join in one worksheet (Table). I tried it as you described using power query, but at final step I get following error:
"Initialization of the data source failed.
Check the database server or contact your database administrator. Make sure the external database is available, and then try the operation again. If you see this message again, create a new data source to connect to the database."
