Hi,
I’ve read that when combining identical files, it is recommended to do any transformation in the example file.
I’ve 3 files identical files as follows: CompanyA.xlsx (10.2 KB) CompanyB.xlsx (10.2 KB) CompanyC.xlsx (10.6 KB)
So, I go through the process for combine them all as follows:
So my question is why when I work with the sample file the other query screw and broke?
Shall I work only with the main generated query from the first place?
And if working with the main generated query is the way to go, then when is the case to only work with the sample file?
Thanks
First, using Excel.Workbook([Content]) we’re returning this table for each file
.
From that table we are keeping Rows that match this condition: [Kind] = “Table” and Text.StartsWith( [Name], “Company”)
From the remaining rows in the table we’re extracting a list with tables in the [Data] column
And finally we’re combining those tables with Table.Combine
.
I made a reference to this query and extracted the [Custom] column as a list, to combine them. Table.Combine( Sample[Custom] )
Much appreciated and thanks a lot.
Please, @Melissa … I can realize that I’m missing a solid foundation in Power Query.
So, please, if I want to get a solid foundation, what shall I do?
Thanks
@MGadAllah start by working through the Power Query related courses in the portal
I recommend this order:
Data Transformations And Modeling
Fundamentals In Power Query And M
Depending on if already available a new course on working with nested structured values OR the webinars: Nested Structured Values (Part 1) & Nested Structured Values (Part 2)
Applied Problem Solving with Power Query/M
Personally, I’ve learned the most by doing and experimenting. There are many #excelchallenge and/or #powerquerychallenge 's online and I can highly recommend to participate, explore solutions by others and ask queystions - there is a great community out there.
A final recommendation follow ExcelBI on LinkedIn, Vijay posts daily challenges for you to get stuck in. Best of luck with your learnings!
