(M code)How to extract multiple sheet data from Excel which in multiple folder by Power Query(noDAX)

[QZ]

The budget Excel file save in folder every month, the folder name named by year and month, for example: 202401, 202402, ......,
(refer bellow picture, for the purpose of simplification, only save the excel file in 202401 and 202405 folder)

In the Excel file, each department has each sheet, for example: HR, IT, ......, 

The budget amount be allocated by quarter, for example, Q1, Q2, Q3, Q4,

The budget be divided into category and sub category, for example: category: Fixed costs; sub category: variable costs, labor costs, fixed costs(except labor costs),

My purpose is extracting all sheets data in excels which under D:\DeptBudget folder by Power Query(not DAX), final get table data(pls refer bellow picture which in green rectangular frame), it would by much appreciated if anyone afford the accomplishing method.

* Refer bellow video: Combine Excel Worksheet Data , I can extract the raw data which under D:\DeptBudget folder excel files(just like get data from folder in Power BI Desktop), but that's not what I want. I can process the budget amount by catetory and sub category for individual department sheet, but have no idea to multiple department sheets.

refer bellow pic, cell value is a table, can change value from red rectangular frame to green rectangular frame directly by Power Query?

Hi @QZ ,
Based on your description, you can try to perform the following steps:
First, choose get data from folder

Then,choose the target folder and open and choose the combine and transfrom data

Click ok

Open the advanced editor and paste the Mcode

let
    Source = Folder.Files("C:\Users\yourcomputername\Desktop\DeptBudget"),
    #"Removed Other Columns" = Table.SelectColumns(Source,{"Content", "Name"}),
    #"Added Custom" = Table.AddColumn(#"Removed Other Columns", "Custom", each Excel.Workbook([Content])),
    #"Expanded Custom" = Table.ExpandTableColumn(#"Added Custom", "Custom", {"Name", "Data", "Item", "Kind", "Hidden"}, {"Custom.Name", "Custom.Data", "Custom.Item", "Custom.Kind", "Custom.Hidden"}),
    #"Removed Other Columns1" = Table.SelectColumns(#"Expanded Custom",{"Custom.Name", "Custom.Data"}),
    #"Expanded Custom.Data" = Table.ExpandTableColumn(#"Removed Other Columns1", "Custom.Data", {"Column1", "Column2", "Column3", "Column4", "Column5", "Column6"}, {"Custom.Data.Column1", "Custom.Data.Column2", "Custom.Data.Column3", "Custom.Data.Column4", "Custom.Data.Column5", "Custom.Data.Column6"})
in
    #"Expanded Custom.Data"

Final output

Note that you can format all the data before merging it, so that you can get the data into the desired format faster.
