Load data files from folder and Power Query to load each excel sheet from each excel file

Hi All,

 

I have data source which is from folder, I choose the directory and I combine and transform data (at this stage, i can only choose 1 sheet)

 

Different excel sometimes have 2 excel sheets and 3 excel sheets. but the sheet names are consistent

you can load all the file by the below code (with comments for each step)

 

let
    // Set the folder path
    FolderPath = "C:\YourFolderPath\",

    // Load all files from the folder
    Source = Folder.Files(FolderPath),

    // Filter to only include Excel files
    ExcelFiles = Table.SelectRows(Source, each Text.EndsWith([Name], ".xlsx") or Text.EndsWith([Name], ".xls")),

    // Add a column to extract data from each file
    AddCustom = Table.AddColumn(ExcelFiles, "Data", each Excel.Workbook([Content], true)),

    // Expand the Data column to get each sheet from each file
    ExpandSheets = Table.ExpandTableColumn(AddCustom, "Data", {"Name", "Data"}, {"SheetName", "Data"}),

    // If you want to filter by specific sheet names, uncomment and modify this line:
    // FilterSheets = Table.SelectRows(ExpandSheets, each [SheetName] = "Sheet1" or [SheetName] = "Sheet2"),

    // Expand the data in each sheet
    ExpandData = Table.ExpandTableColumn(ExpandSheets, "Data", Table.ColumnNames(ExpandSheets[Data]{0})),

    // Optional: Add a column to identify the source file name
    AddSourceInfo = Table.AddColumn(ExpandData, "SourceFile", each [Name])
in
    AddSourceInfo

Go to the power query, then in the Home tab, pick Advance EDitor, in the oppened window, remove all the command and past the code I have provided.

C:\YourFolderPath\

as folder path, replace it by your own folder path
