Advice on loading data from multiple xlsx in different folders


I have a personal winter project to learn about how Power BI can improve my workflow.

Case is that I have a projects server volume with project reports as excel files. All the excel files are structured the same way but they reside in project folders. We have the folder structured as

p://area/year/project number/discipline/sustainability/...and here I have the two excel files...


One way that requires programmig that I'm not capable of is to automate BI to run though the whole folder structure and load everything under each and every "sustainability" folder. We have about 300 project each year and I assume this would be time consuming even if I got it to work.


Another way is to export to excel files into one single dedicated folder instead. This folder would then contain hundreds of excel files but it would be easy to automate the data import.


Your two cents? I lean towards the second way with one folder...

@maknu , My advice would be to put them in a single folder. if possible on the SharePoint folder.  That will keep it easy and clean

Hi  @maknu ,


Here's a blog about this, please refer to

Power Query dynamic file path | Excel Quick Help

Overview of steps

  1. Enter file path and file names into cells in a separate worksheet in the Excel workbook;
  2. Name the cells (click in the cell, and add a cell label into the name box);
  3. Create custom objects at the start of the Power Query which define the file paths using the named cell references, using the Advanced Editor;
  4. Update the file path and file name details in the named cells to refresh the Power Query data source.





Best Regards,

Stephen Tao
