Hi @Olivier Travers ,


I had the same use case.  My workaround was:

  1. Query 1 - load the document library data as a SharePoint List into a table. 
  2. Query 2 use SharePoint.Files to load in the file data. 
  3. In Query 2 merge in Query 1 using an inner join matched on the filename
  4. Expand out the metadata columns I needed from the library data table
  5. Remove all columns other than the required metadata and Content
  6. Fileted hidden files
  7. Extract table from content
  8. Expand table
  9. Remove content column
  10. Other data processing as required

This gave me exactly what I needed.  Hopefully it will help you too.
