Speed-up a query to retrieve Excel tables from sharepoint

[PabloML]

Dear all,

I have a query that the latest step takes about 6/7 min. to load. I was wonder if I could do it differently and speed-up the process:

let

    Source = SharePoint.Files("sharepoint....", [ApiVersion = 15]),

    OnlyXLSXFiles = Table.SelectRows(Source, each ([Extension] = ".xlsx")),

    WorkbooksContent = Table.TransformColumns (OnlyXLSXFiles, {"Content", each Table.SelectRows(Excel.Workbook(_) , each [Kind] = "Table" )})

In

WorkbooksContent

Thanks.

If various sheets are not essential then you can try saving the file as a .csv - those are faster typically than Excel files.
