Get Data from Folder with Today's Date

Hi all,

 

I need PowerQuery to go every time and  search for a file that is stored in a folder with today's date.

 

Explanation:

 

Our raw data (the one we feed to PowerQuery) are stored to our local shared drive; this is an example of the path:

 

REPORTS [FOLDER]

----------30102019 [FOLDER]

               file1.csv

----------31102019 [FOLDER]

               file1.csv

 

As you can see,  every day the new report is stored in a folder with the same date of when the report is extracted.

 

  • The filename never changes.
  •  
  • The timestamp on the folder is when the folder itself was created.

 

How can I tell PowerQuery to go and look for the latest folder and pickup file1.csv?

    Hi luke_avalle, 

    You could try below M code to see whether it work or not

    let
    Source = Folder.Files("C:\Users\(username)\Documents\New folder"),
    #"Filtered Rows" = Table.SelectRows(Source, each ([Folder Path] = "C:\Users\zoezhi\Documents\New folder\"&Date.ToText(DateTime.Date(DateTime.LocalNow()),"yyyyMMdd")&"\"))
in
    #"Filtered Rows"

     

    Best Regards,

    Anonymous I had something similar that I had to work with.  The solution I found was by using a the 

    DateTime.LocalNow()

     function in Power Query. You can then extract the day, month, and year and create a string to match the format that you use in your file structure. To manipulate the date, you can use 

    DateTime.ToText()

     function to format the date as you wish.

     

    Hope that helps!

    Hi all, 

    Just to add an extra bit of complexity onto this - how would I allow other users to refresh this power query?.

     

    Let's say I have a sharepoint with the excel file in. Is it possible for others who have access to this sharepoint to go in and refresh this query so it pulls the most recent data, without them having to setup a new data source connection each time?
