How to get data from the lastest file?

Hi all,

I need to get the data from a file with the latest issue number. I can get a list of the files from the week and extract the issue number from it, but then how to I filter this out to get the highest issue number?

In the above example I want to get only file issue 7 imported into my query, so I will need to filter for 7 in this example. But when issue 8 comes out, it needs to pickup the data from issue 8.

Hi @Oliehoek ,

 

How about this? 🙂

 

Before:

After:

Here the code in Power Query M that you can paste into the advanced editor (if you do not know, how to exactly do this, please check out this quick walkthrough)

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlSK1YlWMgKTxmDSBEyagkkzMGkOJi2UYmMB", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [YourColumn = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"YourColumn", Int64.Type}}),
    #"Filtered Rows" = Table.SelectRows(#"Changed Type", each ([YourColumn] = List.Max(#"Changed Type"[YourColumn])))
in
    #"Filtered Rows"

 

The idea is to filter your column with the maximum of that exact column. Note "Changed Type" needs to be substituted with the previous step in your query.

 

Let me know if this helps 🙂
