How do i extract date from the source name which has string using power query

[ahamedafridi18]

i have exported csv dat which has got date in their source name. it is a daily download report. i want to create a custom column which extracts the date from the source name so that i can cretae the date column for the dataset.

An alternative way in PQ is to use this in a custom column

Text.BetweenDelimiters([Source.Name]," ",".",{0,1})

Hi @ahamedafridi18,

Here is a Dax query for a calculated column 'Date' to extract the date from the SourceName column and convert into date format

Date = FORMAT(DATEVALUE(RIGHT(LEFT([Source.Name],18),10)),"DD-MM-YYYY")

If you like my solution please consider giving a upvote..

Thank you!

Hi @ahamedafridi18,

There are so many different ways to achieve that, just wondering how representative the image is...
For example any of these will do, just insert a Custom Column and copy an expression from below, replace "Source" with the column reference [Source.Name]

let
    Source = "Detroit 21-02-2024.xlsx",
    AlwaysBetween = Text.BetweenDelimiters(Source, " ", "."),
    AtTheEnd = List.Reverse( Text.SplitAny( Source, " .") ){1}?,
    Anywhere = List.First( List.Select( Text.SplitAny( Source, " ."), each Text.Length( Text.Select(_, {"-"}) )=2 ))
in
    Anywhere

 I hope this is helpful
