Extract Alphanumeric Pattern from Text Field

[lchirag]

Hi There!

I have a column in the PBI dataset that is TEXT and has very long text data.

Every row of this field has an Alphanumeric string added in any part of the text. However, the pattern to be extracted is always starting with ABCD0123456. 

How do I search the entire text field and extract this patterned data?

Thank you in anticipation for helping me out!

Hi @lchirag 

You can give this custom lookupFunction a go:

let
    Source = "Purchase dept ID: PURT0001894 Software License Renewals Warehouse Area: Applications Hosting Team INITIATIVE/CATEGORY: MS Teams License renewal",
    lookupFunction = ( lookIn as text, alphaCount as number, numberCount as number ) as text =>
        [
            len = alphaCount + numberCount,
            items = List.Select( Text.Split(lookIn, " "), each Text.Length(_) = len),
            find = List.Select( items, each 
                [
                    split = Splitter.SplitTextByCharacterTransition({"A".."Z"}, {"0".."9"})(_),
                    test = Text.Length( split{0} ) = alphaCount and Text.Length( split{1} ) = numberCount
                ][test]
            ),
            combi = Text.Combine( find, ", ")
        ][combi],
    result = lookupFunction(Source, 4, 7)
in
    result

or maybe this

let
    Source = "Purchase dept ID: PURT0001894 Software License Renewals Warehouse Area: Applications Hosting Team INITIATIVE/CATEGORY: MS Teams License renewal",
    lookupFunction = (lookIn as text, alphaCount as number, numberCount as number) as text =>
        let
            patternLen = alphaCount + numberCount,
            isPatternMatch = (text) => 
                ( Text.Remove(Text.Start(text, alphaCount), {"A".."Z"}) = "" and
                  Text.Remove(Text.End(text, numberCount), {"0".."9"}) = "" ),
            items = List.Select(Text.Split(lookIn, " "), each Text.Length(_) = patternLen),
            matches = List.Select(items, each isPatternMatch(_))
        in  
            Text.Combine(matches, ", "),
    Result = lookupFunction(Source, 4, 7)
in
    Result

both return this result

I hope this is helplful
