Detect number in a text string

[Anonymous]

I want a true/false statement in Power Query to detect numbers in a text string.

45a- TRUE

ab- FALSE

34- TRUE

aa46- TRUE

[VinceMaku]

Actually there is another solution if you want to make it dynamic you can use this kind of code
Let's say the name of this field is [Sample1]

45a- TRUE

ab- FALSE

34- TRUE

aa46- TRUE

Power Query code:
if List.AnyTrue(List.Transform({0..9},(NumberColumn) => Text.Contains([Sample1],Number.ToText(NumberColumn)))) = true then "TRUE" else "FALSE"

Please put thumbs up if I help you better

Hi @Anonymous ，

Text.contails could not work on more then one values, similar error refer:

https://community.powerbi.com/t5/Power-Query/using-if-text-Contains-for-multiple-conditions-in-Power-Query-M/td-p/2196090 

And change yours to the below:

if Text.Contains([Product], "1")  or Text.Contains([Product], "2")                   or Text.Contains([Product], "3")                   or Text.Contains([Product], "4")                   or Text.Contains([Product], "5")                   or Text.Contains([Product], "6")                   or Text.Contains([Product], "7")                   or Text.Contains([Product], "8")                   or Text.Contains([Product], "9")                   or Text.Contains([Product], "0")    then "True" else "False"

Did I answer your question? Mark my post as a solution!

Using the "Contains" option in the conditional column interface seems to work for me:

Hi  @PaulDBrown ,

Thank you for your reply, based on what you have provided, each time you use Contains, you also judge only one element and then use a combination of multiple judgments to get the final result.

Best Regards

See if this helps:

Thanks for the reply but I don't want to extract a number from the string. I want a function to only detects IF there is a number in the text string and give me a true/false value

[PaulDBrown]

Well... that link got me to this:

Using

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WSkw0NlGK1QEykszy8sCs3FwIlZdvCGYkJRlZghmWFklJSrGxAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [List = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"List", type text}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each Text.Select([List], {"0".."9"})),
    #"Changed Type1" = Table.TransformColumnTypes(#"Added Custom",{{"Custom", Int64.Type}}),
    #"Added Conditional Column" = Table.AddColumn(#"Changed Type1", "Custom.1", each if [Custom] = null then false else true),
    #"Removed Columns" = Table.RemoveColumns(#"Added Conditional Column",{"Custom"})
in
    #"Removed Columns"

Does that help?

I'm sorry but the code is just too complex for me to understand. I find it easier to add a condition with true conditions being every number from 1-9, see below:

However a single line code would be easier to manage. Somtehing like this: 

text.Contains([Product], type number)

[PaulDBrown]

Your conditional column approach does deliver a single line of code (and is way simpler than my suggestion! )

= Table.AddColumn(#"Renamed Columns", "Number?", each if Text.Contains([Product], "1") then true else if Text.Contains([Product], "2") then true else if Text.Contains([Product], "3") then true else if Text.Contains([Product], "4") then true else if Text.Contains([Product], "5") then true else if Text.Contains([Product], "6") then true else if Text.Contains([Product], "7") then true else if Text.Contains([Product], "8") then true else if Text.Contains([Product], "9") then true else if Text.Contains([Product], "0") then true else false)

However, I can't get the code to work properly, I keep getting an error

[PaulDBrown]

It shouldn't return an error. Is the Product column set as type Text?

[Anonymous]

Yes it's set as Text. I get an Expression. Error. Not possible to convert the type Type to type Text.

Information:
Value=[Type]
Type=[Type]
