Extract number from string

[Marini83]

Say I have a string P001 in a Context variable, how can I get the number 001 and assign it back to that context variable?

Hi @Marini83 

Just to clarify, will your input value always be in the format - 1 alpha character followed by 3 numbers? Or will the preceding number of characters before the number variable?

Hi,

If the syntax is always PXXX, you can do like that :

Set(VAR, Value(Right(YourString,3)))

Presumably yes , It should be in that format.

@Marini83,

Then you can process as I explained, and put the code in the OnSelect property of a Button, for example.

Hi @Marini83 ,

Do you want to extract the Number value from a Text string?

Based on the needs that you mentioned, I think the Substitute function could achieve your needs. I have made a test on my side, please take a try with the following workaround:

Set the OnSelect property of the "Initialize" button to following:

UpdateContext({ContextVar1: "P001"})

Set the OnSelect proeprty of the "Extract Number" button to following:

UpdateContext({ContextVar1: Substitute(ContextVar1, "P","")})    /* <-- On your side, you should take a try with this formula to achieve your needs */

Set the Text property of the Label to following:

"Current Context Variable value: " & ContextVar1

Please check the following GIF screenshot for more details:

Assuming that the context variable is set to value as:

UpdateContext({VariableName:"P001"});

Can you try to use below expression to get only the number after the first Character? This first character could be anything, not just "P".

UpdateContext({VariableName: Mid(VariableName,2)})

Hope this Helps!
