Re: Split Value and String
Hi @Pabblo_96,
@ManishSolanki highlighted this post to me after I created a video to do something similar https://youtu.be/_6f5UBpHhZ0
In this video you will learn how to remove or keep characters, symbols or numbers in a string with 1 action. For example, using your requirement we can use one select to keep the integers and another select to keep the non integers and return both strings with a join expression.

Here is the flow in edit mode:

FROM of the select is:
chunk(outputs('Compose'),1) which turns your string into an array (as seen in the video)
Note that text mode is enabled on the select MAP.
to keep integers you can use if(isInt(item()),item(),'') which if isint is true, we output the integer, otherwise we output an empty string ''.
to keep the non integers (i.e. the characters) you can use if(isInt(item()),'',item()) which if isint is true, we output the an empty string '' otherwise we output the non integer value.
To get the string of both selects, you can use join(body('SelectIsInt'),'') or join(body('SelectString'),'')
My video above will explain this in more detail and hopefully open up more ideas for efficiency too.
Cheers
Damien
