How to remove numbers from a string?

[Aditya_Singh]

I want to remove all the numbers from a string. I tried using replace all text with segment block but I cannot define the segment and also the length of the string as it can be of any length.

For example:
25416898HelloWorld
1234HelloWorld
HelloWorld1234

The string length can be any. How do I remove all the numbers from the string leaving only letters in it?

This was my try without extension

Note that this cannot be considered as solution to anyone who is trying similar thing. This was just random try to see if it can be done without extension. I have just tested one case as shown above. I don’t know if all the blocks above are correct or not. Using the mentioned extension is still the appropriate way.
