“Dynamo Script to Automatically Renumber Text Notes Starting with Prefix (e.g., Z2_L0_) in Revit”

[Mike.Buttery]

Hi Tobiyay, welcome
What have you tried so far?

You can collect all the text notes in a document

There are string nodes that can find, extract and modify the data as required
You can save back to the notes

This would be an excellent first project for a new Dynamo user

Please take the time to read How to get help on the Dynamo forums
