Replace or Remove first number using regrexchange

Hi guys, so i want to replace “0” and change to “63”. For example from the phone numbers 083210987733 and want to be 6383210987733. How can i change that in Knime?

Thank you

Hello @febriansyah28,

You can use the String Manipulation node and write an expression like:

regexReplace($column1$, “^0”, “63”)

for your reference. Also, an image is attached:
