How to remove characters from a string ?
You have a list of strings like:
{"ABHello", "ABAppian", "ABWorld"}
Each value starts with "AB", and the goal is to remove this prefix from every string.

Answer
We can achieve this using a!forEach() along with the mid() and len() functions.
a!localVariables(
local!array: {"ABHello", "ABAppian", "ABWorld"},
a!forEach(
items: local!array,
expression: mid(fv!item, 3, len(fv!item)-2)
)
)
Explanation
- a!forEach() iterates through each item in the list
- fv!item represents the current string
- mid() extracts a substring:
- Starts at position 3 (skipping "AB")
- Extracts the remaining characters dynamically using len()
This ensures that no matter the length of the string, the first two characters are always removed.
