In this blog post, we will explore how to generate random IDs using Apps Script. We will write a function that creates a random ID of a specified length using a character pool. This can be useful for generating unique identifiers for various purposes.


Code Explanation

The code defines a function getRandomId that generates a random ID. It uses a constant idLength to specify the length of the ID, and a constant charPool to define the characters that can be used in the ID.

A variable randomId is initialized as an empty string. The function then loops idLength times, each time appending a random character from the charPool using the charAt method.

Finally, the generated ID is returned.

AI Prompt

Write a function that generates a random ID of a specified length using a character pool. Log the generated ID. The function should take the ID length and the character pool as parameters.
