generating a defined number of IDs


Dear Smartsheet community,

I am trying to write a formula to generate a defined number of IDs.

In the screenshot below, if I enter 6 into the blue squared cell, I would like that 6 IDs are generated with a number incrementing at the end (ID_1, ..., ID_6).

if I enter 3, 3 labels are generated. (ID_1, ID_2, ID_3).

How could I proceed to generate these IDs based on a desired number ?

Thanks for your support!

    What's the max number of these that you might want to create?

    There are a number of ways to do this.

    Create columns:

    Running: Create a list of numbers, 1-whatever your max is. I do this by putting 1 in row 1, 2 in row 2, and then grabbing both cells and dragging down to auto increment. You can also put 1 in the first row, and then =Running1 + 1 in row 2, and dragging row 2 down

    Placeholder: Put =Num$1 in row 1 and drag it down

    Num: This is where you put your 6

    ID: Create a column formula: =IF(Running@row <= Placeholder@row, "ID_" + IF(Running@row <= Placeholder@row, Running@row))

    You could also use a Sheet Summary field, and eliminate the Placeholder and Num fields:

    =IF(Running@row <= Num#, "ID_" + IF(Running@row <= Num#, Running@row))

    The number will depend on the experiment but currently the max number will be 6 but could be less. We would like to get something dynamic, that can adapt to each experiment.
