![string](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/0/4/044bef7f7f9ab5d9994582de3fe48b4ba22956a9.png) sorry for my poor english I tried to create the sheets, and make a string for name them. But I want to indicate numbers like 001, 002, 078…not only true value. Is it possible to make numbers or string with a specific node? or I just have to filter the list and put zero at each group of ciphers? ---

Hi @syhyunXJ784, Welcome to the Dynamo community. You can use the String.PadLeft node to get the desired result. ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/3/5/356b61389f387e704b40627d92d15e7ecc5c7843.png) ---
