Expression to keep leading zero in a number
I am using Mapper snap to map an integer column from database to CSV file. How do you write expression for this field “MyNum” to keep the leading zero in the csv file? like 04567
Thanks

Hi @mtran21
What is the desired length with leading zeroes? you could have examples like 00123, 01234, or 00001.
Under the assumption that you know the length, for example 5 here, then you could do something like:
("00000"+$MyNum.toString()).slice(-5)
and you’ll always be having leading zeros and lengths == 5.

Thank you. This worked good
