Converting (or casting) data types is very important throughout all functions provided by JWT.

To be able to set, transform or calculate values it might be necessary to turn a text value to a number, a number or a timestamp to a text, and even individual text or number values to a list.

The following functions will help you to achieve that.

Available functions

Whenever you write a numeric term at the right-hand side of the + operator or a comparison operator like = , and the left-hand side is occupied by a text term, JWT will automatically transform the right-hand side term into a text toString().


"His age is " + 30 is equivalent to "His age is " + toString(30)

= (any comparison operator)

"30" = 30 is equivalent to "30" = toString(30)
