Throughout the documentation we refer to data types that can be used in the expression parser and its functions and field codes.

Data types define what kind of data e.g. a function needs as an input and what you should expect as an output.

Data types overview

Data typeDescription

TEXT

This type represents any kind of text or character string including all kinds of select and multi-select fields

NUMBER

This type represents numeric values, and is also used to store date, time and date-time values. Learn more about Dates, times and time zones

LIST

  • Number list: This type represents a collection of numeric values returned by various functions. The size may vary from 0 to any number of numeric values.
  • Text list: This type represents a collection of text values returned by various functions. The size may vary from 0 to any number of text values.
  • Issue list: This type represents a collection of issues. The size may vary from 0 to any number of issues. It is returned by issue selection of filtering functions.

Learn more about Lists.

If you need to "flatten" the list, or simply convert it to a text, to be written into any field, comment, etc., make sure to have a look at the toString() function!

BOOLEAN

Some operators and workflow functions return a logical, or boolean, value of true or false. Apart from the conditional operator, this data type is typically used when writing expressions in the Logical mode.


Casting (converting) data types

Casting (or transforming) 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.
