This document summarizes various data weave operators for coercing data types and transforming data. It describes operators for coercing data to strings, numbers, and dates. It also covers the flatten and split by operators for transforming array and string data.

1. Data weave operators
Coerce to string
(':any', ':type') ⇒ ':string'
Any simple types can be coerced to string. If formatting is required
(such as for a number or date) the format schema property can be
used.
Date and number format schemas are based on Java
DateTimeFormatter and DecimalFormat.

3. Coerce to number
• (':string', ':type') ⇒ ':number'
• A string can be coerced to number. If the given
number has a specific format the schema
property can be used.
• Any format pattern accepted by
DecimalFormat is allowed.

6. Coerce a date to number
• (':time', ':type') ⇒ ':number'
• When coercing a date to a number, there is an
extra parameter you can add – 'unit' – to
specify what unit of time to use,

8. Coerce to date
• (':string', ':type')/(':number', ':type') ⇒ ':date'
• Date types can be coerced from string or
number.
• Any format pattern accepted by
DateTimeFormatter is allowed.

11. Flatten
•
(':array') ⇒ ':array'
If you have an array of arrays, this function can
flatten it into a single simple array.

14. Split By
• (':string', ':string')/(':string', ':regex') ⇒ ':array'
• Performs the opposite operation as Join By. It
splits a string into an array of separate
elements, looking for instances of the
provided string and using it as a separator.
