Full definition of transform
Transforms are the glue between systems that don't speak the same data shape. Common transforms: parse JSON, split a string, format a date, compute a derived field. In Tiny Command, a Transformer step lets you write a JavaScript expression to reshape data between steps. Avoid putting business logic in transforms — keep them about data shape, not decisions.

FAQ
Common questions about transform
Transform or code step?
Transform for one-off field changes. Code step when you need conditional logic, loops, or to call external libraries.
What if my transform fails?
Tiny Command logs the failed step's input, output and error in the run history, so you can fix the expression and test the step again.
