When to use Mapper

Choose Mapper when:

  • a source file uses values that need to be converted before use elsewhere
  • the same concept is represented differently across systems
  • you need consistent output values for reporting or integration

Good fits​

Mapper is a strong fit for repeatable business rules that should be applied the same way each time similar data arrives.

Start small first​

For a first Run, test the workflow with a small sample File. This helps confirm that the result matches the intended business outcome before you scale up.

When to use a different Tool​

When you are only cleaning whitespace or capitalization, Cleaner may be enough.

You can also use Choose the right Tool if you are deciding between Tools.
