- a branch-scoped Python script in the Transform panel
- a separate Filter node for simple keep-or-drop rules
What is live today
- branch labels in the Transform panel
- source table or resource selection from inside that panel
- a Python editor that expects
def transform(record): - a Load Example menu when example packs exist for the current source type
- Preview with sample data before saving
- a dedicated Save Script action
- a Filter node with Python Expression and SQL WHERE tabs
What is not the supported workflow
- a point-and-click rename screen
- a separate cast wizard
- a visual fill-nulls screen
- standalone visual-mapping documentation as the primary production path
- a separate transform administration workflow
- a user-facing toggle for skipping transform errors; saved scripts currently use fail-on-error behavior
Fast path
- Select the source table or resource.
- Keep the default pass-through script first.
- Preview the current payload.
- Add one transformation step.
- Preview again.
- Save the script.
- Validate the destination preview and then run manually.
