What is the Template Editor?

The Template Editor is a Transloadit account interface for creating and modifying Templates. Its code editor authors Assembly Instructions, the declarative JSON that defines a file-processing workflow.

How the Template Editor works

The Transloadit Template Editor provides a managed place to author the Assembly Instructions JSON that defines an Assembly workflow. It can help with syntax and available operations, while the author still controls step names, dependencies, parameter types, and output flow. Editing is therefore both a configuration task and a change to an API-facing production dependency. Teams use the interface during workflow design and troubleshooting, then validate representative files before promoting a revision to callers.

Key facts

  1. Valid JSON proves only that the document parses; references can still point to the wrong step, parameters can be semantically invalid, and outputs can differ from what a caller expects.
  2. Testing should include each accepted input family and important failure path, because media-dependent branches may not execute when the editor is tried with only one representative file.
  3. Concurrent or undocumented edits can make rollback difficult, so exporting reviewed definitions or maintaining equivalent version history outside the interface improves traceability.

When the Template Editor matters

Use the editor to inspect and revise workflow steps while keeping the resulting JSON valid. A syntactically correct change can still alter step dependencies or outputs, so test revisions before production use.
