Prerequisites: Local filesystem paths readable by Studio or runtime agent. See also File Drop Automation for folder-watch triggers.
Build a file processing workflow from template #3: read a JSON file, transform it, and write the result to another path.
What this template does
- Read Input —
/data/input.json. - Transform — map or reshape payload.
- Write Output —
/data/output.json.
Step 1 — Load the template
- Studio → Templates → search
File Transform Pipeline. - Load template #3.
Step 2 — Paths
- Update input and output paths for your host (Windows or Linux).
- Use
{{$var.dataDir}}for portable paths across environments.
Step 3 — Transform
- Edit the transform expression to rename fields, filter arrays, or template output.
- Run Dry Run with inline test JSON.
Step 4 — Automate
Add File Changed trigger to run when new files land in an inbox folder — pairs naturally with File Drop Automation.
