Transform Data Without the Lag

Manually building custom data mappings is time-consuming and technical. Chain.io’s Custom Mapping Tool streamlines the process, letting your team create, test, and deploy complex data transformations, all within the Chain.io platform. No external tools required.

You can build mappings for EDI, JSON, CSV, and XML files to modernize your data conversion process. Get granular with JSONata logic to tailor and enhance your custom mappings.

It’s enterprise grade self-service.

A Visual Editor Built for Logistics

Inside your Chain.io Workspace, navigate to the Developer Center to access the Custom Mapping Tool. From there, you can create, edit, and manage data mappings with a simple, three-panel editor:

  • Left Panel: Your source data
  • Middle Panel: Your JSONata transformation logic
  • Right Panel: Real-time output preview

As you construct your mapping, your output updates in real-time, so you know instantly if your transformation is working. Let the Custom Mapping Tool do the heavy lifting.

Flexible Format Control

The Custom Mapping Tool gives you full control over your data transformation lifecycle.

With just a few clicks, you can:

  • Upload a sample file or paste in your source data.
  • Choose your output file format: JSON, CSV, or XML.
  • Select from a list of common mapping targets.
  • Save revisions to track changes.
  • Deploy mappings as versions for clarity and consistency.

Versioning That Fits Your Workflow

Each mapping shows whether it is simply saved or if it is deployed, so you can organize your workflow. Assign unique versions to specific Flows for customized mapping solutions in testing or production environments. This allows your team to move quickly while maintaining precision.

Designed for Speed and Built for Scale

Whether you're signing on a new trading partner or handling an outdated file format that you have had to consistently update manually, the Custom Mapping Tool adapts to your use case.

No back and forth with development teams. No waiting on custom code. Just fast, flexible fixes for even the most complex data.
