It's VTL, but treated like a real language
Mapping Tool has everything you need to build perfect templates...
Syntax Highlighting
Easily differentiate VTL from plain text or JSON. Purpose-built and very colorful.
Code Completion
Build faster with intelligent variable, property, method, and directive suggestions.
Reference Checking
Ensure you're only accessing variables, methods, and context properties that actually exist.
Type System
Prevent mistakes and get useful suggestions, even when a variable's type changes.
Inline Documentation
Full VTL, AWS, and Java documentation including parameter info and return types.
High Fidelity Emulation
More accurate than AWS emulators. Be confident your templates will work when deployed.
Step-through Debugging
Coming Soon
Go line-by-line until your mapping template is perfect.
JSON Schema Validation
Coming Soon
Validate output against an AWS API or custom schema.
Easy on the eyes
Designed to help you confidently navigate mapping templates, easily differentiate VTL from plain text, and quickly identify syntax errors. Plus, it's very colorful.
It's all there
Code completion, documentation, snippets, parameter hints. Covering VTL, AWS-specific context/utilities, Java methods, and even variables declared elsewhere in the template.
You're in control
Customize any input value or context property, or generate example data at the click of a button. Mapping Tool will guide you and help avoid mistakes.
No more bugs
Say goodbye to missing parameters, methods and properties that don't exist, syntax errors, weird AWS quirks, and more.
But wait, there's more...
Snippets
Save some keystrokes and brain power by using directive snippets.
Hover
Quickly check variable types and read documentation by hovering over anything.
Custom Context
Complete control over all input values and context properties.
Generate Data
Save time and avoid typos by generating example context data.
Share
Get help, help others, or show off your template with a sharable URL.
Dark mode
Because looking at VTL is bad enough for your eyes.
Import/Export
Save your template in a JSON file and import it again later.
