Every format you'll meet
JSON, XML, CSV, YAML, Protobuf, Avro, Parquet, flat file, COBOL copybook and EDI.
Data Transformation
Transform any data, any format, at native speed.
GoWeave gives you a DataWeave-style language. The Visual Mapper handles simple mappings without code.
GoWeave
GoWeave transformation language
A concise, expression-based language for JSON, XML and CSV, with functions such as map, filter, reduce, groupBy, orderBy, distinctBy, pluck, flatten, joinBy, splitBy and when/otherwise.
DataWeave compatibility
Existing DataWeave 2.0 scripts are converted to native code automatically, so your transformation logic survives migration.
How migration works%dw 2.0 output application/json --- payload.orders filter ((o) -> o.status == "SHIPPED") groupBy ((o) -> o.region) mapObject ((orders, region) -> { (region): { count: sizeOf(orders), total: orders reduce ((o, acc = 0) -> acc + o.amount), customers: orders distinctBy $.customer map $.customer } })
// GoWeave output json --- payload.orders | filter(o => o.status == "SHIPPED") | groupBy(o => o.region) | mapObject((orders, region) => { (region): { count: sizeOf(orders), total: orders | reduce((o, acc = 0) => acc + o.amount), customers: orders | distinctBy(o => o.customer) | pluck("customer") } })
{
"EMEA": {
"count": 2,
"total": 1840.5,
"customers": ["C-1001", "C-1042"]
},
"APAC": {
"count": 1,
"total": 615.0,
"customers": ["C-2007"]
}
}
Illustrative example. GoWeave syntax shown for comparison; generated output varies by script.
Build transformations faster
Write it, see it, or map it visually.
Live preview
Paste sample input, define input and output schemas, and watch the output update as you type.
- Sample input for JSON, XML and CSV
- Input and output schemas
- Output updates as you type
// input (sample.json) { "first": "Ada", "last": "Lovelace", "tier": "gold" } // script { name: payload.first ++ " " ++ payload.last, vip: when payload.tier == "gold" then true otherwise false } // preview { "name": "Ada Lovelace", "vip": true }
Visual Mapper
Map fields between source and target with no scripting.
Ideal for straightforward mappings, and a quick way for new team members to get productive.
SourceTarget
customer.idcontact.externalId
customer.full_namecontact.name
customer.emailcontact.email
customer.countrycontact.address.country
Beyond mapping
Everything you need to shape, query and validate data.
Query and validate
XPath, XQuery, XSLT, JSONPath and JMESPath, plus JSON Schema, XSD and OpenAPI validation.
Templates
Mustache and parse-template support for generating documents and messages.
Supported formats
One transformation layer for every payload.
Read in one format, write in another, and validate along the way, all compiled into your Go microservice.
