About Field Mapper

Field Mapper helps you create field-to-field mappings between source and target data schemas. Paste JSON or CSV sample data to automatically extract source fields, define your target schema, and map fields using dropdown selectors. Mappings can be saved to your browser, loaded later, and exported as JSON for use in ETL pipelines and data integration workflows.

Supported Formats

JSON - Single objects, arrays of objects, or nested structures (dot-notation paths are extracted)
CSV - Comma-separated values with headers in the first row
