Preview and validation are free. You decide what the fields mean.
Small, explicit support contract
Primitive fields, renames and allowlisted casts. Required fields, nullability, enums and inclusive numeric bounds. Unsupported keywords are refused. Leading-zero identifiers stay strings.
Review stays with you
This deterministic tool cannot establish business meaning. Names and types can stay the same when meaning changes. Recheck with your vendor before reusing a mapping.
Free local engine
The Apache-2.0 CLI and SDK are free. This hosted offer packages your reviewed, validated artifact without setting up a local environment. Raw uploads expire in one hour; mapping/artifact copies expire after the download window. Financial order identities are retained separately.
