json-mapper
Map, transform, and validate source data into JSON conforming to a target JSON Schema.
README
json-mapper
An agent skill that maps, transforms, and validates arbitrary source data into JSON that conforms to a target JSON Schema.
What it does
Turn arbitrary source data (CSV, spreadsheets, JSON, XML, API payloads, or free-form text/documents) into a JSON document that conforms to a given JSON Schema — then validate it. The skill's core principle is to not silently guess: when a mapping decision is genuinely ambiguous (date formats, enum members, branching schemas, missing required fields), it asks the user targeted, batched questions instead of producing confidently-incorrect data.
