For scenarios where your users are uploading data with additional columns that do not fit into your schema, Segna can capture them as additional fields (as long as your output destination is flexible as well). For more info, refer to the Column Mapping docs.
All additional fields can be then combined into one, as a JSON object keyed by each additional field's name. This can be specified on the Pipeline, by specifying which field to combine to on the Output Schema page during the Pipeline Building process.
