# Import components from CSV mapping

`POST /data_structures/import_components_csv/{id}`

Add components to an existing draft data structure using a CSV file and column mapping. Multipart form with `file` (CSV) and `payload` (JSON string), or JSON body with `upload_id` (completed resumable upload) plus mapping fields. Payload shape: `{ delimiter, dry_run?, overwrite?, components: [{ name, label, column_type, csv_column, codelist?: { mode: global|from_csv, ... } }] }`. Codelists created from CSV use maintainable id `CL_{component_name}` under the structure agency.
