# FilterColumn

Type: object

Fields typed as another model are documented on that model's page; fetch it before filling the field.

| Field | Type | Required | Description | Allowed values / default / constraints |
| --- | --- | --- | --- | --- |
| `type` | string | yes | A **column** filter: choose which columns are carried through. | const: `"column"` |
| `columns` | array of string | no | The selected columns. Each is a spreadsheet column letter (`A`, `B`, … `AA`), uppercase, as in the web app — not the header name. Find letters with `GET /rest/beta/files/{provider}/{file_id}/structure?include=columns`. |  |
