# Update column

Updates properties of the column, moves the column, or renames the column.

> Important:
>
> - You cannot change the type of a Primary Column.
>
> - If you change the type, all cells in the column are converted to
the new column type, and column validation is cleared.
>
> - The type property is optional when moving or renaming a column, but it's required when changing symbol, systemColumnType, options, contactOptions, or autoNumberFormat.
>
> - When setting a column type of PICKLIST or MULTI_PICKLIST, you must follow a one update per API call rule. For these column types, you must set the column type first, before making any additional constraints (such as setting validation to true) in subsequent calls.
>
> - Column options are forbidden in the request body when the body specifies a symbol update.
>
> - While dependencies are enabled on a sheet, you can't change the type of any calendar column, Gantt column, or Resource Management column. Such columns have a tags array that contains at least one of the following enum values:
>
>   - CALENDAR_END_DATE
>   - CALENDAR_START_DATE
>   - CARD_DONE
>   - GANTT_ALLOCATION
>   - GANTT_ASSIGNED_RESOURCE
>   - GANTT_DISPLAY_LABEL
>   - GANTT_DURATION
>   - GANTT_END_DATE
>   - GANTT_PERCENT_COMPLETE
>   - GANTT_PREDECESSOR
>   - GANTT_START_DATE
>   - BASELINE_START_DATE
>   - BASELINE_END_DATE
>   - BASELINE_VARIANCE
