## Summary

During the _Map Columns_ step of the file import process, you can **duplicate columns**. Once created, these columns can be mapped to a MindBridge column, or [added for additional filtering](https://support.mindbridge.ai/hc/en-us/articles/360058269853) in the analysis results.

Learn how to duplicate a column within an analysis in MindBridge.

**Note:** In order to duplicate columns, you must have [created an analysis](https://support.mindbridge.ai/hc/en-us/articles/360057583093) and begun [importing files](https://support.mindbridge.ai/hc/en-us/sections/4408298361879) into it.

## Duplicate a column

1. Under _Your Data Column Headers_, select the **more actions icon**(  ) to the right of the column you want to duplicate.
2. Select **Duplicate column**. A form window will appear with a preview of the first 2 cells in the selected column.
3. Enter a new name for the duplicated column in the **Header name** field.
4. **Save** your work. The duplicated column will appear at the bottom of your column list on the _Map Columns_ step and can be identified by the blue dot in the upper right corner of its name.

Select **Cancel** any time to go back to the _Map Columns_ step without duplicating a column.
