# Exclude

Exclude generation can be especially useful in the following situations:

1. When data neither contain necessary nor useful data.

## Apply Exclude

1. Open your **Workspace**.
2. From the **Main hub** or **Table view** tab, select the column where you want to apply a generator.
3. Under **Generator,** select **Exclude** to exclude the column from the generation job.
4. Select **Confirm**.

**Note:** When you exclude a column, data will not be read, so it can be used to reduce hardware requirements or increase the speed of your synthetic data jobs, e.g. by excluding large text or blob columns.
{% endhint %}
