<a name="ManagingWorkerDetailsOffline"></a>

If you have a large number of Workers, it's easier to manage them offline using another application, such as Microsoft Excel. This section shows how to download Worker information, edit it, and upload it.

1. On the **Manage Workers** page, choose **Download CSV**. A **Generating Workers Results** page may temporarily appear while your CSV is generated. 

1. On the **Download Workers Results** page, a dialog box appears when your CSV is ready. choose the word **here** in the first sentence to download the Worker data file.

1. The Worker data downloads and opens in Microsoft Excel. The **CURRENT-*QualName*** column shows the Worker's current qualification score. If the cell is blank, you haven't assigned the qualification type to the Worker. The far-right column, **CURRENT BlockStatus**, shows the Worker's block status.

1. To update the values, do one or more of the following:
   + Indicate which qualification type to assign a Worker by putting a qualification score in the **UPDATE-*QualName*** column. For example, **UPDATE-Good Tagger**. Qualification scores must be 0 to 100, inclusive.
   + To revoke the qualification type, enter **Revoke** in the **UPDATE** column for your qualification type.
   + Block or unblock a worker by entering **Block** or **Unblock** in the **UPDATE-BlockStatus** column.
