# Editing your configuration
Configuration editing

You can use the **Import and Export** feature to edit your server configuration, including bulk changes:

1. Export the data to a CSV file.

1. Edit your file.

1. Import the edited file back into the service.

**Note**  
 When editing a CSV file in Microsoft Excel be sure to save it in the **MS-DOS** CSV data format. 

When processing the inventory file import, values provided in the file overwrite existing values. *Cells that are empty are ignored*. This allows you, when editing the file, to include values only in the inventory columns that you want to overwrite.

To delete a value replace the existing value with the string `[RESET_VALUE]` and then save and upload the file. This clears the value in the Application Migration Service resource or the Amazon EC2 launch template.

Using `[RESET_VALUE]` is available for these parameters:
+ mgn:launch:iam-instance-profile:name
+ mgn:launch:nic:0:network-interface-id
+ mgn:launch:nic:0:private-ip:0
+ mgn:launch:nic:0:security-group-id:0
+ mgn:launch:nic:0:subnet-id
+ mgn:launch:tag:instance:key1
+ mgn:launch:volume:/dev/sda:type

You can also delete tag fields. To delete the tag value replace the existing value with the string `[RESET_VALUE]`. To delete both the key and the value replace the existing value with the string `[DELETE_TAG]`. 

**Note**  
Tags that are created by the service, such as `AWSApplicationMigrationServiceManaged`, can't be changed or deleted. Attempting to do so results in an error.
