# Remove assets

You can remove assets from your inventory by submitting an asset removal request, in the form of a CSV file, through the Cortex Xpanse UI. After you've submitted an asset removal request, the requested assets appear in the **Asset Uploads/Removal** table with the status **Removed**. Within 24 hours of submitting the request, Cortex Xpanse will remove the assets from the inventory and remove associated alerts, incidents, and services,

## **Guidelines and restrictions for asset removals**

Before you submit an asset removal request, familiarize yourself with the following guidelines and restrictions:

* You can remove domains (paid-level domains and subdomains), certificates, and IPv4 ranges. Removal of IPv6 ranges is not supported.
* The asset removal request CSV file must be less than 2 MB.
* You cannot remove an asset that was uploaded in a previous upload request. This will cause an error that must be fixed before you can submit the upload request.
* When you remove a paid-level domain, related subdomains are also removed.
* When you remove an IPv4 range, the individual IPv4 addresses in that range are also removed.
* You can undo a removal request, which will result in the asset being added back to your inventory. See [Undo an asset removal](/cortex-xpanse/inventory/upload-or-remove-assets/undo-an-asset-removal.md) for more information.
* Removing assets will not result in a reduction to your contract price. Contract pricing will be reevaluated at the time of contract renewal.

### Note

If an asset removal request has an incorrectly formatted CSV or includes one or more invalid assets, the entire request will fail, and none of the assets will be removed. If this happens, Cortex Xpanse will display an error message indicating what caused the error, so you can fix the problem and resubmit if you choose.

## How to submit an asset removal request

An asset removal request is a CSV file that lists all the assets you want to remove from your inventory. It is important that the data and formatting of the CSV file are correct, or the entire request might be rejected.

1. Create and save a CSV file that lists the assets you want to remove from your inventory. Be sure to provide the correct asset information and follow the formatting requirements described in [CSV format for removal requests](#UUID-c883e9be-0129-c0d8-dc34-cdd45465bc1b_section-idm234627043560313).
2. Navigate to **Settings** → **Configurations** → **Asset Management** → **Asset Uploads/Removals**.
3. Click on the **Asset Upload/Removal** button and select **Remove Asset(s)**.
4. Drag and drop or browse to your CSV file to upload it to Cortex Xpanse.

   As soon as the file has been successfully uploaded, the assets will appear in the **Asset Uploads/Removals** table with the status **Removed**. Within 24 hours, the assets will be removed from the inventory and related incidents, alerts, and services will also be removed.

## **CSV format for asset removal requests**

An asset removal request is a CSV file that lists the assets you want to remove from the inventory. It is important to format the CSV file to match the following requirements. Incorrect formatting or typos may cause the upload to fail.

### **Remove request example**

This example shows the correct CSV format for an asset removal request, including the supported asset types and IP range notation. The headers in your CSV must match the headers shown here.

| AssetType   | Asset               |
| ----------- | ------------------- |
| Domain      | example.com         |
| Domain      | example1.com        |
| IPv4\_Range | 192.0.2.0/32        |
| IPv4\_Range | 192.0.2.0-192.0.2.0 |
| IPv4\_Range | 192.0.2.0-192.0.24  |
| IPv4\_Range | 192.0.2.0/27        |

### **Remove request CSV details**

The following table provides details about each field that is required in an asset removal request CSV file.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-xpanse/inventory/upload-or-remove-assets/remove-assets.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
