# Tools

![PrestaShop Amazon Marketplace – Tools Tab](https://storage.crisp.chat/users/helpdesk/website/-/3/f/a/8/3fa8ee645cd13200/prestashop-amazon-marketplace-_1n3g5mm.jpg)

The **Tools** tab provides several key functions to help manage product identifiers, import valid Amazon values, and review pending synchronization actions.

## Product Reference File

This **import/export tool** allows you to quickly edit **EAN/UPC codes** and **SKUs (product references)** in PrestaShop.  

➡️ See the dedicated documentation:  
👉 [Product References and Codes Import/Export Tool](https://doc.common-services.com/en/article/product-references-and-codes-importexport-tool-1l5u09j/)

> Use this tool to prepare your catalog or correct product identifiers efficiently, without editing them one by one in the product sheet.

## Valid Values Table

This function refreshes the list of **valid values recognized by Amazon** (accepted attributes such as material, color, etc.).

🔄 It is **highly recommended** to update this table **before creating products**, to ensure your listings are compliant with Amazon requirements.

## Queue

This section displays the **list of actions** generated by [logging](https://doc.common-services.com/en/article/understanding-logging-ypan2u/):

* Product/offer creation, updates, or deletions  
* Pending synchronization tasks waiting to be sent to Amazon  

🧹 If needed, you can [empty the queue](https://doc.common-services.com/en/article/empty-the-queue-12abp9o/) to reset synchronization actions.
