# Refresh Data

{% hint style="warning" %}
**Prerequisites:**

* You have access to the **Data Center > My Connectors > Data Sheets**.
* The target Data Sheet is **sandbox-based** (created from a Data Sandbox file).
* You have permission to **refresh** that Data Sheet.
  {% endhint %}

### Steps to refresh a Data Sheet

1. **Open Data Sheets**
   * Navigate to **Data Center > My Connectors > Data Sheets > Data Sheet List**
2. **Select a sandbox-based Data Sheet**
   * Locate the Data Sheet that was created from a **Data Sandbox** file from the Data Sheet list.
3. **Start refresh**
   * Click the **Refresh Data** icon for the selected Data Sheet.
   * **Result:** A notification appears confirming the **data refresh has started**.
4. **Monitor progress**
   * Click the **Notifications** (bell) icon on the top bar.
   * In **Last 3 Unread** notifications, click the refresh job entry to open details.
5. **Review outcome**
   * The **Notifications** page opens, showing whether the data **loaded successfully** into the selected Data Sheet (or any error details if the refresh failed).

{% hint style="info" %}
**Notes & Tips:**

* The **Refresh Data** action is available **only** for Data Sheets backed by **Data Sandbox** sources.
* If the source is an **Excel (.xlsx)** with multiple sheets, the refresh uses the **sheet configured** when the Data Sheet was created.
* Refresh runs asynchronously; use **Notifications** to verify completion.
* If the source file was **replaced/updated** in Data Sandbox, run **Refresh Data** to sync the changes into the Data Sheet.
* Keep the Data Sheet and source file **column structures aligned** to avoid mapping errors during refresh.
  {% endhint %}

### Troubleshooting

* **Refresh icon not visible/disabled:** Confirm the Data Sheet is **sandbox-based** and you have refresh permissions.
* **Refresh completes with errors:**
  * Check that the **source file** still exists and is accessible.
  * Verify the **sheet name/structure** hasn’t changed.
  * Reopen the Data Sheet after resolving issues and try again.
* **No apparent changes after refresh:** Ensure you refreshed the correct Data Sheet and that the **source file** actually contains new/updated data.
