## Add-in button is grayed out

**Problem**: The **GPT for Excel Word – Autosheet** button is grayed out and unclickable on the [ribbon](https://support.microsoft.com/en-US/Office/foundations-experiences/show-or-hide-the-ribbon-in-office) when you open Excel. You cannot open the add-in.

> **Solutions**
>
> - Open the add-in from the **Add-ins** menu: Select **Home > Add-ins > My Add-ins > GPT for Excel Word – Autosheet**.
>
> - Open the add-in from the **Office Add-ins** dialog: See the solution for [Add-in button becomes grayed out after click](https://autosheet.com/docs/gpt-for-excel/troubleshooting/add-in-not-working#add-in-button-becomes-grayed-out-after-click).
>
> - The add-in can be grayed out in legacy or incompatible file formats, such as `.xls`, `.ods`, or `.csv`. Save a copy of your file as `.xlsx`, or test the add-in in a new blank workbook saved as `.xlsx`.
>
> - If the add-in works in the new file, check whether the original file is protected. Protection such as **Mark as Final** turns off add-ins. Ask the file's owner to remove the protection, or work in an unprotected copy.
>
> - **Excel on Windows:** Check for a conflicting COM add-in. Excel can gray out GPT for Excel – Autosheet when a locally installed COM add-in conflicts with it.
>
>   1. In the menu bar, select **File > Options**.
>   2. In the options sidebar, select **Add-ins**.
>   3. In the **Manage** dropdown menu, select **COM Add-ins** and click **Go**.
>   4. Uncheck the boxes to disable the COM add-ins and click **OK**.
>   5. Restart Excel. If GPT for Excel – Autosheet works, re-enable the COM add-ins one at a time to find the conflicting one.
>
> - If you're using Excel in **Safe Mode**, restart it in standard mode to test GPT for Excel – Autosheet.
>
> - **Reinstall the add-in directly from Excel** if it was installed from a web browser.
>
> - If Excel itself has problems, ask your IT administrator for help. On Windows, you can also follow [Microsoft's Office repair instructions](https://support.microsoft.com/en-US/office/lifecycle/repair-an-office-application). The repair affects the entire Office installation; do not uninstall Office just to test GPT for Excel – Autosheet.
