# Upload Sub-Tag

In addition to adding subtags one by one, you can also upload multiple subtags at once using the **'Upload'** button located in the top-right corner of the page. After clicking this button, an **Upload Tag** pop-up will appear, as shown in the following image.

Before uploading, you need to download the tag template first by clicking the **'Download Template'** button. After opening the template file, it will appear as shown in the following image.

{% hint style="info" %}
In the template file, each subtag is separated using a hyphen (-) to indicate the hierarchical tag structure.
{% endhint %}
