### Paste the Custom Format

In the empty `Custom Format JSON` box (1) you just paste the `JSON` that you got from the [Custom Format Collection](/Sonarr/sonarr-collection-of-custom-formats/){:target="\_blank" rel="noopener noreferrer"} or provided to you from other sources followed by the `Import` button (2).

### Save the Custom Format

After selecting the `Import` button you will get a screen that has all the Custom Format variables filled in correctly, all you need to do now is click on the `Save` button and you're done.

### Guide sync tool

!!! info "You can also use a [Guide sync tool](/Guide-Sync/){:target="\_blank" rel="noopener noreferrer"} to sync the Custom Formats or even the complete quality profile(s)."
