On Short.io, you can not only create links in bulk but also edit. The process is based on a built-in Google Sheet.
You can edit short URLs, original links, slugs, titles, UTM-tags, iOS/Android links, cloaking, expiration date/link, tags in bulk.
How to edit a bunch of links:
1. Open your Short.io account.
2. Click Bulk Edit.
3. Edit necessary data.
4. Click Save Changes.
The process may take 1-2 minutes. After that all changes will be saved. You can check them on your dashboard.
