Can I change a lot of things at once?

Yes, with Bulk Edit. Open the Advanced section in the left menu (it starts closed, so click the word Advanced), then click Bulk Edit.

1. Export your site's content as a spreadsheet file.
2. Change many rows at once in a spreadsheet program.
3. Import the file back in.
4. A preview shows you exactly what will change before anything goes live.

This is powerful, but it's easy to overreach. One wrong column can change many pages at the same time. Move carefully and read the preview.

You can skip Bulk Edit entirely and still run your whole site. If you have a big change in mind, the support team can help you with it.

Why this matters

For a big batch of changes, this saves you clicking through pages one by one. But it's a sharp tool, so use it only when you really need it.
