Please give it a try and let me know how it works for you and if you run into any issues with it. This module is something I've had in the works for awhile, and regularly use on various projects, so figured I should clean it up a bit and release it. Also attached are a couple screenshots from it.
How to Install:
1. Download from: https://github.com/r.../ImportPagesCSV
2. Place the file ImportPagesCSV.module in your /site/modules/ directory.
3. In ProcessWire admin, click to 'Modules' and 'Check for new modules'.
4. Click 'install' next to the 'Import Pages CSV' module (under heading 'Import').
Following that, you'll see a new menu option for this module on your Admin > Setup menu.
Supported field types for importing:*
- Textarea (including normal or TinyMCE)
- Checkbox (single)
