The Feeds Editor module intended to make your life easier when you work with CSV files for Feeds importers.
For each existing Feeds importer (admin/structure/feeds) you can create a "worksheet".
Each worksheet has its own frontend (UI) and backend.
The frontend looks like MS Exel table and based on excellent JQGrid plugin(see http://www.trirand.com/blog/jqgrid/jqgrid.html).
Via UI you can perform various administrative tasks such as:
- Add rows
- Edit rows (modal window, inline)
- Search columns
- Sort columns
So, what's special?
When you create a CSV file locally using, for example MS Exel or Openoffice, and have many different fields, you must properly enter all those values.
You have to remember all of them or check every time possible values in the field's settings. It's boring and slow process.
Another good example - images.
You have to upload all your images manually to the server, most likely using FTP client, than get their URLs and paste into appropriate table cell.
With Feeds Editor module you can open modal window and quickly upload multiple images at once using Plupload widget, then easy copy-paste recieved URLs
When you add a row, you also add corresponding record to backend (working) table.
