I'd like to, if possible, add functionality to paste from a spreadsheet (Excel or Google Docs) into a "grid add" page. In my mind, it would go something like this: add custom server-side code to make a textbox and a "fill" button. The user pastes his spreadsheet data and clicks the button. There is then some custom javascript that parses the data in the box (default format is tab-delimited from Excel and Google docs, so pretty easy) and fills in the table with this information when the fill button is clicked.
This is pretty easy to do with JQuery. I'm just not sure how to select the correct text boxes (as in, 3rd text box of 5th row, etc). Any suggestions?
And is there a way to make this as a plugin as well?
