I will tell you a WORD application for this site, sent my way by an editor colleague, James Harbeck. (quoting him)
To randomize a list of words:
1. Paste them into one column in an Excel sheet.
2. Go to http://www.random.org/integers/ and have it generate as many numbers as you have words in one column. (It generates each one
randomly, so there can be duplicates, but that's not a big problem for what we're doing.)
3. Paste that into the next column.
4. Sort the data by the column with the numbers.
The same site also has a bunch of other fun tools, like (to name only a few)
Playing Card Shuffler
Lottery Quick Pick
Keno Quick Pick
Jazz Scale Generator
Possible Lessnesses (say what?)
