|Not sure this will work for you, but have you tried this:|
I’m not using 2007 so these are for pre-2007
It shouldn’t be to much trouble to convert them.
First, Highlight the cells / columns that you want to be able to import to
Then click Format
Select the Protection tab.
Uncheck the Locked check box
Next, select Tools,
Now you cannot change the column width,
But you should be able to edit only those cells / columns that are formatted as unlocked.
Once you have the data in place, if you want, just reverse the protections.
