If you can code (it’s easy in VB.NET, and easier in Python), you can quickly swap 0’s for 1’s and vice versa, then convert binary to a string.

Otherwise, you can use the Find & Replace function in MS word to swap the 0’s and 1’s, then just find a binary to text converter with a Google search. Really, you can copy and paste the whole thing; just remove the last 5 characters. They’ll throw off the conversion because they make the whole thing not fit in 8-bit chunks.
