I have been given a large notebook that was created in mathematica 6. It contains a structure of sections and subsections and the input text is formatted in an unusual (possibly just old) style (see screen grab below).
My main aim is to update the formatting of the input cells to the standard mathematica 8 format as I find this format much easier to read/debug (example below).
My first thought was to simply copy the entire notebook into a text editor and then copy back into a notebook. However, this results in the generation of a single large input cell that is prohibitively tedious to break up...
Applying a new stylesheet does not change the input cell style.
Is it possible to update the formatting/style throughout a notebook whilst preserving the cell structure and hierarchy?
Edit: An excerpt from the original notebook can be found here,
and here is the same excerpt after clearing formatting (but without syntax highlighting).
