Hi everybody.

I received two documents, formatted as you can see in the image below.
Both texts (on the right) generate the table of contents that you can see on the left.

The problem is that headings have a different formatting styles, as you can see on the top. How is that possible?

My goal is to have the first document formatted as the second one.
Is there a shortcut to take all the ABC-level headings (Heading 1 style) and format them accordingly (same process for all the CDE-level headings - Heading 2 style, etc.) without having to do it one by one (considering it's a long document)?
