noun
gibberish
JIB-er-ish/ˈdʒɪbərɪʃ/
Speech or writing that makes no sense.
The page contains gibberish rather than meaningful sentences.

Etymology
Gibberish imitates the sound of chatter and was probably influenced by jabber. Its early sense of rapid, inarticulate speech connects directly to speech or writing whose meaning cannot be understood.
In context
whoever wrote it seemed to truly understand what they were writing. The script flows like natural language, not random gibberish
