What is a LATEX file

Its contents are saved as text representing text data, directives, macros, and references to fragments and other information which is used to create a technical or scientific document. A LaTeX document is created with a plain text editor and transpiled to a different document format such as HTML or PDF using LaTeX and other TeX-based applications.
