Well-formatted LaTeX source code is easier to read, debug, and collaborate on. The FormaTeX formatter uses latexindent to apply consistent indentation, spacing, and line breaks to your .tex files.
Paste messy LaTeX into the input panel and click Format. The beautified output appears instantly on the right. You can copy it or replace your input with one click.
Proper formatting is especially important for large documents with nested environments, complex tables, and multi-file projects where readability matters.
Every tool on this page is powered by the FormaTeX REST API. Integrate the same capabilities into your own apps with a few lines of code.
