How this LaTeX Formatter works

This specialized text processor parses LaTeX source code to apply structural indentation, transforming flat or messy TeX files into hierarchically organized documents. The algorithm identifies standard environment delimiters (\begin{...} and \end{...}), bracket groups, and command blocks, inserting configurable whitespace (spaces or tabs) to visually represent the document structure.

Unlike generic code formatters, this tool handles LaTeX-specific valid syntax that often confuses standard parsers, such as line-breaking commands (\\), math mode delimiters ($...$ or \[...\]), and optional arguments ([...]). It focuses purely on "beautification"—adjusting whitespace for readability—without altering the semantics or content of the document. This is particularly useful for researchers collaborating on papers, students debugging complex tables or equations in Overleaf, or anyone inheriting a disorganized TeX project.

The formatting runs entirely in the user's browser, ensuring that sensitive research data, unpublished manuscripts, or private thesis work remains secure and is never uploaded to external servers. It allows users to quickly clean up code before submission or collaboration, reducing merge conflicts and improving maintainability.

How to Use

1

Paste LaTeX

Paste your raw LaTeX code including environments and equations.

2

Format

Click to automatically apply indentation to \begin{} and \end{} blocks.

3

Copy

Copy the clean code back to your Overleaf project or editor.

Example Usage

Indenting an equation environment.

Input
\begin{equation} E=mc^2 \end{equation}
Output
\begin{equation} E=mc^2 \end{equation}

Frequently Asked Questions

How does it format LaTeX?
It scans for environments like \begin{...} and \end{...} and adds indentation to the content inside them. It also removes extra blank lines.
Does it check for syntax errors?
No. This is purely a "beautifier" that fixes indentation. It does not compile the LaTeX or check for missing packages.
Is it safe for my thesis/paper?
Yes. All processing is done locally in your browser. Your research data is never sent to our servers.
