Latex Document

Latex Document is a cloud-based skill for creating, compiling, and converting LaTeX documents into professional PDFs with instant PNG previews—no local installation needed.

What Is This?

• Full access to the LaTeX typesetting system through HappyCapy, with cloud compilation and instant PDF output
• Support for resumes, academic papers, presentations, invoices, scientific posters, and fillable forms
• Advanced features including mail merge from CSV/JSON, version diffing, CJK language support, and PDF-to-LaTeX conversion

Why Use It?

• Superior typographic quality: Mathematical equations, tables, and scientific notation render with precision that word processors cannot match
• Eliminate manual errors: Cross-references, bibliographies, and numbering are handled automatically
• Automate document production: Generate batches of personalized letters, certificates, or invoices from structured data
• No setup required: Everything compiles in the cloud; no local LaTeX distribution or package management needed

How to Use It?

Provide your LaTeX source code and any required data files. The skill compiles and returns a PDF with PNG previews.

Simple report example:

\documentclass{article}
\usepackage{geometry}
\geometry{margin=1in}
\title{Quarterly Report}
\author{Jane Smith}
\date{\today}
\begin{document}
\maketitle
\section{Introduction}
This report summarizes Q3 performance metrics.
\section{Results}
Revenue increased by 12 percent compared to the prior quarter.
\end{document}

Beamer presentation example:

\documentclass{beamer}
\title{Research Overview}
\author{Dr. Lee}
\begin{document}
\begin{frame}
\titlepage
\end{frame}
\begin{frame}{Key Findings}
\begin{itemize}
  \item Finding one
  \item Finding two
\end{itemize}
\end{frame}
\end{document}

For mail merge, supply a JSON or CSV data file with a template using placeholder variables. Charts and tables work through pgfplots and booktabs; Mermaid diagrams and images can be embedded.

When to Use It?

• Academic submissions requiring specific formatting, technical reports with equations and figures, or professional documents where typographic quality matters
• Automating document production at scale—generating fifty personalized invoices from a spreadsheet or producing versioned thesis drafts with tracked changes
• Multi-language documents with CJK scripts (Chinese, Japanese, Korean) where standard tools struggle with encoding and font rendering

Important Notes

• LaTeX syntax errors prevent compilation; review source carefully and ensure all referenced packages are standard or explicitly included
• For CJK documents, specify correct encoding and font packages such as xeCJK with XeLaTeX
• Validate data file structure against template variables before running large mail merge batches
