Why Word to LaTeX Conversion Breaks (And What to Do About It)

A technical look at why automated tools fail on academic papers — and what actually works. If you've ever tried to convert a Word document to LaTeX using Pandoc or an online converter, you already know how this ends. The text comes through fine. Everything else doesn't. We've handled hundreds of Word to LaTeX conversion projects at The LaTeX Lab — IEEE papers, Springer submissions, Elsevier articles, conference proceedings. The same failure modes show up every time. Here's what's actually going wrong under the hood. Why Pandoc Fails on Academic Papers Pandoc is genuinely impressive for what it does. But the way it handles equations reveals a core limitation: it converts Word's OOXML math format to LaTeX by pattern-matching, not by understanding mathematical structure. The result is that simple inline equations often convert correctly. Anything structurally complex — nested fractions, matrix environments, multi-line align blocks, custom operators — gets either mangled or exported as an
