Why openxml-office

One Rust core

A single, well-tested engine does the heavy lifting, so behaviour stays consistent no matter which language you call it from.

Multi-language bindings

Native packages for .NET, Go, Node.js and Python ship through each ecosystem's own package manager — no extra runtime dependencies.

Developer-first API

Intuitive namespaces and helpers, designed for IDE auto-completion and an efficient, in-process workflow.

Office-compatible output

Targets Microsoft Office 2013 and newer, producing files that open cleanly in the apps your users already have.
