## What it is
UniOffice is a pure Go library for creating, reading, and editing Office Open XML documents: Word (.docx), Excel (.xlsx), and PowerPoint (.pptx). It is a commercial product requiring a license key, offering formatting, images, tables, charts, formula evaluation, and DOCX-to-PDF conversion with no external dependencies.

## Use cases
- generate word documents from templates in go
- create excel spreadsheets programmatically
- read and edit docx files in a go application
- evaluate excel formulas in xlsx files
- convert docx to pdf without office installed
- build powerpoint presentations from data
- extract cell values from xlsx spreadsheets

## When to choose
- you need a high-performance, pure-Go (no CGO) solution for OOXML documents
- you need to create, edit, and read docx, xlsx, and pptx in one library
- you need commercial support, licensing, and air-gapped deployment options
- you need formula evaluation or DOCX-to-PDF conversion in Go

## When to avoid
- you need a fully open-source library with a permissive license (it uses a commercial EULA)
- you only need simple spreadsheet reading and want a free alternative
- your project is not written in Go

## Facets
- artifact type: library
- maturity: active
- function: serialization, pdf, data-science
- domain: files, spreadsheets, developer-tools
- platform: go, cross-platform
- tags: docx, xlsx, pptx, ooxml, office-documents, commercial-license, pure-go, document-generation, formula-evaluation, automation
