Show HN: LibreOffice-rs – I built a pure-Rust LibreOffice using autoresearch

Hey HN, I built libreoffice-rs: a pure-Rust, std-only library + CLI for reading, writing, converting, and rendering office documents — with *zero* LibreOffice, Java, or C dependencies. 100x faster... I know, I know. It supports DOCX, XLSX, PPTX, ODT/ODS/ODP, PDF, Markdown, CSV, HTML, SVG, and more. The CLI is designed to feel familiar: ```bash cargo install libreoffice-pure # soffice-style usage libreoffice-pure --headless --convert-to pdf report.docx libreoffice-pure --headless --convert-to csv spreadsheet.xlsx # Markdown extraction libreoffice-pure docx-to-md report.docx report.md libreoffice-pure pptx-to-md slides.pptx slides.md # Render pages as images libreoffice-pure docx-to-pngs report.docx pages/ --dpi 144 ```
