LibreOffice-rs – I built a pure-Rust LibreOffice using autoresearch

In plain words

LibreOffice-rs is a pure-Rust library and command-line tool for reading, writing, converting, and rendering office documents without requiring LibreOffice, Java, or C dependencies. It supports DOCX, XLSX, PPTX, ODT, ODS, ODP, PDF, Markdown, CSV, HTML, and SVG formats. Users can convert between formats, extract content to Markdown, and render document pages as images through a command-line interface modeled after LibreOffice's standard usage patterns. The tool is designed for developers who need document processing functionality in Rust projects.

In the maker’s words, at launch

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 ```

  Doxx – Terminal .docx viewer inspired by Glow2025 · github.com · ▲261

  I got tired of open file.docx → wait 8 seconds → close Word just to read a document, so I built a terminal-native Word viewer! What it does: * View `.docx` files directly in your terminal with (mostly) proper formatting * Tables actually look like tables (with Unicode borders!) * Nested lists work correctly with indentation * Full-text search with highlighting * Copy content straight to clipboard with `c` * Export to markdown/CSV/JSON Why I made this: Working on servers over SSH, I constantly hit Word docs I needed to check quickly. The existing solutions I'm aware of either strip…

  Open-source .docx editor library for building document appsMay 2026 · github.com · ▲107

  We are working on an open-source .docx editor library for apps that need to edit Word documents in the browser. We just shipped 1.0. A lot of existing approaches convert .docx into HTML and lose document semantics along the way. Our editor parses OOXML directly and uses its own rendering+layout engine to produce paged documents with html/css. Edits round-trip back to .docx, so you’re always editing the document, not its representation. The core rendering engine is framework agnostic, with React and Vue ui adapters on top. It’s Apache 2.0. Happy to answer questions.

  RenderCV – Open-source CV/resume generator, YAML to PDFDec 2025 · github.com · ▲100

  I built RenderCV because Word kept breaking my layout and LaTeX was overkill. I wanted my CV as a single YAML file (content, design, margins, everything) that I could render with one command. Run rendercv render cv.yaml → get a perfectly typeset PDF. Highlights: 1. Version-controllable: Your CV is just text. Diff it, tag it. 2. LLM-friendly: Paste into ChatGPT, tailor to a job description, paste back, render. Batch-produce variants with terminal AI agents. 3. Perfect typography: Typst under the hood handles pixel-perfect alignment and spacing. 4. Full design control: Margins, fonts, colors,…

  Rudoc – a 4.5MB Rust document converterJul 2026 · github.com · ▲17

  I built Rudoc because I wanted a smaller tool for simple file convertion workflow. (Pandoc was so heavy for me) I once wanted to try Pandoc, but after I downloaded it from GitHub, I found that it is around 70 MB. It also needed a lot of dependencies. Rudoc is not a substitue of Pandoc, it supports limited set of formats (only txt, md, html, typ, docx, pdf, pptx, xml, json) and doesn't support advanced formatting. The most common workflow is just turn a markdown file to a html. PDF generation can work without Typst, but PDF input conversion requires Typst as a backend. It has no other runtime…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
