From Microsoft: converts PDF, Word, Excel, PowerPoint, HTML and other files or URLs to Markdown so agents can read and search them. A single convert_to_markdown tool over STDIO or local HTTP.

Converts PDF, Word, Excel, PowerPoint, HTML, images, audio and more into Markdown that keeps headings, lists and tables, ready for LLMs to read and analyze. Maintained by Microsoft; requires Python 3.10+.

Anthropic's document skills, the implementation behind Claude's file features: create, edit and analyze Word, Excel, PowerPoint and PDF files, including tracked changes, comments, formulas and form filling. Source-available, not under an open-source license.

From Firecrawl: converts Word, PowerPoint, Excel, PDF, EPUB, RTF and more into clean Markdown locally in milliseconds, keeping headings, tables, footnotes and formulas so agents can read attachments. Needs Node.js; optional Firecrawl cloud OCR for scans uploads the whole file.

Document layout skill by tw93 with eight templates (resume, one-pager, long doc, formal letter, portfolio, slides, research report and more) that render polished PDF, PNG or editable PPT and check layout and content gaps. Supports English, Chinese, Japanese and Korean. Needs Python (WeasyPrint).

Turns a paper (arXiv link or PDF) into method diagrams, slides with a generated image per page (PPTX/PDF export) and an in-depth HTML explainer with formulas, for lab meetings and lectures. No API key; images use Codex's built-in generator or, in Claude Code, a separate image skill.

DeepL's official CLI: translate text and PDF, Word, PowerPoint and Excel documents while keeping formatting, with glossaries and translation memory. Needs a DeepL API key (free plan available); install from source with Node.js 24.15+. Have legal translations reviewed.
