What problem does it solve? Converting files between formats usually requires hunting down the right library, remembering its API, and debugging encoding or dependency issues. This Skill provides tested one-liner recipes for dozens of conversion pairs so files can be transformed immediately without trial and error. ## Core Features & Use Cases - Data format conversion: Convert between CSV, JSON, Excel, Parquet, YAML, XML, and JSONL using pandas, pyyaml, and xmltodict, with encoding and delimiter handling built in. - Document and PDF operations: Convert documents with pandoc, extract text and tables from PDFs with pdfplumber, and merge, split, or rotate PDFs with pypdf. - Image, audio, EPUB, GIF, and ZIP handling: Convert images with Pillow and cairosvg, audio with pydub, ebooks with pandoc or ebooklib, and create or extract ZIP archives with the standard library. - Use Case: A user uploads an iPhone HEIC photo and a FLAC audio recording, then asks for a JPG and an MP3. The Skill locates the uploaded files, applies pillow-heif and pydub conversions, and validates the outputs. ## Quick Start Convert the uploaded file report.docx into a PDF and also extract the first three pages as a separate document.
