SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Working with documents across formats requires juggling many tools: converting DOCX to PDF, extracting text from scanned files, redacting PII before sharing, and filling PDF forms manually. This Skill consolidates all of these operations into a single API-driven workflow. ## Core Features & Use Cases - Format Conversion: Convert between PDF, DOCX, XLSX, PPTX, HTML, and image formats via the Nutrient DWS Processor API. - OCR and Extraction: Extract text and tables from documents, and OCR scanned files in 100+ languages to produce searchable PDFs. - Redaction, Signing, and Forms: Redact PII using presets or regex, add watermarks, apply digital signatures, and fill PDF form fields programmatically. - Use Case: Before sharing a contract PDF externally, redact all social security numbers and email addresses, add a CONFIDENTIAL watermark, and apply a digital signature in one workflow. ## Quick Start Set the NUTRIENT_API_KEY environment variable and ask the agent to convert a DOCX file to PDF or redact sensitive data from a document.
