Guides, tutorials, and real-world workflows for composable document and image processing.
Run a Complete Image Processing Pipeline in One n8n Node
n8n's Edit Image node handles basics. For production pipelines — resize, crop, sharpen, watermark, convert — the Iteration Layer node runs 30 operations in a single call.
Convert Any Document to Clean Markdown in n8n
PDF, DOCX, HTML, images — convert them all to structured Markdown inside an n8n workflow. One node, no OCR chain, no LLM parsing.
Generate Formatted Excel Spreadsheets in n8n
Create multi-sheet XLSX files with formatting, formulas, and merged cells directly from n8n workflows — no code, no Google Sheets export.
Convert Markdown to Styled PDF in n8n
Turn Markdown content into professionally styled PDF documents inside n8n — with custom fonts, headers, footers, and page numbers.
One n8n Node for Your Entire Document and Image Pipeline
Most n8n document workflows chain 3-4 separate services. The Iteration Layer community node replaces them with a single node that handles extraction, transformation, and generation.
Read Any Document From Claude Code or Cursor — PDF, DOCX, Scans, Images via MCP
Use MCP to convert PDFs, scanned documents, Word files, and images to readable markdown directly from Claude Code or Cursor. No code, no pipeline.
Four APIs, One Conversation: The Composable Content Pipeline
When document extraction, image processing, and generation are MCP tools in your AI assistant, the workflow changes fundamentally.
How We Built Our Pitch Deck with Our Own API
We generated a 10-slide marketing deck using the Iteration Layer Image Generation API. No Figma, no PowerPoint — just JSON layers, layout compositing, and a mix task.
From PDF Invoices to Formatted Spreadsheets in Two API Calls
Extract structured data from PDF invoices and generate formatted XLSX spreadsheets using the Document Extraction and Sheet Generation APIs.
Sheet Generation API: Structured JSON In, Formatted Spreadsheet Out
Generate XLSX, CSV, and Markdown spreadsheets from a single API call. Structured JSON in, formatted files out.
API Composability Patterns: How to Chain Iteration Layer APIs
When to pipeline, when to parallelize, and how to handle errors across chained API calls.
Automate Your Self-Publishing Pipeline with APIs
Generate manuscripts, covers, marketing banners, and social media assets for self-publishing with a handful of API calls instead of a dozen tools.
