n8n-nodes-md-formatter

MD Formatter: parse text/markdown/JSON into structured, pretty Markdown and JSON. Supports:

• Strict repeatable headings (CHARACTER_PROFILE, ## name, ...)
• Front matter (YAML) to JSON
• Delimiter splitting (---CHARACTER_START--- / ---CHARACTER_END---)
• Page number/header cleanup and chapter detection
• Export: Markdown (binary) and JSON payloads (fieldMapped, sqlIngest)

Install (development)

• In this repo folder:
  • npm install
  • npm run build

n8n usage

• Add a Function (or any node) that sets item.json.content to your raw text/JSON/markdown
• Add "MD Formatter" node after it
  • Source Type: Auto Detect (or JSON/Text)
  • Format Style: Pretty (or Strict)
  • Include Front Matter: optional
  • Detect Structure: true to normalize chapters/remove page numbers
  • Start/End Delimiter: optional to split multiple records
  • Export JSON: true → choose schema (Field-Mapped or SQL Ingest)
  • Export .md File: true → adds binary data with filename

Output:

• item.json.markdown: formatted Markdown
• item.json.fieldMapped or item.json.sqlIngest when enabled
• item.binary.data: the .md file when Export .md File is enabled

Notes

• Filename auto-generates from name when present (e.g. cormac-finnegan.md)
• Strict Markdown generator produces machine-friendly # CHARACTER_PROFILE with ## keys
