What is a CSRD XHTML Report?
Under the Corporate Sustainability Reporting Directive (CSRD), companies must publish their ESG disclosures in a machine-readable XHTML format, embedding XBRL tags that make the report structured and standardized.

These files must follow strict formatting and tagging rules to ensure compliance, traceability, and accessibility for both regulators and analysts.

Who is this template for?
This workflow is designed for sustainability teams, ESG consultants, or developers who want to automatically check the structure and format of CSRD reports submitted in XHTML.

How does it work?
This N8N workflow automates the audit process:
📤 Input Node → Uploads or fetches the XHTML file via URL or Webhook.
🧪 Validates Structure → Uses a custom code node to parse HTML and identify required tags (e.g., <ix:nonNumeric>, namespaces).
📋 Outputs a Report → Returns a summary report of errors, warnings, and key metadata (like entity name, reporting period).
📤 Export Option → Save the results in Google Sheets or send via email.

Prerequisite
A sample XHTML file that you can find in my GitHub Repository Google Sheets API* and OpenAI API* credentials

Next Steps
Follow the sticky notes inside each node to adjust parsing rules or extend validation to specific XBRL tags relevant to your sector (e.g., GHG emissions, water usage).

Notes
This workflow includes an example XHTML file to test the validator.
You can plug this into your internal systems or even extend it with AI to auto-summarize the sustainability report.

This workflow has been created with N8N 1.82.1
