Notice

Community nodes can only be installed on self-hosted instances of n8n.

What this workflow does

  • Change the requested HTML to PDF..
  • Extract text from the PDF.
  • Use a Code node to handle URLs that point to PDF files.
  • Convert the PDF to text.

Requirements

  • Self-hosted n8n instance.
  • CustomJS API key for converting PDF to text.
  • HTML Data to convert PDF files.
  • Code node for handling URL that indicates PDF file.

Workflow Steps:

  1. Manual Trigger:

    • Runs with user interaction.
  2. HTML to PDF:

    • Request HTML Data
    • Convert HTML to PDF
  3. Convert PDF to Text:

    • Convert the generated Text from PDF

Usage

Get API key from customJS

  • Sign up to customJS platform.
  • Navigate to your profile page
  • Press "Show" button to get API key

Set Credentials for CustomJS API on n8n

Copy and paste your API key generated from CustomJS here.

Design workflow

  • A Manual Trigger for starting workflow.
  • HTTP Request Nodes for downloading PDF files.
  • Code node for handling URL that indicates PDF file.
  • Convert PDF to Text.

You can replace logic for triggering and returning results. For example, you can trigger this workflow by calling a webhook and get a result as a response from webhook. Simply replace Manual Trigger and Write to Disk nodes.

4. Reproducing the Workflow from Scratch

  1. 1. Download the workflow JSON

    Use the JSON export at /data/workflows/3871/3871.json as the source template for this automation.

  2. 2. Import the template into n8n

    Open n8n, import the downloaded JSON, and review each node before activating the workflow.

  3. 3. Configure credentials and variables

    Replace placeholder credentials, API keys, webhook URLs, account IDs, and environment-specific values with your own settings.

  4. 4. Test with sample data

    Run the workflow manually or in a staging workspace, inspect node output, and confirm downstream systems receive the expected data.

  5. 5. Activate and monitor

    Enable the workflow only after testing, then monitor executions, errors, and rate limits during the first production runs.

5. General Notes & Resources

Review imported nodes carefully before activation. This catalog entry is intended to help you inspect the workflow structure, understand required services, and find related templates faster.

Node names, credentials, schedules, webhook paths, and external service limits may need adjustment for your workspace.
