Unstructured resume parser with Thordata Universal API + OpenAI GPT-4.1-mini

Who this is for

This workflow is designed for:

• Recruiters, Talent Intelligence Teams, and HR tech builders automating resume ingestion.
• Developers and data engineers building ATS (Applicant Tracking Systems) or CRM data pipelines.
• AI and automation enthusiasts looking to extract structured JSON data from unstructured resume sources (PDFs, DOCs, HTML, or LinkedIn-like URLs).

What problem this workflow solves

Resumes often arrive in different formats (PDF, DOCX, web profile, etc.) that are difficult to process automatically. Manually extracting fields like candidate name, contact info, skills, and experience wastes time and is prone to human error.

This workflow:

• Converts any unstructured resume into a structured JSON Resume format.
• Ensures the output aligns with the JSON Resume Schema.
• Saves the structured result to Google Sheets and local disk for easy tracking and integration with other tools.

What this workflow does

The workflow automates the entire resume parsing pipeline:

Step 1: Trigger

• Starts manually with an Execute Workflow button.

Step 2: Input Setup

• A Set Node defines the resume_url (e.g., a hosted resume link).

Step 3: Resume Content Extraction

• Sends the URL to Thordata Universal API, which retrieves the web content, cleans HTML/CSS, and extracts structured text and metadata.

Step 4: Convert HTML → Markdown

• Converts the HTML content into Markdown to prepare for AI model parsing.

Step 5: JSON Resume Builder (AI Extraction)

• Sends the Markdown to OpenAI GPT-4.1-mini, which extracts:

  • basics: name, email, phone, location
  • work: companies, roles, achievements
  • education: institutions, degrees, dates
  • skills, projects, certifications, languages, and more

• The output adheres to the JSON Resume Schema.

Step 6: Output Handling

• Saves the final structured resume:

  • Locally to disk
  • Appends to a Google Sheet for analytics or visualization.
