Build an AI CV Extractor: JSON Structured Output Workshop

By Dorian Laurenceau

📅 Last reviewed: April 24, 2026. Updated with April 2026 findings and community feedback.

Theory is useless without practice. In this hands-on workshop, you will build a complete CV/resume data extractor, from raw resume text to clean, validated JSON. This is the exact pattern used by HR tech companies processing thousands of applications daily.

The Workshop Goal

By the end of this workshop, you will have a prompt pipeline that:

  1. Takes raw CV/resume text as input
  2. Extracts structured candidate data into a predefined JSON schema
  3. Handles edge cases (missing data, ambiguous entries, multiple roles)
  4. Validates output and retries on failure

Step 1: Define Your Schema

Before writing any prompt, define the exact output structure you need.

Step 2: Build the Extraction Prompt

Step 3: Test with Real Examples

Step 4: Handle Edge Cases

Step 5: Validation and Retry

Limitations

  1. No cross-referencing, The extractor trusts what the CV says. It cannot verify employment claims.
  2. Layout dependent, Heavily formatted CVs (columns, tables, graphics) may lose structure when converted to text.
  3. Bias risk, AI may assign higher confidence to CVs that match patterns in its training data.
  4. Privacy, Always send CV data through secure, compliant channels. Never log PII in development.
