AI-powered CV extractor: Google Drive to Sheet with GPT-4 + Slack for recruiters

CV Extractor: Google Drive to Sheet + Slack Update for Recruiters

Watch the demo video below:

> This workflow automatically processes resumes (PDFs) uploaded or updated in a Google Drive folder. It extracts and structures the candidate’s information using AI, then updates or inserts the data into a Google Sheet, acting as a central talent database. Finally, it notifies the hiring team via Slack with a summary. Perfect for HR and TA teams, this automation eliminates the repetitive task of manually copying candidate details from CVs into spreadsheets, saving hours of admin work every week and keeping your hiring pipeline clean, fast, and up to date.

👤 Who’s it for

This workflow is designed for:

• Recruiters and HR coordinators who manage candidate profiles via Google Drive.
• Talent Acquisition teams who want to automate CV parsing, enrichment, and database updating.
• Companies or hiring agencies using spreadsheets for candidate tracking and CRM-like HR ops.

⚙️ How it works / What it does

This smart and fully automated workflow:

1. Monitors a Google Drive folder for any uploaded or updated resumes (PDFs).
2. Downloads and extracts resume content using PDF parsing.
3. Sends the raw text to GPT-4, which returns a structured profile (name, title, experience, skills, etc.).
4. Verifies the profile and transforms it into a clean, row-based format.
5. Upserts the candidate profile into a Google Sheet (insert or update by email).
6. Notifies the hiring team in Slack or email that a profile was added or updated.

This is a no-touch pipeline to keep your candidate data clean, current, and centralized.
