Who is this workflow for? This workflow automates the removal of Personally Identifiable Information (PII) from CSV files stored in Google Drive. Leveraging n8n and OpenAI, it identifies and sanitizes sensitive data, ensuring compliance and data protection without manual intervention..

What does this workflow do?

  • Monitor Google Drive: The workflow activates when a new CSV file is uploaded to a specified Google Drive folder.
  • Identify PII Columns: The OpenAI node analyzes the CSV data to detect columns containing PII, such as names, emails, or phone numbers.
  • Remove PII: Identified PII columns are excluded from the dataset, effectively sanitizing the file.
  • Upload Cleaned File: The sanitized CSV is renamed and uploaded to a designated Google Drive folder, preserving the original file.

Customization Options

  • PII Identification: Tailor the OpenAI prompt to match specific data compliance requirements or to recognize additional PII types.
  • File Type Filtering: Configure the Google Drive Trigger to monitor specific file formats, such as limiting to CSV files only.
  • Output Destination: Specify different Google Drive folders for cleaned files to organize sanitized data effectively.
