Remove PII from CSV Files (Automated Personal Information Masking for CSV Files)
This workflow automatically monitors a Google Drive folder for new CSV files, and once a new file is detected, it initiates the process. It utilizes OpenAI to intelligently identify personally identifiable information (PII) columns and automatically removes this sensitive data, generating a de-identified file and re-uploading it to the designated folder. The entire process is efficient, intelligent, and requires no manual intervention, effectively reducing the risk of data breaches, making it suitable for businesses and teams that need to process privacy data in bulk.

Remove PII from CSV Files (Automated Personal Information Masking for CSV Files)
Key Features and Highlights
This workflow automatically monitors a specified Google Drive folder and triggers the process whenever a new CSV file is created. It downloads the file, leverages OpenAI’s intelligent analysis to accurately identify columns containing Personally Identifiable Information (PII), then automatically removes these sensitive columns. The desensitized CSV file is subsequently uploaded back to a designated Google Drive folder. The entire process requires no manual intervention, enabling efficient, intelligent, and secure data masking.
Core Problem Addressed
How to quickly and accurately identify and remove fields containing personal privacy information during data sharing and processing to prevent data leakage risks and ensure data compliance. This solution is especially suitable for scenarios requiring batch processing of large volumes of CSV files with strict data privacy requirements.
Use Cases
- Enterprise data teams needing to regularly share customer or employee data while removing sensitive information.
- Data analysts who want to automatically cleanse PII from data before using third-party tools.
- Compliance departments monitoring and handling files containing sensitive information to ensure privacy regulation adherence.
- Automated office environments aiming to reduce manual operation risks and accelerate data processing efficiency.
Main Workflow Steps
- Google Drive Trigger: Real-time monitoring of newly created CSV files in the specified folder.
- Fetch Filename and Download File: Extract the filename and download the file content.
- Extract File Data: Parse the CSV content to prepare data for subsequent processing.
- OpenAI Analysis: Invoke the GPT-4 model to intelligently identify column names containing PII.
- Data Merging: Combine OpenAI’s identification results with the original data.
- Remove PII Columns (Code Processing): Delete the identified PII columns to generate desensitized data.
- Upload to Google Drive: Upload the desensitized CSV file to the designated folder with a “_PII_removed” suffix for easy identification.
