Uploading Files And Avoiding PII

Use the upload workflow safely, understand file constraints, and avoid publishing personally identifiable information.

File upload is one of the highest-risk workflows in the platform because it can expose sensitive or badly formatted data quickly.

The portal includes guardrails, but publishers still need to review content before upload.

Use Supported File Types

The upload field is intentionally filtered to common supported formats such as CSV, JSON, PDF, and Excel files.

CSV and JSON receive automated PII scanning. Other formats may still require manual review even if they upload successfully.

Respond To Upload Warnings

If the platform detects possible personal data in a CSV or JSON file, it interrupts the upload and requires the uploader to review the findings first.

The safest action is to cancel, clean the file, and upload again.

Watch out: Do not treat a successful upload as proof that a file is free of personal data. Unsupported file types are not deeply scanned.
