CSV PII Scanner
Audit every column for emails, phone numbers, SSNs, credit cards, and IP addresses — and get a redacted report without your data ever leaving the browser.
Audit every column for emails, phone numbers, SSNs, credit cards, and IP addresses — and get a redacted report without your data ever leaving the browser.
Load a CSV, run the scan, and read the report. The tool inspects every cell in every column, matches it against well-known PII patterns, and tells you exactly which columns leak which kind of sensitive data.
Drop in or paste any CSV file. Parsing happens locally in your browser — nothing is uploaded, and no server ever sees a single row.
Every column is tested cell-by-cell against patterns for email, phone, SSN, credit card (Luhn-validated), and IPv4 addresses. Credit-card and SSN checks use structural validation to cut false positives.
You get one row per column and PII type, with a match count and a safely redacted sample so you can confirm the finding without re-exposing the raw value.
Exports leak. A spreadsheet meant for analytics quietly carries customer emails, card numbers, or government IDs. Catch it before it leaves your control.
The entire scan runs client-side in JavaScript. Your raw rows are never transmitted, logged, or stored — the report is generated on your own machine.
Credit cards pass a Luhn checksum and length check; SSNs reject impossible area and group blocks. That means fewer false alarms than a naive regex sweep.
Instead of a vague yes/no, you see which specific columns contain which PII types and how many cells matched — so you know exactly what to drop, mask, or anonymize.
Samples in the report are redacted — partial emails, last-four digits, masked octets — so you can verify a finding without copying sensitive data into a ticket or chat.
