from custodian_labs import GuardianLayer

result = GuardianLayer().deidentify_file(
    "customers.csv",
    masking_type="transform",
    pii_entities=["PERSON", "EMAIL_ADDRESS", "PHONE_NUMBER"],
)
with open(result.filename or "deid_customers.csv", "wb") as f:
    f.write(result.content)

import { writeFile } from "node:fs/promises";
import { GuardianLayer } from "@custodianlabs/sdk";

const result = await new GuardianLayer().deidentifyFile("customers.csv", {
  maskingType: "transform",
  piiEntities: ["PERSON", "EMAIL_ADDRESS", "PHONE_NUMBER"],
});
await writeFile(result.filename ?? "deid_customers.csv", result.content);

Swap redact for ***** output. Omit pii_entities (or ["ALL"]) to process everything.
