Ready when you are.

  1. Add a local file or paste data.
  2. Analyze format, quality, and likely sensitive fields.
  3. Review, clean, and export the in-tab working copy.
01 / Parse

Know the shape of the data.

Detect delimiters, validate structured text, and surface useful error locations.

02 / Review

Spot quality and privacy risks.

Measure completeness, duplicates, mixed values, and likely identifiers before sharing.

03 / Prepare

Clean a working copy locally.

Trim, deduplicate, mask, infer a schema, and export without changing the original file.

Practical guide

The seven-part data readiness check

Readiness is contextual, but the same failure modes appear repeatedly. Establish the dataset’s purpose and provenance, validate syntax, profile completeness, reconcile types, inspect duplicates, review privacy, and verify the exported artifact.

  • 01Write down the intended use, source, owner, and update date.
  • 02Validate structure and record counts before changing values.
  • 03Measure missingness and type consistency by column.
  • 04Review duplicates, sensitive fields, and the final export separately.
Does Parse The Data upload my files?

No. Parsing, profiling, cleanup, and export run inside your browser tab. The application does not send dataset contents to our server or any third party.

What file types are supported?

The first release supports CSV, TSV, JSON, and JSON Lines (JSONL or NDJSON), including pasted text and local files.

Can it detect every privacy risk?

No. The privacy scan uses deterministic patterns and column-name hints. It can find common emails, phone numbers, IP addresses, SSNs, and payment-card patterns, but it is not a substitute for a formal privacy review.

Designed for restraint

The server delivers the tool. It never receives the dataset.

Parsing runs in a separate browser thread. There are no accounts, upload endpoints, third-party scripts, advertising trackers, or cloud storage in the analysis path.

Use the PII scan as an early warning—not as legal advice or a compliance certification.
