Analysis canvas

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

Shape a working copy locally.

Filter, sort, select, rename, deduplicate by keys, validate schemas, and export without changing the original file.

Practical guide

A visible, reversible CSV filter

Filters are easy to get wrong when blanks, number-like text, or letter case are involved. This workspace makes the operator explicit, reports the resulting row count, and keeps each change undoable.

  • 01Choose a column and a text, blank, or numeric comparison.
  • 02Preview the retained rows before downloading anything.
  • 03Apply a stable ascending or descending sort with blanks last.
  • 04Undo the last operation or reset to the analyzed source.
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?

CSV, TSV, JSON, and JSON Lines (JSONL or NDJSON) are supported as pasted text or local files up to 10 MB. CSV files can also be decoded as UTF-8, UTF-16, or Windows-1252.

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 tools. Your dataset stays in the browser.

The app files arrive first. Parsing, profiling, and cleanup then happen in a browser worker on your device. The dataset has no upload path.

  • No accounts
  • No cloud storage
  • No third-party scripts

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