Quick Chart Maker

Type or paste data and export a chart — bar, line, pie, doughnut or scatter. Edit as a table or raw CSV/TSV, then download a PNG.

CSV Explorer

Open a CSV without a spreadsheet: sort, filter, per-column stats and histograms — then clean it up and re-export.

CSV ↔ JSON Converter

Convert between CSV and JSON in either direction with live preview, delimiter auto-detect, type detection and nested-JSON flattening.

Data Generator

Set up your columns and generate realistic fake data — names, emails, dates, prices and more — then export as CSV or JSON. Same seed = same data every time.

Data Anonymizer

Mask or fake-replace sensitive CSV columns — shuffle, hash, redact, add noise — with reproducible seeding and a k-anonymity check.
