Test Data Generator
Build a realistic test table in your browser: pick the columns and their types, set the row count and a seed, then export CSV or Excel. Nothing is uploaded.
Fake but safe: emails use example.com/.net/.org and phone numbers use the 555 range — never a real person.
Set up the columns on the left, then generate a table.
How it works
- 1.Import an Excel, CSV, TSV or JSON file, or paste the table. It is parsed on your own device.
- 2.Pick the columns to show: one category axis and up to three values.
- 3.Generate once, then keep tweaking — chart type, aggregation, sorting and theme update instantly.
- 4.Download an image, or publish the result as an encrypted link that expires on its own.
