FAQ
Is my data uploaded?
No. Everything runs locally in your browser.
Can I share a link to my CSV?
Share URLs include settings only. Use downloads to share generated data.
Why can unique generation fail?
If the value space is too small (e.g., integer range), duplicates may be unavoidable.
How do I reuse a schema?
Download schema JSON, then import it later.
