About this tool
Paste a CSV with a header row. For every column the tool walks the values and reports the most likely .NET type (int, long, decimal, bool, DateTime, Guid, Uri, Email, TimeSpan or string), a format hint (e.g. `yyyy-MM-dd`, `1/0`, `percentage`), and a confidence percentage. Use it to scaffold typed schemas before importing CSV into a database or DTO.
