Visual Common Works Registration Validator

This tool validates CWR files and outputs results as coloured HTML with additional mouse-over information on all fields.

It was released in 2017, sparking the revolution of independent CWR-capable tools. And sustained it since.

This YouTube video playlist describes this tool in more detail.

The yearly subscription for the full tool is €500 per user for the version that only supports CWR version 2.1 (the only one in real use) and $750 for the one that also validates CWR versions 2.2, 3.0 and soon 3.1.

Free (demo) version below only validates and highlights the first transaction, and only accepts CWR 2.1 files.
