Free CWR checker and CWR creator on royalti.io

Check a CWR 2.1 or 2.2 file, or build a CWR 2.2 file from a spreadsheet, free in your browser. Your file is never uploaded, and the engine is open source.

Finding out that a CWR file will be rejected usually happens after you submit it. Two free tools on our website let you check it first, or build a clean one.

  • CWR checker: open a CWR 2.1 or 2.2 file, browse every record by field, and see problems listed against cited CISAC rules, with the rule source for each.
  • CWR creator: fill in our spreadsheet template (.xlsx or .csv), and the page builds a CWR 2.2 file, checks it with the same rules, and lets you download it. It builds up to 25 works per file.
  • Both run in your browser. Your file is never uploaded.
  • The engine behind both is open source: @royalti/cwr on npm and Royalti-io/royalti-cwr on GitHub.

Try them at royalti.io/tools/cwr-checker and royalti.io/tools/cwr-creator.
