How to use

Select Load example to restore the sample, or replace the labeled inputs with your own values.
Review the options and select Run tool. No input is sent to a server.
Message lines stay at the top. V8 at-lines and Firefox function@source:line:column lines are treated as frames.
Inspect the result, then copy or download it. Clear removes visible inputs and output.

Scope & limitations

Text organization only; no source-map resolution or execution. Unrecognized frame formats remain message lines. Duplicate comparison trims surrounding whitespace.
