Can I translate a stacktrace from minified code into a human readable stacktrace using sourcemaps?

I have some errors from minified code in production. I have sourcemaps not in production. I'd like to (after the fact) use source maps in a way to convert my stack trace into a human readable stack trace. Has anyone done this before?

Raygun developed a Source Maps Validator which let's you upload your source map file.

If you do that, then you can take the line number and column number from the stacktrace of your minified sourcecode to identify the original source which is causing the problem.

Example:

Stacktrace on production (in .min.js file)

Cannot read property 'split' of undefined at https://app.wire.com/min/wire-vendor.min.js?2016-06-06-15-36-prod:15:25804

Reading the stacktrace, the line number is 15 and the column number is 25804 (last two parts of the url).

Result:
