From George Smart's Wiki
This perl script was created to convert the EDI data from the RSGB contest page into ADIF format for use with programs such as Cloudlog. I wanted to be able to publish these results on my personal Cloudlog logbook as well as the club's logbook.
Eventually, this site will offer the ability to upload an EDI file and download an ADIF ADI file. For now, just the Perl script is offered.
I make no claims as to the standards it breaks/follows, but it works nicely with the RSGB data and into ADIF for Cloudlog.
