For ARRL contesting logs consider supporting ALL cabrillo-formatted exported files for ALL the ARRL published contests in the correct cabrillo format for each of the contests. This is for the body of the cabrillo file not the header.
Here is an example 3 different ARRL contests RTTY, 10Ghz and up, Digi:
each of the formatted cabrillo files can have different information in the columns.
Exporting the contest log from WRL should export the contest cabrillo file in the proper format with the correct data in each of the columns suitable for uploading to the ARRL contest site. The published contests are listed at: ARRL Contest Calendar
