DSPFD logical file "based on file" info to outfile

Command "DSPFD <LF file> TYPE(*ALL)" shows the based-on physical files. I need to get this info on all LF files into an outfile. TYPE(*ALL) isn't valid for an outfile. I haven't found any TYPE parameter that can be used with an outfile and that provides based-on physical files info.

SYSFILES has the information in the BASED_ON_FILES column, but it's provided as:
{"BASED_ON_FILES":[{"LIBRARY":"TESTLIB","FILE":"SAR7001P","MEMBER":"SAR7001P","LF_FORMAT":"RSAR7001"},{"LIBRARY":"TESTLIB","FILE":"CTYID","MEMBER":"CTYID","LF_FORMAT":"RSAR7001"}]}
I'd really rather not have to parse that out.

Any ideas?
