I'm not a big fan of (mis)using actual data as JSON key. If you have any influence over your developers, ask them to design a proper data structure. To rescue data in its current state, Splunk will need to construct a proper structure. For this purpose, json_set that Splunk added in 8.0 comes handy. Like this: (Because you didn't enclose sample data, I just assume that lint-info is a top key in your raw data.) | spath path=lint-info.-Wunused-but-set-variable{}
| spath path=lint-info.-Wunused-genvar{}
| mvexpand lint-info.-Wunused-but-set-variable{}
| mvexpand lint-info.-Wunused-genvar{}
| rename lint-info.*{} AS *
| foreach -Wunused-*
[eval -Wunused = mvappend('-Wunused', json_set('<<FIELD>>', "type", "<<FIELD>>"))]
| mvexpand -Wunused
| spath input=-Wunused
| fields - -Wunused-* _* This is the result from your sample: -Wunused location.column location.filename location.line source type warning {"location":{"column":58,"filename":"ab1","line":237},"source":"logic [MSGG_RX_CNT-1:0][MSGG_RX_CNT_MAXWIDTH+2:0] msgg_max_unrsrvd_temp; // temp value including carry out","warning":"variable 'msgg_max_unrsrvd_temp' is assigned but its value is never used","type":"-Wunused-but-set-variable"} 58 ab1 237 logic [MSGG_RX_CNT-1:0][MSGG_RX_CNT_MAXWIDTH+2:0] msgg_max_unrsrvd_temp; // temp value including carry out -Wunused-but-set-variable variable 'msgg_max_unrsrvd_temp' is assigned but its value is never used {"location":{"column":11,"filename":"ab3","line":328},"source":"genvar nn,oo;","warning":"unused genvar 'oo'","type":"-Wunused-genvar"} 11 ab3 328 genvar nn,oo; -Wunused-genvar unused genvar 'oo' {"location":{"column":58,"filename":"ab2","line":254},"source":"logic msgg_avail_cnt_err; // Available Counter update error detected","warning":"variable 'msgg_avail_cnt_err' is assigned but its value is never used","type":"-Wunused-but-set-variable"} 58 ab2 254 logic msgg_avail_cnt_err; // Available Counter update error detected -Wunused-but-set-variable variable 'msgg_avail_cnt_err' is assigned but its value is never used {"location":{"column":11,"filename":"ab3","line":328},"source":"genvar nn,oo;","warning":"unused genvar 'oo'","type":"-Wunused-genvar"} 11 ab3 328 genvar nn,oo; -Wunused-genvar unused genvar 'oo' Here is data emulation that you can play with and compare with real data | makeresults
