Hi, I want to create a table from the sample log file entry by computing the field names based on the entries defined in the JSON structure. There will be multiple filed names and not just one. e.g. in, the JSON structure, it has entries like "something":"value" "something" will be the field name, and "value" will be the value that will form the table entries. By working in https://regex101.com I have got the regex query that is doing the job. However, when I try to put that in the Splunk search query, it does not like the "]" in the regex query I have generated. This is the regex query: "((?:[^"\\\/\b\f\n\r\t]|\\u\d{4})*)" Query in Splunk | rex "((?:[^"\\\/\b\f\n\r\t]|\\u\d{4})*)" Error in Splunk : Error in 'SearchParser': Mismatched ']'. This is the sample log: ------------------- 2022/08/31 04:33:10.897 | server| service| INFO | 1-223 |x.x.x.x.x.Payload | xxx-1111-1111111-11-111111111 | AAt: Update Headers: {AAgid=ID:jaaana-11111-1111111111111-3:487:1:1:50, cccc_ff_ssss=ABC_XYZ, ssssdel=false, cdmode=1, DelMode=2, abc_corel_id=xyx-11111-11111-11-111111, aa_rrr_cccc_cccc=AAAA, cust_svc_id=AAAA-DDD, crumberid=xyx-11111-11111-11-111111, svc_tran_origin=SSS, SSScoreed=Camel-SSS-1111-1111111-111, cccc_ff_ssss_aaaaa=AAAA, AAAType=null, cccc_ff_ssss_tata=AAA, AAAexxxx=0, avronnnn=url.add.add.com, AAAssssssss=1661920390882,tang_dik_jagah=ABC_XYZ, ver=0.1.2, AAAprrrrrr=4, AAArptooo=null, source_DOT_adaptr=mom, AAAjaaana=tAAic://toic,tang_dik_jagah_tata=AAA, targCTService=progr, SSScoreedAsBytes=[a@123, CamelAAARequestTimeout=600000, sedaTimeout=600000} {[{"type":"AAtiongo","pAAo":"AAAA","ssssssss":"2022-08-31 00:00:00","data":[{"chabbbi":"ca_1111_11111_AAtiongo_AAAA","tatajahajqaki":"AA 111","jahajqaki":{"numeo":"111","jahaaj":{"cde":"ARL_AA","couAAa":"AA","aaoo":"AAR"},"AAsuf":null},"sgnnnn":"AAR111","stppp":"J","muddStatuscde":"AA","kissak":"III","AAType3lc":"111","AAType5lc":"B111","rggggggg":"AAAAA","carrrrr":{"cde":"ARL_AA","couAAa":"AA","aaoo":"AAR"},"ddddddcde":"pubbb","pubbbjahajqaki":"AA 111","jahajqakipubbb":{"numeo":"111","jahaaj":{"cde":"AA","couAAa":null,"aaoo":null}},"sssss":1098,"kkkkkss":834,"kitnaba":{"AAAAAA":"2022-08-2100:00:00","WWWW":"2022-08-2100:00:00","eeeeee":"2022-08-2100:00:00","sssssss":"2022-08-2100:00:00","ddddddd":"2022-08-2100:00:00","eeeeeeee":"2022-08-2100:00:00","ddddddddd":"2022-08-2100:00:00","ttttttt":"2022-08-2100:00:00","ttttttt":"2022-08-2100:00:00","Edddddd":"2022-08-2100:00:00","ffffff":"2022-08-2100:00:00","ddddddL":"2022-08-2100:00:00","dddddd":"2022-08-2100:00:00","Adddddd":"2022-08-2100:00:00","ssssT":"2022-08-2100:00:00","ddddd":"2022-08-2100:00:00","ggggg":"2022-08-2100:00:00","ffffff":"2022-08-2100:00:00","Eddddd":"2022-08-2100:00:00","ssssss":"2022-08-2100:00:00","Eddddd":"2022-08-2100:00:00"},"durdddd":{"Exxxxx":"Pdddd.oo","ScfffTTTT":"xxx1H0M0.000S","xxxxIDL":"-Pxxxx6M0.000S","ESTTTT":"PxxxxH26M0.000S"},"gallle":[{"aaaaaaa":"aaa000033","gffffnnnn":"111"}],"stsssss":[{"hhhhhh":"AA1111111","standnnnn":"S20"}],"blttttt":[{"hhhhhh":"ABB000003","beltnnnn":"aa11","beltAAenpttttt":"2022-08-2100:00:00","kkkkkkkpttttt":"2022-08-2100:00:00"}],"redddddd":{"SSSSS":[{"aalllll":"ALLUU99999","resssssss":"AA1111111","resssssssnnnn":"S20","pprrrrrsssss":"AAA11111"}],"bgggg_blt":[{"aalllll":"aaaaaa1111111","resssssss":"ABB000003","resssssssnnnn":"IB02","kitnaba":{"AAAAAA":"2022-08-31006:14:00a","AAAAAA":"2022-08-31006:14:00a"}}],"aaaaaaaaaaa_sss":[{"aalllll":"aaaaaa8888888","resssssss":"false"}],"aaaaaaaaaa_ssss":[{"aalllll":"aaaaaa8888888","resssssss":"GAT000033","resssssssnnnn":"120","pprrrrrsssss":"GAT000019"}],"qqqqqqqqqqqq":[{"aalllll":"qqqqqqqqqqqq","resssssss":"false"}]},"kkkkkk":[{"cde":"aaa_sss","tatAAde":"CAI","aaaaAAde":"PPPP","legnumeo":1},{"cde":"ABC_XYZ","tatAAde":"AAA","aaaaAAde":"AAAA","legnumeo":2}],"cdeshareList":[{"numeo":"1111","jahaaj":{"cde":"ARL_AA","couAAa":"AA","aaoo":"AAA"},"AAsuf":null,"pubbbjahajqaki":"AA 1111","jahajqakipubbb":{"numeo":"1111","jahaaj":{"cde":"AA","couAAa":null,"aaoo":null}}},{"numeo":"1111","jahaaj":{"cde":"ARL_CT","couAAa":"CT","aaoo":"CTH"},"AAsuf":null,"pubbbjahajqaki":"CT 1111","jahajqakipubbb":{"numeo":"1111","jahaaj":{"cde":"CT","couAAa":null,"aaoo":null}}}],"saaaaaa":{"ffff":"RRR","mapr":"Finalised","SSSGeneral":"AAened","AAceptance":"Finalised","loddacctrr":"SheCT_Finalised","brrrrrrdd":"AAened","IIIernal":"110"}}]}]} host = mucAAuplfrAA02 -----------------------
