Using JSON parse and error detection functions by @sln,
Find/Replace is possible to pare down the objects to just two keys jobID and exec
keys and values.

For more information on how these recursive functions work and more practical
examples, see https://stackoverflow.com/a/79785886/15577665

Should be a complete and valid JSON string.

(?:(?=(?&V_Obj)){(?=(?:(?&V_KeyVal)(?&Sep_Obj))*?\s*("jobID"\s*:\s*(?&V_Value)))(?=(?:(?&V_KeyVal)(?&Sep_Obj))*?\s*("exec"\s*:\s*(?&V_Value)))(?:(?&V_KeyVal)(?&Sep_Obj))+})(?(DEFINE)(?<Sep_Ary>\s*(?:,(?!\s*[}\]])|(?=\])))(?<Sep_Obj>\s*(?:,(?!\s*[}\]])|(?=})))(?<Str>(?>"[^\\"]*(?:\\[\s\S][^\\"]*)*"))(?<Numb>(?>[+-]?(?:\d+(?:\.\d*)?|\.\d+)(?:[eE][+-]?\d+)?|(?:[eE][+-]?\d+)))(?<V_KeyVal>(?>\s*(?&Str)\s*:\s*(?&V_Value)\s*))(?<V_Value>(?>(?&Numb)|(?>true|false|null)|(?&Str)|(?&V_Obj)|(?&V_Ary)))(?<V_Ary>\[(?>\s*(?&V_Value)(?&Sep_Ary))*\s*\])(?<V_Obj>{(?>(?&V_KeyVal)(?&Sep_Obj))*\s*}))

Replace: { $1, $2 }

Output:

{
  "2597401": [
    { "jobID": "2597401", "exec": "ft.D.64" },
    { "jobID": "2597401", "exec": "cg.C.64" },
    { "jobID": "2597401", "exec": "mg.D.64" },
    { "jobID": "2597401", "exec": "lu.D.64" }
  ]
}

      (?: (?&V_KeyVal) (?&Sep_Obj) )*?
      \s* 
      ( "jobID" \s* : \s* (?&V_Value) )   # (1), capture jobID and value
