Answer 1

Does this work making it easy for you to filter for things?

you can use Object.keys to find the corresponding message

const json = {
 data: [{
 identifier: 'A',
 itemType: 'Printer',
 error: [
 {
 'A0010': 'Not printing'
 },
 {
 'A0020': 'Out of ink'
 },
 {
 'A0030': 'No power',
 },
 {
 'A0040': 'Noise',
 },
 {
 'A0300': 'Feedback',
 },
 {
 'A0500': 'Other'
 }
 ]
 },
 {
 identifier: 'B',
 itemType: 'PC Issues',
 error: [
 {
 'B0010': 'No power'
 },
 {
 'B0020': 'BSOD',
 },
 {
 'B0030': 'Virus related'
 }, {
 'B0300': 'Feedback'
 },
 {
 'B0500': 'Other'
 },
 ]
 }
 ]
}

I'm not totally sure what you mean by identifier unless you mean via javascript 👇

var a = {
 "Printer":[ 
 {
 "identifier" : "A0010",
 "reason" : "Not printing"
 }, 
 {
 "identifier" : "A0020",
 "reason" : "Out of ink"
 },
 {
 "identifier" : "A0030",
 "reason" : "No power"
 },
 {
 "identifier" : "A0040",
 "reason" : "Noise"
 },
 {
 "identifier" : "A0300",
 "reason" : "Feedback"
 },
 {
 "identifier" : "A0500",
 "reason" : "Other"
 }]
}
var b = {
 "PC Issues":[ 
 {
 "identifier" : "B0010",
 "reason" : "No power"
 }, 
 {
 "identifier" : "B0020",
 "reason" : "BSOD"
 },
 {
 "identifier" : "B0030",
 "reason" : "Virus related"
 },
 {
 "identifier" : "B0300",
 "reason" : "Feedback"
 },
 {
 "identifier" : "B0500",
 "reason" : "Other"
 }]
}
