How do i convert this json file to csv - json

Question

I have this JSON which I want to convert to CSV, I have to use online tools for converting it but its not converting in proper CSV format according to the JSON format , but my JSON format is not in one layer, here is what I'm saying
because after converting into proper CSV i have to add some data and want to convert back to JSON like the original but with additional data so I can upload it on firebase

Answer 1

I suppose the first layer in the JSON is the first header name. The second layer has the value from 1st header as key and the other headers/values as value. This format is probably called "Hashed CSV". The format is something like below in Typescript:
type HashedCsv = {
[header1: string]: {
[value1: string]: {
[otherHeader: string]: string
}
}
}
So, to convert to CSV and from CSV you just need to have this type above in mind.
Below is a code snippet in JavaScript to convert the JSON to CSV. You can test it here on StackOverflow by clicking Run code snippet or with even with NodeJS.
function jsonToCsv (/** #type {{[header1: string]: {[value1: string]: {[otherHeader: string]: string}}}} */ json) {
// The first layer is the first header name
const header1 = Object.keys(json)[0]
const values = json[header1]
// In the 2nd layer are the other header names
const otherHeaders = Object.keys(Object.values(values)[0])
const headers = [header1, ...otherHeaders]
/** #type {string[]} */
const csvValues = []
for (const [value1, otherValues] of Object.entries(values)) {
csvValues.push([
value1,
// Escape commas and quotes
...otherHeaders.map(header => /[,"]/g.test(otherValues[header])
? `"${otherValues[header].replaceAll('"', '""')}"`
: otherValues[header])
].join(','))
}
return [
headers.join(','),
...csvValues
].join('\n')
}
const json = loadJson()
const csv = jsonToCsv(json)
console.log(csv)
// Loads the JSON. It could be a file or from memory like below
function loadJson () {
return {
"Quotes": {
"q1": {
"title": "The unexamined life is not worth living – Socrates"
},
"q2": {
"title": "Whereof one cannot speak, thereof one must be silent – Ludwig Wittgenstein"
},
"q3": {
"title": "Entities should not be multiplied unnecessarily – William of Ockham"
},
"q4": {
"title": "The mind is furnished with ideas by experience alone – John Locke"
},
"q5": {
"title": "We are too weak to discover the truth by reason alone – St. Augustine"
},
"q6": {
"title": "Man is the measure of all things – Protagoras"
},
"q7": {
"title": "Everything that exists is born for no reason, carries on living through weakness, and dies by accident – Jean-Paul Sartre"
},
"q8": {
"title": "To do as one would be done by, and to love one's neighbor as oneself, constitute the ideal perfection of utilitarian morality – John Stuart Mill"
},
"q9": {
"title": "Good and evil, reward and punishment, are the only motives to a rational creature – John Locke"
}
}
}
}
PS: Notice that I've stripped the JSON a bit.

try this
var jObject = (JObject)JObject.Parse(json)["Quotes"];
var arr = jObject.Properties().Select(a => new { title = a.Name, text = a.Value["title"] }).Dump();
var sb = new StringBuilder();
foreach (var item in arr)
sb.Append("\"" + item.title + "\"" + "," + "\"" + item.text + "\"" + Environment.NewLine);
File.WriteAllText("quotes.csv", sb.ToString());
