How to convert csv to JSON nested structure - json

Question

I have a json file to store my data and I convert it to CSV to edit my data. But when i convert it to json again it all goes unconstructed. How can i convert my csv to same structure as my old json.
JSON
{
"product": [
{
"id": "item0001",
"category": "12",
"name": "Name1",
"tag": "tag1",
"more": [
{
"id": "1",
"name": "AL"
},
{
"id": "1",
"name": "BS"
}
],
"active": true
},
{
"id": "item0002",
"categoryId": "13",
"name": "Name2",
"tag": "tag2",
"size": "2",
"more": [
{
"id": "2",
"name": "DL"
},
{
"id": "2",
"name": "AS"
}
],
"active": true
}
]
}
CSV
id,categoryId,name,shortcut,more/0/optionId,more/0/price,more/1/optionId,more/1/price,active,more/2/optionId,more/2/price,spanSize
item0001,ab92d2c6-010e-4182-844d-65050e746617,Name1,Shortcut1,1,60,1,70,TRUE,,,
item0002,ab92d2c6-010e-4182-844d-65050e746617,Name2,Shortcut2,2,60,2,70,TRUE,2,2,4

You can use Miller (mlr) to convert you file both ways
https://miller.readthedocs.io/en/latest/flatten-unflatten/
first from JSON to CSV
mlr --ijson --ocsv cat test.json > test.csv
then edit CSV (Visidata is a very nice command line tool for the job)
then convert it back to CSV
mlr --icsv --ojson cat test.csv > test_v2.json
If you want to have some JSON lines structure instead, use --ojonl
