####JSON To CSV Converter
This code can be used for generating a flat CSV file from a list of JSON Objects. The JSONFlattener will create list of key-value pairs for the generated JSON. The CSVWriter would write the key value pairs to the specified file.
For example, consider the JSON format:
[
{
"studentName": "Foo",
"Age": "12",
"subjects": [
{
"name": "English",
"marks": "40"
},
{
"name": "History",
"marks": "50"
}
]
},
{
"studentName": "Bar",
"Age": "12",
"subjects": [
{
"name": "English",
"marks": "40"
},
{
"name": "History",
"marks": "50"
},
{
"name": "Science",
"marks": "40"
}
]
},
{
"studentName": "Baz",
"Age": "12",
"subjects": []
}
]would generate a CSV as below:
| Age | studentName | subjects1marks | subjects1name | subjects2marks | subjects2name | subjects3marks | subjects3name |
|---|---|---|---|---|---|---|---|
| 12 | Foo | 40 | English | 50 | History | ||
| 12 | Bar | 40 | English | 50 | History | 40 | Science |
| 12 | Baz |
The column names would dynamically be generated based on the keys in the JSON object.
