### Configuration sample:
Add in [config.json]:
```json
{
"id": "json2csv_default",
"type": "@runnerty-executor-json2csv"
}
```
### Plan sample:
Add in [plan.json]:
#### JSON Example
```json
[
{
"planet": "Earth",
"radius": 6371,
"satellites": [
{
"name": "moon",
"radius": 1737
}
]
},
{
"planet": "Mars",
"radius": 3389,
