How JSON is converted to CSV
- Each object in the array becomes one row.
- Columns are the union of all keys, so objects with missing fields get empty cells.
- Nested objects are flattened:
{"address": {"city": "Lahore"}}becomes the columnaddress.city. - Arrays inside objects are stored as JSON text in one cell.
Values that contain the separator, quotes or line breaks are quoted correctly, so the file opens cleanly in any spreadsheet app.
