Frequently Asked Questions
The JSON must be an array of objects where each object has the same keys. For example: [{"name": "Alice", "age": 30}, {"name": "Bob", "age": 25}]. The keys become the CSV column headers automatically.
Nested JSON (objects within objects) is flattened into a single row. Complex nested arrays may not convert perfectly — for best results, flatten your JSON before converting or use a dedicated ETL tool for complex data structures.
In Excel: go to File → Open, select the downloaded .csv file, and Excel will import it automatically. In Google Sheets: go to File → Import, upload the .csv file, and choose 'Comma' as the separator.
