About This Tool
JSON to CSV Converter takes a JSON array of objects and outputs a comma-separated values file with the object keys as column headers. It is the quickest way to get API response data into Excel, Google Sheets, or a data analysis tool without writing a script.
Most data work happens in spreadsheets, but data increasingly arrives as JSON from APIs. This bridge eliminates the manual copy-paste or custom script that would otherwise be needed.
Tip: The tool expects a flat array of objects — deeply nested JSON will not produce meaningful columns. Flatten nested fields first if your data has sub-objects you want as separate columns.
