About JSON to CSV Converter
This tool converts a JSON array of objects into a CSV (Comma-Separated Values) file. The first object's keys become the CSV headers, and each object becomes a row. The resulting CSV can be opened in Excel, Google Sheets, or any spreadsheet application.
Input Format
The input must be a JSON array of flat objects where each object shares the same keys. Nested objects or arrays in values will be serialized as JSON strings within the CSV cell.
FAQ
The tool uses the union of all keys across all objects as the CSV headers. Missing values for a given row are left as empty cells.
Values containing the delimiter character or double quotes are automatically wrapped in double quotes, and any internal double quotes are escaped as per the RFC 4180 CSV standard.
Deeply nested structures don't map naturally to flat CSV. Nested objects and arrays are stringified into a single cell. For best results, flatten your JSON before converting, or use JSON to XML for hierarchical output.
