This tool turns a flat JSON array of objects into a CSV table while quoting fields that contain commas, quotes, or line breaks.
Designed for: Developers and analysts exporting flat API results to spreadsheet-friendly text.
How to use this tool
Paste an array such as [{"name":"Ada","role":"editor"}]. The converter collects object keys, writes a header row, and escapes each cell according to CSV quoting rules.
How the result is produced
The browser parses JSON, collects the union of top-level object keys, converts primitive values to text, and doubles embedded quote characters inside quoted cells.
Test examples
An array of two records with name and role keys becomes a header row followed by two CSV records. An object value or nested array is serialized as JSON text inside one CSV cell.
Limitations
The output is designed for flat arrays of records. Nested objects, inconsistent schemas, very large arrays, and spreadsheet formula interpretation require additional review. The tool does not preserve a database schema.
Privacy and processing
The conversion is performed in the browser. The JSON is not sent to a server by the tool.
