JSON to CSV Converter
Flatten structured JSON data into CSV for spreadsheets and analysis. Handles arrays of objects with a common schema.
Top-level keys become columns; arrays of objects produce one row per object.
All conversion happens locally in your browser using modern canvas APIs — files never leave your device.
