JSON to CSV

JSON and CSV are the two most common data interchange formats, but they serve different audiences. JSON is structured, supports nesting, and is native to APIs and JavaScript. CSV is flat, tabular, and opens directly in Excel, Google Sheets, and database import tools.

Converting JSON to CSV is essential when you need to share API data with non-technical stakeholders, import records into a spreadsheet or database, generate reports from JSON-based data sources, or migrate data between systems that expect different formats.

The main challenge is flattening nested objects. A JSON field like {"address": {"city": "NYC"}} needs to become a flat column — either address.city or stringified. Arrays within objects are typically joined or stringified. This tool handles both cases and properly escapes CSV values that contain commas, quotes, or newlines.
