When to use this JSON to CSV converter

Use this converter when a JSON export needs to be reviewed in a spreadsheet or shared with someone who prefers table data. It is designed for everyday web, data, and developer workflows where a quick browser-side result is more convenient than opening a heavy desktop application.

The best workflow is to paste a small representative sample first, confirm the output looks correct, and then process the full content if it is appropriate to handle in your browser.
