Frequently Asked Questions

How does this JSON to CSV converter work?

Paste or upload your JSON data, and the tool instantly flattens nested objects and arrays into clean CSV rows. Nested object properties become columns. Arrays are exploded into separate rows by default.

Can it handle deeply nested JSON?

Yes! The converter recursively processes any depth of nesting. Nested structures like categories → items → sizes will properly explode into rows with all parent context preserved.

Is my data secure?

Absolutely. All processing happens 100% in your browser using JavaScript. Your JSON data never leaves your device.
