Frequently Asked Questions

How do I convert JSON to CSV?

Simply drag and drop your JSON file onto the upload area (or click to select it). ParseWiz will automatically detect the format, show you a preview, and let you download as CSV with one click.

What if my JSON file has errors?

Unlike other converters that just show "Parse Error", ParseWiz opens an inline editor showing exactly where the error is. Fix it directly in your browser and retry - no need to open another tool.

Can I convert nested or complex JSON?

Yes! ParseWiz detects complex structures automatically and offers two export options: split into multiple linked tables (with automatic record IDs for easy joining) or keep everything in a single compact row.

Is my data safe?

Your files are uploaded securely for processing and immediately discarded after conversion. We never store your data on disk or share it with third parties.

What file formats are supported?

ParseWiz supports JSON, CSV, and Excel files (.xlsx, .xls). You can convert between any of these formats freely. CSV delimiters (comma, semicolon, tab) are auto-detected.
