Frequently Asked Questions

Is my JSON data safe?+
Completely. All conversion happens locally in your browser using JavaScript. Your JSON is never sent to any server, logged, or stored anywhere.
What JSON formats are supported?+
Arrays of objects (most common API export format), including nested objects which are automatically flattened. Single objects are also supported as single-row CSV output.
How do I convert JSON to CSV for Google Sheets?+
Convert using Toolzoid, click Copy, then paste directly into Google Sheets cell A1. Sheets automatically detects the CSV format and splits into columns.
What if my JSON has inconsistent keys?+
Toolzoid collects all unique keys across every object and uses them as column headers. Missing values appear as blank cells — no data is lost.
