Frequently Asked Questions
Can I convert nested JSON to CSV? ▾
Toolpilot flattens nested JSON objects using dot notation (e.g., user.name becomes a column). For deeply nested structures, consider flattening with jq first.
Is there a file size limit? ▾
Toolpilot processes JSON in your browser, so the limit depends on your device's memory. Files up to several MB work smoothly.
Can I convert CSV back to JSON? ▾
Toolpilot currently converts JSON to CSV one-way. For reverse conversion, use ConvertCSV.com or write a quick script.
