Frequently Asked Questions

Can I convert large JSON files?

Yes! Our converter handles JSON files up to 5MB. All processing happens in your browser, so performance depends on your device. For very large files, we recommend using the Table or CSV view for better performance.

How do I export JSON to Excel?

After converting your JSON, click the "Export" dropdown and select "Excel". Your data will be downloaded as an .xlsx file with automatic column sizing and formatting. Nested objects are flattened, and arrays are joined with commas.

Does this work with nested JSON structures?

Absolutely! Use the Tree view for the best visualization of deeply nested JSON. The Table view flattens nested objects, while Tree view preserves the full hierarchy with collapsible nodes.

Can I use this for API testing?

Yes! Many developers use our tool to visualize API responses during testing. Paste the JSON response from your API call, and instantly see the data in table format. Great for debugging REST APIs, GraphQL responses, and webhooks.

What's the difference between CSV and Markdown export?

CSV export creates comma-separated values perfect for Excel, Google Sheets, and databases. Markdown export creates formatted tables for documentation, GitHub READMEs, and markdown editors. Choose based on where you'll use the data.
