What types of JSON does this tool support?

The tool supports JSON arrays of objects (the most common case for table data), single objects (displayed as a two-column key-value table), and arrays of primitives. Nested objects within cells are displayed as formatted JSON strings.

Is my JSON data sent to any server?

No. All processing happens entirely in your browser using JavaScript. Your JSON data never leaves your device — there are no servers involved.

Can I customize the HTML table styles?

Yes. You can toggle striped rows, table borders, compact padding, and choose a header background color. The generated HTML includes inline styles so it works anywhere without external CSS.

How do I use the generated HTML table?

Click 'Copy HTML' to copy the code, then paste it directly into any HTML file, CMS editor, or email template. You can also download it as a standalone .html file and open it in any browser.

Does the tool handle large JSON datasets?

Yes, the tool can handle large JSON arrays with many rows and columns. For very large datasets (10,000+ rows), rendering may take a moment, but the conversion itself is instantaneous.

What happens if my JSON is invalid?

The tool shows a clear error message pointing to the issue in your JSON. Fix the syntax error and the table will regenerate automatically as you type.
