Frequently Asked Questions

What HTML elements are supported?

All standard HTML elements are supported, including div, span, p, h1-h6, img, a, table, form elements, and more. The tool preserves the hierarchical structure of your HTML document in the JSON output.

How does the JSON structure work?

By default, the tool creates a hierarchical JSON structure where each HTML element becomes a JSON object with properties like "tag", "attributes", "children", and "text". You can also choose a flattened array format for simpler processing.

Is my data secure when using this converter?

Yes, absolutely! This tool processes all files locally in your browser. No data is uploaded to any server or transmitted over the internet. Your HTML content remains completely private and secure on your device.

Can I convert multiple HTML files at once?

Yes! You can select and convert multiple HTML files simultaneously. Each file will be processed individually and you'll get separate JSON files for each input file.

What conversion options are available?

You can choose to include or exclude element attributes, text content, whitespace, HTML comments, and select between hierarchical or flattened JSON structure. You can also enable pretty formatting for better readability.

Are there any file size limitations?

The tool can handle reasonably large HTML files, but very large files (over 50MB) might cause performance issues in your browser. For best results, consider breaking down very large HTML files into smaller chunks.
