What does the XML & HTML formatter do?

It reorganizes raw XML or HTML code, applying indentation by nesting level and color syntax highlighting. It can also minify, removing spaces and line breaks to make the file more compact.

Is it good for invoices and API responses?

Yes. It's ideal for viewing invoice XML, SOAP responses and legacy API returns, which often come on a single line. The tool indents and colors the content to make reading and debugging easier.

Does it work with messy HTML?

Yes. In HTML mode (or automatic), void elements like br, img and input are handled correctly, and the content of script, style, pre and textarea is preserved without reformatting.

How does minification work?

When you choose Minify, the tool removes line breaks and unnecessary spaces between tags and drops comments, producing the smallest possible file on a single line.

Is my code sent to any server?

No. All formatting happens locally in your browser via JavaScript. No XML, HTML or data is sent to ToolboxHub servers — safe even for invoices and sensitive data.
