Frequently asked questions
How do I format XML?
Paste XML or open a file — it is indented instantly. Choose 2 or 4 spaces, tabs or Minify, and copy or download the result.
Does it check if my XML is valid?
It checks that the XML is well-formed (properly nested and closed tags, quoted attributes, escaped characters) and shows the exact line and column of the first error.
Can I run XPath queries?
Yes — type an XPath such as //book[price > 10]/title and the matching nodes appear in the XPath tab.
Is mixed content kept?
Yes — elements that mix text and tags (like a paragraph with a bold word inside) are kept on one line so no spaces are added to the text.
Is my data uploaded?
No. Everything is processed by JavaScript in your browser — nothing you paste or open is sent to a server, so it is safe for API responses, tokens, configs and customer data. It also works offline once the page has loaded.
