What it does

Paste compact XML from an API response or configuration file and get an indented, line-by-line version. Attributes and self-closing tags are preserved as written.

Indent and format XML with a readable tree structure.

How to use it

Here is the short version of using XML Formatter.

  • Paste the XML — Fragments and full documents both work.
  • Read the formatted tree — Nested elements are indented by two spaces.
  • Copy the result — The output is plain XML, not a validated document.

Features that matter

What XML Formatter does well.

  • Nothing leaves your device — The work happens in your browser tab. There is no upload endpoint in this app, so your files and text cannot be stored, logged or seen by us.
  • No upload wait — You skip the round trip to a server entirely. Results are limited by your own CPU, not by network speed or queue size.
  • Free, no account, no quotas — No sign-up wall, no watermark, no daily limit. Optional accounts only exist to save favourites and presets across devices.

Frequently asked questions

Is my XML safe to use here?

Yes. This tool runs entirely in your browser using JavaScript. Nothing you paste or open is sent to a server, and the page keeps no copy after you close it.

Do I need to create an account?

No. Every tool is fully usable without signing in. An account only adds saved favourites and reusable presets.

Does it work on a phone?

Yes. The interface is mobile-first with large touch targets and a stacked layout, so it works on phones and tablets as well as desktops.

Does this validate XML?

No. It only adds indentation. Malformed XML may still be formatted but will not parse in an XML parser.

How are mixed text and child elements handled?

Text nodes are placed on their own lines for readability. That is a formatting choice, not a semantic change.
