XML Formatter
Format & validate XML
XML Formatter: Format & validate XML. A free, browser-based tool from DevToolbox that runs entirely on your own device: no upload, no account, no tracking.
About the XML Formatter
Free online XML formatter and validator. Format, validate, and pretty print XML documents instantly in your browser. It is one of the beautifiers & formatters tools on DevToolbox, and like all of them it runs entirely in your browser.
Formatting happens by parsing your input into a structure and printing it back out with consistent indentation, so the result is the same document with different whitespace, never a rewrite of its meaning. Invalid input is reported with the position that broke the parse rather than silently repaired.
What you can do with it
- XML validator
- Format XML online
- XML pretty print
- XML beautifier
How to use it
- Paste or type your code into the input pane.
- The formatted result appears in the output pane as you type. There is no run button to press.
- If the input will not parse, the status bar turns red and names the problem and its position.
- Use Copy to put the formatted result on your clipboard.
Questions
- Is my data uploaded anywhere?
- No. The tool is JavaScript that runs in the tab you already have open, and DevToolbox has no backend to send anything to. You can open the network tab and watch: after the page and its script load, nothing is sent while you work.
- Does it work offline?
- Once the page has loaded, yes. The tool needs no network access to do its job, so it keeps working if your connection drops. Reloading the page does need the network unless your browser has it cached.
- Is it free, and do I need an account?
- It is free and there is no account, no sign-in and no usage limit. There is nothing to register because there is no server keeping track of anything.
