toolhq vs FreeFormatter: XML in the browser

FreeFormatter has been around for a long time, and it is genuinely useful. It collects a wide range of formatters, validators, and converters in one place: XML, JSON, HTML, SQL, XSLT transforms, encoders, and more. If you need an unusual conversion now and then, the breadth alone is a good reason to keep it bookmarked. This post compares it to toolhq with a narrow focus, XML formatting, and tries to be fair to both.

The job: making XML readable

Most XML formatting is the same task. You have a blob of XML on one line, or with inconsistent indentation, and you want it laid out with clean nesting so you can read it. A good formatter also tells you when the document is not well formed, pointing at the place where a tag is unclosed or mismatched.

Both tools do this. The difference is mostly in where the work happens and what surrounds it.

How they differ

The main distinction is architecture. toolhq runs its formatting in your browser: the XML you paste is parsed and reindented locally, and nothing is sent to a server. FreeFormatter is a broader site, and some of its operations are server side, which is a normal and reasonable design for a tool collection of that size. It is also ad supported, which is how it stays free.

| | toolhq XML Formatter | FreeFormatter | | --- | --- | --- | | XML formatting and validation | Yes | Yes | | Runs in the browser | Yes | Some operations server side | | Breadth of formats and converters | Focused (XML, JSON, more) | Very broad | | Ad scripts | None | Ad supported | | Signup required | No | No |

What each does well

FreeFormatter wins on range. If your week involves XSLT, an obscure encoder, or a converter between two formats you rarely touch, having all of it under one roof saves time. A long lived tool collection like that is a practical thing to have, and there is no need to talk it down.

toolhq is narrower by design. It does the common formatting jobs, XML and JSON, and does them with a quiet, fast interface and a clear privacy stance. Because the parsing is local, the XML you paste never leaves your machine, which matters when a document contains identifiers, customer data, or anything from an internal system. There are no ad scripts loading alongside your work, so the page stays fast and the layout stays still.

When privacy makes the choice for you

If the XML is a public sample or a config snippet you would happily post in a forum, either tool is fine. The decision gets easier when the content is sensitive:

A SOAP response containing real account data.
A configuration file with internal hostnames or endpoints.
Any export from a system your company would not want shared.

For those, a tool that formats locally is the safer default, simply because the data has nowhere to travel. This is not a knock on FreeFormatter, which is open about being a hosted service. It is the ordinary caution you apply to anything sensitive.

A practical pairing

In day to day work, the two can coexist. Keep FreeFormatter for the long tail of conversions you reach for a few times a year, and use a local tool for the everyday format and validate loop on data you would rather keep to yourself.

For fast, in browser XML formatting and validation, use the XML Formatter. If you are working with JSON in the same session, the JSON Formatter sits right beside it and behaves the same way, and the Diff Checker is handy when you need to compare two versions of a document. Pick the tool that fits the data in front of you, and when that data is sensitive, let it stay in your browser.
