If the XML Formatter is not quite right for your workflow, these are the alternatives worth considering - what each one does well, where it falls short, and the situation it suits best.
What to Look for in Any Alternative
- Speed to a usable first result on your real tasks, not demo tasks.
- Control over the output: can you steer structure, length and tone?
- Cost against your actual volume, including the free tier you can live on.
- Privacy: what happens to what you paste, and for how long.
- Fit with the tools you already use every day.
The Alternatives
1. xmllint
Command line formatting and validation together.
Choose it when the task is occasional, the material is sensitive, or you specifically want a human or a different kind of tool in the loop. The trade-off is always the same one: more control or more speed, rarely both at once.
2. IDE XML support
Formatting inside editors that understand XML.
Choose it when the task is occasional, the material is sensitive, or you specifically want a human or a different kind of tool in the loop. The trade-off is always the same one: more control or more speed, rarely both at once.
3. Our code syntax highlighter
Colour tags and attributes for review.
Choose it when the task is occasional, the material is sensitive, or you specifically want a human or a different kind of tool in the loop. The trade-off is always the same one: more control or more speed, rarely both at once.
4. Our code compare tool
Diff two versions of the same document.
Choose it when the task is occasional, the material is sensitive, or you specifically want a human or a different kind of tool in the loop. The trade-off is always the same one: more control or more speed, rarely both at once.
5. Our YAML validator
Check the sibling config format as well.
Choose it when the task is occasional, the material is sensitive, or you specifically want a human or a different kind of tool in the loop. The trade-off is always the same one: more control or more speed, rarely both at once.
How to Decide
- Write down the one task you need this to handle every week.
- Try your real material in the {$n} and in one alternative.
- Compare edit time, not generation time - the shorter total wins.
- Re-check the decision in a month; habits and pricing both change.
The Option Nobody Mentions
Keep the XML Formatter and add a second step. Most apparent alternatives only do a different part of the same job - one produces, another checks, a third formats. Combining two focused tools with a short review in between often beats hunting for a single tool that does everything.
Frequently Asked Questions
Does formatting change the document data?
No - indentation and attribute order are cosmetic, so the elements and values stay identical.
Can it fix broken XML?
No - it formats well-formed markup, so missing tags must be repaired before formatting.
What happens to the declaration and comments?
They are preserved and kept in place at the top of the document.
Is my document stored?
No - formatting runs entirely in your browser.
