Why use this Data Formatter?
- Automatic validation. Invalid data triggers an error message first. The tool never shows a broken result.

- Two formats at once. JSON and XML, the two most common data formats, in a single tool.
How to format JSON or XML

- Paste your data in the input column.
- Watch the formatted result appear in the right column.
- Click Copy or Download to save it.
When you need this tool
An API response arrives as one long line. Checking it gets much easier once it's formatted.
A JSON or XML config file needs a validity check before your app uses it.
The minify feature shrinks a JSON file before you ship it to production, without changing the data.
Frequently asked questions
Does this tool validate my JSON/XML too?+–
Yes. Invalid data triggers an error message explaining the problem, and the tool never shows a broken result.
What's the difference between Format and Minify?+–
Format adds indentation so people can read it easily. Minify strips every space and line break to shrink the file, suited for production.
Is minify available for XML too?+–
Not yet. Minify currently works for JSON mode only. For XML, the tool focuses on indentation.
Is my data uploaded to a server?+–
No. Formatting and validation run in your browser from start to finish.
