FAQs
What is the difference between formatting and beautifying?
While the terms are used interchangeably, "beautifying" often implies a greater focus on visual hierarchy and readability for human review.
Does this beautifier support JSON5 or YAML?
Currently, we focus on standard JSON (RFC 8259). We are working on expanding support to other data serializations soon.
Can I beautify JSON from a URL?
For security reasons, we currently only support direct paste. This ensures you are fully in control of what data is being processed locally.
Is there a "Dark Mode" for the beautified output?
Yes! Our interface respects your system preferences and provides a high-contrast dark mode for late-night debugging.
Will beautifying change my data values?
Absolutely not. Our engine only modifies whitespace and indentation; the underlying data integrity is preserved 100%.
