Frequently Asked Questions

What's the difference between formatter and beautifier?
The formatter focuses on indentation. The beautifier adds syntax highlighting with color-coded keys, strings, numbers, booleans, and nulls.
Can I collapse sections?
Yes, objects and arrays can be collapsed/expanded in the tree view for easier navigation of large JSON.
Is there a size limit?
The tool handles JSON up to several megabytes, but very large files may be slow.
