What is the difference between JSON beautify and minify?

Beautify adds indentation and line breaks for readability; minify removes extra whitespace to produce a single-line JSON payload, useful for APIs and logs. Both are available in this tool.

How large a JSON file can I process?

It depends on your browser and device memory. A few megabytes usually work well; for very large files, consider splitting the payload or processing locally.

Can I use tree view and text view together?

After formatting, expand or collapse nodes in the tree to inspect fields while the source panel still shows the full JSON string.

Can minified JSON be beautified again?

Yes. Minify only removes whitespace; the data is unchanged. Click beautify anytime to restore indented formatting.

Does it handle Unicode and escape sequences?

Standard escapes such as \n and \uXXXX are supported. Syntax errors show an approximate location to fix bad API payloads.
