Make Your JSON Readable Instantly

DiyoVM JSON Formatter converts complex, single-line JSON data into a human-readable, colorful, and hierarchical structure.

Missing a bracket or comma? Our tool instantly detects the error line and alerts you.

Keys, strings, and numbers are highlighted in different colors, improving code readability.

This tool works Client-Side. Your private API data is never sent to our servers; it is processed in your browser.

What is Minify?

Minifying removes all unnecessary whitespace and newlines from JSON. This reduces file size and speeds up data transfer.

Is there a file size limit?

Since processing happens in your browser, there is no strict limit. However, very large files (>50MB) may slow down your browser.
