How does the tool handle deeply nested JSON structures?

Nested objects and arrays are rendered with increasing indentation levels, similar to how a code editor displays JSON. Each nesting level is visually distinct, making it easy to trace the hierarchy. For very deep nesting, the tool uses word wrapping and page breaks to keep the output readable.

Can I convert minified JSON to a readable PDF?

Yes. The converter automatically pretty-prints minified JSON before rendering. Regardless of whether your input is a single line of minified JSON or already formatted, the output PDF will have proper indentation, line breaks, and syntax coloring.

What is the maximum JSON file size supported?

Since processing happens locally in your browser, the limit depends on your device's available memory. Most modern devices can handle JSON files of 50-100 MB without issues. For extremely large files, the tool paginates the output automatically.

Is this useful for documenting API responses?

Absolutely. Developers and QA teams commonly use this to create PDF records of API responses for documentation, bug reports, and compliance audits. The syntax coloring and hierarchical layout make the output much more readable than raw JSON text.
