Frequently Asked Questions

Is my code safe when using these tools?
Yes. All processing happens in your browser. Your code is never sent to any server, making it safe for proprietary and sensitive code.
Can I handle large files?
Yes. Most tools handle files up to 10MB+ smoothly. JSON and text tools use efficient parsing that works well with large datasets.
Do you support syntax highlighting?
Yes. The JSON Formatter includes a color-coded tree view, and formatted output uses monospace fonts for readability.
