Help & FAQ
Find answers to common questions and learn how to get the most out of our developer tools.
🚀Getting Started
Is my data safe when using these tools?
Yes, absolutely! All processing happens directly in your browser. Your data never leaves your device or gets sent to our servers. Everything is processed client-side for maximum privacy and security.
What file size limits do you have?
We support files up to 10MB, but we recommend keeping files under 5MB for the best performance. Large files may take longer to process and could affect browser responsiveness.
Which browsers are supported?
Our tools work on all modern browsers: Chrome 70+, Firefox 65+, Safari 12+, and Edge 79+. We recommend using the latest version of your preferred browser for the best experience.
Do I need to create an account?
No account required! All tools are completely free and work without registration. Your preferences are saved locally in your browser.
🛠️Using the Tools
How do I format JSON?
Paste your JSON in the input area and click "Format" or press Ctrl+Enter. The tool will beautify your JSON with proper indentation and formatting.
Can I upload files?
Yes! You can drag and drop files directly onto the input area, or click the upload button. We support .json, .txt, and other text-based files containing JSON data.
How do I save my work?
Your work is automatically saved in your browser and persists between sessions. You can also download the formatted result as a file using the download button or Ctrl+S.
What's the difference between Format and Minify?
Format beautifies your JSON with proper indentation and line breaks for readability. Minify removes all unnecessary whitespace to reduce file size, ideal for production use.

🔧Troubleshooting
Why is my JSON showing errors?
Common JSON syntax errors include:
- Missing or extra quotes around property names
- Trailing commas after the last property
- Unmatched brackets or braces
- Using single quotes instead of double quotes
Check the error message for the specific line and character position.
The tool is loading slowly. What should I do?
Try these steps: Check your internet connection, clear your browser cache, refresh the page, or try using a different browser. Large files may also cause slower performance.
Can I process very large JSON files?
Yes, but files over 5MB may affect browser performance. For very large files, consider breaking them into smaller chunks or using a desktop JSON editor for better performance.
My formatted JSON looks different. Is this normal?
Yes! We only change formatting (indentation, line breaks) but never modify the actual data structure or values. Your JSON data remains exactly the same, just more readable.
⚡Advanced Features
What encoding formats do you support?
We support Base64 encoding/decoding, URL encoding/decoding, and various text transformations. All encoding happens locally in your browser.
Can I validate JSON against a schema?
Currently, we provide basic JSON syntax validation. JSON Schema validation is on our development roadmap and will be available in a future update.
Do you support other data formats?
Yes! We're expanding our tools to include XML formatting, YAML conversion, and other developer-friendly formats. Check our tools page for the latest additions.
