Frequently Asked Questions
Answers to users' most common concerns
Common Questions
What is JSON format?
Expert Answer
JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It's based on JavaScript language standards but is language-independent, widely used for data transmission in web applications.
Common Questions
Why format JSON?
Expert Answer
Formatting JSON improves code readability and makes debugging and maintenance easier. While compressed JSON saves space, it's difficult to read; formatted JSON with proper indentation and line breaks makes it easier to understand data structure.
Common Questions
Is the AI repair feature safe?
Expert Answer
Yes, the AI repair feature runs entirely locally in your browser and doesn't send any data to external servers. We use advanced local algorithms to identify and fix common JSON format errors.
Common Questions
What file sizes are supported?
Expert Answer
The tool can handle most common JSON file sizes. For particularly large files (over 10MB), we recommend processing in chunks for better performance. The tool will show progress indicators when processing large files.
Common Questions
Does key sorting affect data?
Expert Answer
Key sorting doesn't change JSON data content, it only rearranges the order of object keys. This helps compare different JSON files and standardize data format, but may affect special applications that depend on key order.
Common Questions
Which browsers are supported?
Expert Answer
The tool supports all modern browsers including Chrome, Firefox, Safari, Edge, etc. We recommend using the latest browser versions for the best experience and performance.
