Frequently Asked Questions (FAQ)
Q. What is JSON?
A. JSON (JavaScript Object Notation) is a lightweight text format widely used for data exchange. It structures data using key-value pairs and is commonly used in Web API responses and configuration files.
Q. Is my JSON data sent to a server?
A. No, all processing is done entirely in your browser. Your input data is never sent to any server.
Q. Can it handle large JSON files?
A. It can process data within the limits of your browser's memory. Very large JSON files (tens of MB or more) may cause the browser to slow down.
Q. Does it support JSON with comments (JSONC)?
A. No, this tool processes data based on the standard JSON specification and does not support JSONC. Comments in the input will result in a syntax error.
