よくある質問
What is JSON?
JSON (JavaScript Object Notation) is a lightweight, text-based data interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language.
What does this JSON Validator do?
This tool checks your JSON data for syntax errors and formatting issues. It ensures the structure conforms to the JSON standard (RFC 8259), helping you debug data before using it in applications.
How do I use the validator?
Simply paste or type your JSON text into the input area and click the 'Validate' or 'Format' button. The tool will immediately report any errors found or display a beautified version of your data.
What are the common rules for valid JSON?
Keys must be strings enclosed in double quotes. Strings must use double quotes, not single quotes. Trailing commas are not allowed. Data types include objects, arrays, strings, numbers, booleans (true/false), and null.
Can I minify JSON using this tool?
Yes, many validators include a 'Minify' or 'Compact' feature that removes all unnecessary whitespace (spaces, newlines, tabs) to reduce the file size for production environments.
Is my data secure when using this tool?
This validator typically runs entirely in your browser using JavaScript. Your data is not sent to a server, ensuring sensitive information remains private on your local machine.
What is the difference between a JSON object and a JSON array?
A JSON object is an unordered collection of key/value pairs enclosed in curly braces { }. A JSON array is an ordered list of values enclosed in square brackets [ ]. An object acts like a dictionary, while an array acts like a list.
