Frequently asked questions
What is JSON?
JSON (JavaScript Object Notation) is a lightweight format for exchanging structured data, widely used in web development APIs.
How does the tool validate my JSON?
The tool parses the string using standard JSON specifications. If it finds any syntax errors (like missing brackets or extra commas), it displays the exact error message and position.
Does minifying change JSON structure?
No. Minification only strips whitespace, line breaks, and tabs to reduce size for faster transmission, without changing data values.
