Frequently Asked Questions
What does "Format" do?
Formatting adds proper indentation and line breaks to make JSON human-readable. You can choose between 2-space, 4-space, or tab indentation.
What does "Minify" do?
Minifying removes all unnecessary whitespace, reducing the JSON size. This is useful for API requests or storage optimization.
How does validation work?
The validator parses your JSON and checks for syntax errors like missing brackets, invalid quotes, or trailing commas. It shows the exact error location if problems are found.
Is my data secure?
Yes! All processing happens in your browser. Your JSON data is never sent to any server.
