Frequently Asked Questions
What does JSON minification do?
Minification removes all unnecessary whitespace (spaces, newlines, tabs) from JSON, producing the smallest valid representation. Optionally, you can also remove null and empty string values for even smaller output.
Is my data safe?
Yes. All processing happens locally in your browser. No data is sent to any server.
What is 'Remove null & empty strings'?
When enabled, the tool strips null values and empty strings from objects. Use with caution – this changes the structure and might not be suitable for all use cases.
