Frequently Asked Questions

Is this free?

Yes. This remove null values tool is free to use.

Is my data uploaded?

No. Processing runs locally in your browser—your JSON is not uploaded to a server.

Can nested null values be removed?

Yes. This tool removes selected empty types recursively from nested objects and arrays.

Can I keep empty strings?

Yes. Toggle off “Empty strings” to keep them while removing other empty values.

Does order stay the same?

Yes. Key order is preserved when possible, but removing fields changes the overall shape by deleting empty values.

What if nothing is removed?

That means no values matched your selected rules. Try enabling more filters or verify the input contains null or empty values.

Does it work on mobile?

Yes. The cleaner is mobile-friendly with a one-tap Clean JSON action and smooth scroll to results.

Can I download cleaned JSON?

Yes. After cleaning, you can copy the output or download it as a .json file.
