Can it sort recursively?

Yes, toggle Recursive to sort keys at every nesting level.

Can it sort arrays of objects?

Yes, enable array sorting and provide a key to sort objects by, or leave it blank to sort primitive arrays directly.

What is natural sort order?

Natural sort compares embedded numbers numerically, so item2 comes before item10.

Is my data uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your input never leaves your device and nothing is logged or stored on our servers.

Does it work offline and on mobile?

Yes. Once the page has loaded it keeps working without a network connection, and the layout is responsive so it stays usable on phones and tablets.
