Frequently asked questions

Does it sort arrays too?
By default it sorts object keys and leaves array order intact (arrays are ordered data). Use the JSON Array Tools to sort array elements.
Why sort JSON keys?
Sorting keys produces a canonical order that makes diffs, version control, and code reviews far easier to read.
Is my data uploaded to a server?
No. Every tool on JSONPost runs entirely in your browser using JavaScript. Your JSON never leaves your device, so it is safe to use with private or sensitive data.
