Frequently asked questions

Can I sort by a nested field?
Yes. Provide a dotted path like user.age to sort or filter by nested values.
How does dedupe work?
Duplicate objects (by full value or a chosen key) are removed, keeping the first occurrence.
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.
