Frequently asked questions

Are dotted keys nested?
Yes. Keys like app.server.port become nested JSON objects, and nesting is flattened back on reverse conversion.
Are comments handled?
Lines starting with # or ! are treated as comments and ignored during conversion.
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.
