Frequently asked questions

How are nested objects handled?
Nested objects are flattened into UPPER_SNAKE_CASE keys joined by underscores so they fit the flat .env format.
Can it convert .env back to JSON?
Yes. Paste .env content and switch direction to rebuild a JSON object.
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.
