Changelog JSON Generator
What Is a Changelog JSON Generator?
A structured changelog JSON file lets a "What's New" widget, release-notes page, or in-app update feed render your release history consistently, instead of parsing free-form text every time. This tool turns a plain title and description into properly-formatted JSON with an auto-generated ISO date — ready to drop into a changelog feed.
Type your update title and description, and get valid, consistently-formatted JSON instantly.

Writing Changelogs Users Actually Read
1. Lead with the user impact, not the implementation
"Faster search results" reads better than "optimized search index queries" — describe what changed for the user, not the internal technical detail.
2. Group by type when you have several changes
Separating "New," "Fixed," and "Improved" in a single release entry makes a changelog far easier to scan than one flat paragraph.
3. Consistent structure matters more than length
A short, consistently-formatted entry that a widget can reliably parse is more useful than a long, free-form one that breaks your changelog display.
