What Can the Changelog Parser Do?
The Changelog Parser is a free online tool for developers that parses Keep a Changelog-format Markdown files, automatically extracting version numbers, release dates, and change records by category (Added/Changed/Fixed/Security, etc.). Parsed results can be exported as JSON for integration into automated release workflows.
Core Features
- Version Extraction: Auto-detect version numbers and release dates
- Change Categorization: Sort by Added/Changed/Deprecated/Removed/Fixed/Security
- Version Filtering: Dropdown to view changes for a specific version
- JSON Export: One-click export of structured JSON data
- Drag & Drop Import: Drag CHANGELOG.md files directly
- Statistics Overview: Version count, total changes, per-type breakdown
How to Use
1. Paste Changelog Markdown content in the input area, or drag a CHANGELOG.md file
2. Click "Parse" or use Ctrl+Enter shortcut
3. View parsed results: version list, change statistics
4. Use the version filter to view changes for a specific version
5. Click "Copy JSON" or "Download JSON" to export structured data
Use Cases
Case 1: Release Automation
In CI/CD pipelines, auto-parse CHANGELOG.md to extract the latest version's changes and generate GitHub Release Notes or Slack notifications.
Case 2: Documentation Generation
Auto-generate API documentation version history from Changelogs, keeping docs in sync with code changes.
Case 3: Change Audit
Project managers quickly understand the scope and type of changes across versions, assessing release risk.
Case 4: Data Migration
Convert Markdown Changelogs to JSON for import into databases or project management tools for further analysis.
Extended Knowledge
Keep a Changelog is a widely-adopted community standard defining 8 change types: Added (new features), Changed (modifications), Deprecated (soon-to-be-removed), Removed (deleted features), Fixed (bug fixes), Security (vulnerability patches), Unreleased (pending). Good changelogs are user-facing, explaining "why" not "how". Semantic Versioning (SemVer) pairs with Changelogs: MAJOR.MINOR.PATCH maps to Breaking/Feature/Fix.
