There's no export button in the Changelog dashboard. To get all your posts in one place — for an archive, a migration, or a review — retrieve them through the Beamer API and save the response yourself.
What isn't available
No CSV, JSON, or PDF export in the dashboard.
No bulk download of posts, images, or comments.
No multi-select on the Changelog dashboard, so you can't select posts and export the selection.
Retrieving your posts through the API
Beamer's API can return your posts, so you can save them in whatever format you need. Authenticate with an API key from Settings > API in your dashboard. See our API documentation for the endpoint, the full parameter list, how to page through large sets, and how to narrow results by post status.
The response is JSON, with one object per post. Each one includes the title, the content as both plain text and HTML, the publication date, the category, and a permalink to the post. Once you have the JSON you can convert it to a spreadsheet or a document with any standard tool.
Two things worth knowing before you start:
Every request counts against your monthly API allowance. A large Changelog exported in one pass can be a meaningful number of requests, so check your remaining allowance first under Settings > API. See Is there any limit for API requests?
Images aren't included in the export. Posts reference their images by URL. If you need the image files themselves, download them separately from those URLs.
