Download a diagram from a Jira issue

To download a diagram from a Jira issue, open the issue and download the diagram's file from its attachments, the same way as any other attachment. Each diagram is stored as a file named after its title, with an extension for its type such as .mermaid, .drawio or .bpmn. The app has no separate export or PNG download button.

#Before you start

You can view the issue and its attachments.
Know the diagram's title. The attachment is named after it.

#Steps

Open the issue.
Go to the issue's attachments.
Find the file named after the diagram's title, with a diagram extension such as .mermaid or .drawio.
Download it.

#What happens next

You have the diagram's source, which opens in any tool that reads that format, for example draw.io for a .drawio file.
For a picture rather than the source, open the diagram in that tool and export it there, or bring it into Capable Diagrams for Confluence, which can export PNG and SVG.

#If it does not work

Two attachments share a name: see Two diagrams on an issue have the same name and are hard to tell apart.
More on why there is no export button: There is no way to download or export a diagram from the app.
