The Blocks in your workspace can be retrieved as a string via Blockly.Xml.domToText (Blockly.Xml.workspaceToDom( Blockly.getMainWorkspace() ) ). Then you can do whatever file download/upload mechanism you choose.

Excellent, tyvm!

My suggestion is to avoid using Blockly.getMainWorkspace() wherever possible.  Many applications have more than one workspace on a page, which means Blockly.getMainWorkspace() might return the wrong one.  It's better to keep the workspace is a variable when it is created, and use that variable.

But this is tangential to the XML stuff, which is all correct.

The file up- / down load is the tricky portion because of the browser security limitations. I'm using fileSaver.js (https://github.com/eligrey/FileSaver.js/)
