FeatureRequest: export/copy format

[bussnet]

I'd love to have custom formats for copy and exporting data.

For example:

• CSV with different seperator
• XLSX (maybe just an option to add a bash command that recieve CSV or JSON and can reformat it)
• markdown
• just list of selected numbers with , separated to reuse in a query or other tool

I also will find it usefull to have this option also for copy, not just exporting. Especially the markdown, number list or json format, to just copy it in an Email or issueTracker or dirctly use this in another tool.
