"Export data as" functionality #24
Description
Is your feature request related to a problem? Please describe.
Suppylement does not provide an easy method to export the data file into other formats. This can be done relatively easily using other programs, or a custom script. It goes in line with the program's idea to be able to export the data easily. Having easy access to data in other formats will increase the usefulness of Suppylement by allowing easier integration with other software, or more comfortable browsing of the data.
Describe the solution you'd like
An export mode added to Suppylement. This mode will accept at least a format argument, specifying the output format. These can theoretically include any format supported by Pandas but we are most interested in HTML, XML, Excel and JSON at the moment.
Other potential arguments passed to export mode may include the standard selectors, specifiers and filters offered in Application.display. I'm sure there is a way to implement this in such a way that we can share the selection logic with Application.display without having to duplicate it.
Describe alternatives you've considered
No alternatives considered other than manual conversion.
Additional context
This feature is targeted for a future release of Suppylement. Not being core or critical functionality, we can push this back to be worked on someday. Likely once the core is more solidified, or we are closer to a beta development status.
