Once it is enabled, this App adds Export choices in several places:
Backlogs view: stories
Features view: features
Release details: sprints and stories (one sheet for each sprint)
Sprint details: stories and tasks
For every export provided by this App, you can choose between the Excel spreadsheet format (.xls) or a comma-separated values (.csv) format. If you intend to use Excel, then the former is the best choice, while the latter is easy to parse so it is a good fit for ad hoc processing.
By default, CSV values are surrounded by double quotes and separated by commas, but this can be changed to any other character when exporting your data.
All exports are available through API calls. They are not documented yet so if you are interested in using them, please contact us and we will guide you.
