It would be very useful to be able to export SSRS Reports in a specific format (PDF, Word, Excel...) programmatically, both in JS and in C#.

Business cases: definitely a win factor to ease the life of Sales People.
- 1-clic download of documents through a customized button in the command bar.
- Programmatically add exports of SSRS Reports as an attachment to an email (for example: 1 clic to send a quote).
- etc.

Word and Excel Templates are not powerful enough to meet customization options offered by SSRS (dynamic content, conditions, expressions...)

It is only possible today through unsupported code.
