How do i upload data offline after deploying a form?

I dont think that kobo will accept your data as CSV.
Kobo has API, if you want to talk with it apart from GUI you should talk with it through API.

there is already a tool called java based Briefcase. you can use it to pull and push data through kobo. It can event export CSV. tBUT o push data, you must have your data in XML.

to summarize, there is no easy way to push CSV or other offline data in an easy way.
these are all what I know.

@solujimi, please explain what you want to achieve. Kobotool work in online and offline mode and once data collection is completed (finalized), you can click the send finalized form to upload it to the server. But we need to understand what you are trying to do in order to provide that support.
