Hi Morten,

Thanks. Just the selected rows from the CSV are going to be stored in the
data store. But to do so, first I need to show the content of the CSV to
the user (graphically). So I have to read the content of the CSV first.

If I am going to do it in one of my own web app, what I will do is,

1. Upload the CSV to server temporary.(say tmp.csv) (I need a solution for
this step in the DHIS context)
2. Read back the uploaded CSV(tmp.csv) show it to the user. (draw a chart
in my case)
3. Allow the user to select the required data.
4. Save only the selected data(rows) to the database. (In DHIS, saving to
the data store)
5. Delete tmp.csv

So what I really need is to do the same thing in step 1 above using the
DHIS Web api.

Thanks.
