Uploading data - append data table

I am uploading a CSV file and I would like to append a table in backendless. How do I create custom object IDs for each new entry and upload that data to backendless?

I tried doing it but it only uploaded the first row or data but not the additional 50 rows.

Hi Nevin!

For creation valid import file you can use this doc https://backendless.com/documentation/manage/mgmt_import.htm

For example you created csv file with following structure:

"objectId(STRING_ID)","updated(DATETIME)","ownerId(STRING)","name(STRING)","created(DATETIME)"
"your_custom_object_id",null,null," ","10/27/2015 00:00:00 GMT+0000"

In “your_custom_object_id” you can set your custom object id.
