Hi my organization is very interested by seatable.
We need tu update ou data many times every month, but with seatable we can import csv in a table only when the user create a new table and not for adding or modifying data.
Am I wrong?
Many thanks
Sorry to say, but you are wrong.
There is an update option as you can see below:
Thank you very much for your help.
Regards
Pleasure! 
If you want to know more about importing/exporting data into SeaTable, have a look here: Datenimport und -export - SeaTable
Do it like thousands of other people who have used SeaTable to develop powerful processes and get their ideas and tasks done more efficiently.
