Hello thunkers
‘create new row’ adds one row to a Data Source. That work’s fine. However, to upload multiple data rows from an API into the data source I use a loop containing the ‘create new row’ block.
Much to my surprise only one row gets created. Irregardless, how many times the loop runs.
Is there a work-around?

Many people are expressing problems with the create row block,
I encountered these problems in my experience, in this particular case linked below, I was able to “fix it”, give it a try ⬇

> That’s just cause I decided to change the original picture with a more fitting one created on purpose, it’s not that the problem, picture is wrong,and those blocks work if I use the OLD localDB commands. I think I just found the cause and I hope you can do something about it: Data sources IS SLOW. It might be due to the fact that it pulls every row from the airtable db, I just ‘solved’ one problem I was having, but I can’t wait 1 second for every row of the database, I’m going to add pictures…
Also, @domhnallohanlon @Domhnall, you problably will want to group all the different posts on the create row topic, included mine I just linked.
Thx

Is it working with date input or something like that i mean without loop?

I don’t think the Create Row block can run in a loop that quickly. I think you might need some delay or you might have to nest the Create Row blocks inside the “do” section (note that this will currently **not** work because of a known bug. See [Create row block not working well from yesterday](http://community.thunkable.com/t/create-row-block-not-working-well-from-yesterday/887050). Also see the link @maxb posted above.
