Json will not generate with nested array

I am generating a nested array. The top nest has 1300 records, in the second nest there are 256. Essentially I have 1300 dates, with pricing for 256 equities for each date. I am trying to generate a data source with 3 years of pricing. When the top nest is reduced to about 200 it works - anything above that fails. Is there a hard limit of which I am unaware? I do have the top plan - so should be able to download this amount of data?

I thought it started working - but it does not. I have also changed the date from a formula to a sequential dataset to see if there were processing speed differences - but I still recieve no output.

Hi @thomas.zdon

According to this How can I force mockaroo to generate a file on the server instead of directly downloading it?, your file should be generating on the server.

I can’t test as on the free version. Look in top right corner and is icon with cloud and down arrow. Is it there?
