Seems that when I copy/paste values into the data builder instead of using the import feature, it imports the first many records and then randomly show blank values for some.
Any idea why?
There are some limitations on how much data can be imported via the clipboard. At this time the limit is 10,000 cells.
Take the amount of column you have multiply by the number of rows. This must be less than 10,000.
Can you confirm if you have more or less than 10K cells?
Yes i had more than that amount. tested it with first 5000 records and it okay.
Marked your answer as solution. Thanks
