Hello, 

 When I am doing excel migrations with rows more than 3000 (ish), I get an error when validating or executing. 
 “The argument is invalid or missing or has an incorrect format”

When I select smaller amounts in chunks, everything validates/executes fine.
This is very inconvenient when there are 10000s of records. takes forever to do in chunks. 
has anyone encountered this issue? Any knows fixes?

Thank you,
Kalindu
