Maximum of columns for profiling

I have a spreadsheet with over 2000 columns where I am trying to profile several rows of data. What is the maximum number of columns that are supported for profiling?

Hi Jason,
have you already tried it? We haven't tested the maximum number of columns for profiling yet.

Ok, tested now. We have a limit of 1024 columns for Toad import. And with 1024 columns it works fine. I was testing on SQL Server with 10 rows generated for 1024 columns.
