New Post: Remove formatting from file

I'm using the AsDataSet() method to import large Excel files into DataSets. It performs extremely well until I hit a file that has a lot of formatting. With formatting, I cancelled after ~ 30 minutes. I then opened the Excel file, removed all formatting, and it worked almost instantly.

I'm using .xls files, not .xlsx.

I might have the option of removing the formatting when they are generated, but it would be a lot easier for me if I could somehow make then work, whether it's by telling ExcelDataReader to ignore the formatting or by somehow removing it before processing.

Any ideas?
