> I'm extracting data from an Excel file using win32com.client. Everything works fine except for when the value "#N/A" is entered in excel. An empty cell. I assumed I do something as

> But that doesn't seem to work. When I debug the piece of code while handling #N/A in a cell the type of the cell according to win32com.client is int and the value in the cell is -2146826246. Chances are small just this number will appear in Excel, but it looks dirty to depend on that value to decide if a cell is empty. Looked around the net for a solution, but nothing came up so far.

Does that number happen to be -1 * sys.maxint?
