someone sends me an excel file which is exported from quickbook.
file size: 3.6MB (if i re-save the excel, the file size is very small)
file type: ms excel 97-2003 worksheet
sheet1: 252 rows and 4 columns only
other sheets: empty
no. of sheets contained: 4
"QuickBooks Export Tips", Sheet1, Sheet2, Sheet3
when my program opens this excel file, the program freezes. cpu surges to 100%
