sir
I am using Office 365 Excel. But when I saved the file I saved it in 97-03 mode. But when opening the file again, this error appears. "the file format and extension of 'kumar.xls' don't match. the file could be corrupted or unsafe. unless you trust its source, don't open it. do you want to open it anyway?" Can you kindly advise us.
