At times, while opening a workbook in Excel application (especially in MS Excel 2002) it may happen that you receive the following error message:
'Unable to read file.'
The above problem may occur if the different portions of the file structure get corrupt or damaged.
As the first instance of damage is encountered, open the Excel sheet in safe mode. It tries to repair the file. After repair, it checks for corruption left in the document, if any, and then makes an attempt to itself restart in a minimal-load mode. If the complete repair fails, Excel fails to restart and throws an error message.
The usual way to deal with such problems is to install the latest service pack for Microsoft Office XP. The other way to resolve this issue is to install a supported Hotfix offered by Microsoft.
