For most typical Word documents the extension is .docFor Excel workbooks (spreadsheets) the extension is .xlsIn general the file extension is the 3 letter/number "code" after the period in the complete file name that gives a hint as to what type of file it is. For example, in the file name resume.docthe word resume is the file's actual name and the .doc tells you that it is a document file.

Suppose you have to view an important excel sheet data but you have forget the password then you need to do excel password recovery, unfortunately MS excel doesn't offer any option for password recovery. You can try the following steps but it will work in MS excel 2007 only. 1) Change file extension .zip from .xls/xlsx. 2) Extract this zipped file. 3) Go to the extracted files and navigate to the .xml for the target sheet (found in the 'xl\worksheets' directory) like filename.xml 4) Open this .xml file in to xml editor and file and find <sheetProtection password="CC58" sheet="1"/> line and remove it. 5) Now save this file and change extension back to .xlsx from .zip. You will be able to open your file successfully without any password.
