  • Navigate to the folder containing the XLSX file you want to repair.
  • Right-click the file and select "Copy" and then right-click on a blank space within the folder and select "Paste." This action generates a backup copy of the corrupted file.
  • Open Microsoft Excel 2007 or later.
  • Click the "Office" button in the top left corner of the window and select "Open."
  • Navigate to the folder containing the copy of the XLSX file you generated previously and select it by single-clicking its icon.
  • Click the arrow located to the right of the "Open" button and select "Open and Repair."
  • Select "Repair." If you previously attempted this method and the process failed, try to extract only the values and formulas by selecting "Extract Data" instead. Regardless of the method you choose, your data will appear on the screen within a few seconds if the process completes successfully.

    How to recover Excel lost file

    How to solve some troubles with excel files you may learn from-

    How to Recover an Excel File for Free

    1.Check the Recycle Bin--if you've accidentally deleted the file, it should still be there unless you've emptied the bin, and you can click on the file and recover it.

    2.Use the Auto Recovery Pane when you open Excel. Review the document recovery pane. If Excel has managed to recover your file, it will show in a separate pane on the left-hand side. Identify your document in the pane, then click on it and choose "Open" to open the recovered file.

    3.Try manually repairing the file. Click on "File" in Excel 2003 or the "Office" button in
    Excel 2007, then select "Open" and click on the arrow next to the "Open" button. Click on
    "Open and Repair" and choose from two options: click on "Repair" if you want to try to completely recover the file, or click on "Extract Data" if you previously tried Step 1 and it did not work.

    4.Search for the file manually on your computer. When performing a system search (click "Start" and select "Search" in Windows XP and Windows 2000, or press the "Windows" button and "F" key in Windows 7 and Vista), make sure you choose "Advanced Search Options" and then check the "System and hidden files" check box. You may be able to find your missing or corrupted file using this search: double-click on the file name in the search results to open it.

    If nothing can help you, look at Excel Repair Toolbox

    As a solution, it costs money, but effective-

    How to open Book1.xls file.?

    To open an Excel spreadsheet, you need a program that understands the .xls format. You can get the free Excel Viewer from Microsoft: . This is the latest version and will work with computers running Windows XP through Win7. There is a Mac OSX version available but I'm not sure of the URL. If you have an older OS, you can try searching for an older version of the Viewer.

    Another option is to install any office suite that includes a spreadsheet program or just the spreadsheet program. Microsoft sells Office in several versions and you can buy Excel separately. There are several other spreadsheet and office suite software options that will also read Excel files. Open Office and LibreOffice are both free office suites which can read any Excel file. ( and ) Open Office and LibreOffice have versions that work under almost any OS.

    I hope this helps.

    A supplemental program that runs additional code. Excel add-ins use the Open XML file format to store data, and they support using VBA projects and Excel 4.0 macro sheets.

    either your MS Office Installation is currupt or your system in infected with a virus.
    Please scan your system using a good virus scanner. (Please uninstall any prior scanner if you have and pl avoid using McAfee for the time being).

    Now open your excel go to Office button
    Office Button --> Excel Options --> Resources --> Diagnose
    if problem comes during diagnosis, please connect your system to internet and if fails, please reinstall office again.

    My excel file was working yesterday, but as of

    Shouldn't be a date issue... did you open the file the way you normally do ?
    Something has changed here... bad shut down with this file opened... maybe.
    Open Excel and pull down the File Menu and see if there are more than copy or version of your spreadsheet. Look at all...
    File could have corrupted the Font or could be a Virus. Try just changing the font in one cell.
    If this is your only copy of the file... make a copy to see if it works on another machine... that will isolate the problem... it may just be corrupt... the fix is Excel healing it on it's own when it opens.
