    Corrupted excel 2007 file assist

    Hello, I recently reinstalled win 7 and forgot to back up a few files from my old desktop beforehand, I have used a data recovery tool to get the files but when I try to access them it says they are corrupt, I have tried the few things I can think of like changing the file extensions to various things, open excel in safe mode, excel open and repair.

    Anyone have any suggestions or know of any programs to fix this? Could really do with getting into this file.

    Cheers.

    Try opening Excel, then open excel files through the excel application.

    When an Excel file is corrupted, then you can try several methods to recover it:

    1. First of all, you can try to repair the file manually in Excel, as follows:

    (1) On the File menu, click Open.
    (2) In the Open dialog box, select the file you want to open, and click the arrow next to the Open button.
    (3) Click Open and Repair, and then choose which method you want to use to recover your workbook.

    You may find more information about this at:

    http://office.microsoft.com/en-us/ex...001034656.aspx (for Excel 2003)
    http://office.microsoft.com/en-us/ex...017.aspx?CTT=1 (for Excel 2007)
    http://office.microsoft.com/en-us/ex...840.aspx?CTT=1 (for Excel 2010)
    http://office.microsoft.com/en-us/ex...554.aspx?CTT=1 (for Excel 2013)

    2. If method 1 fails, there are still several methods to recover your Excel file manually with Excel, including writing a small VBA macro, as below

    http://office.microsoft.com/en-us/ex...#_Toc337637262

    3. Third, there are also free tools from third-parties that can open and read Microsoft Excel files, for example,

    3.1 OpenOffice at http://www.openoffice.org. This is a very famous open source project that is designed to support Office file formats, including Excel files. The software can run under Windows.

    3.2 KingSoft Spreadsheets at http://www.kingsoftstore.com/office/free-excel. This is a free Windows tool that can open Excel files.

    3.3 Google Drive at https://drive.google.com/ also support to load Excel files.

    Sometimes when Excel fails to open your file, these tools may be able to open it successfully. If that is the case, then after the Excel file is opened, you can just save it as a new file which will be error-free.

    4. For xlsx files, they are actually a group of files compressed in Zip file format. Therefore, sometimes, if the corruption is only caused by the Zip file, then you can use Zip repair tools such as WinRAR at http://www.rarlab.com to repair the file, as follows:

    4.1 Assuming the corrupt Excel file is a.xlsx, then you need to rename it to a.zip
    4.2 Start WinRAR, go to "Tools > Repair Archive" to repair a.zip and generated a fixed file a_fixed.zip.
    4.3 Rename a_fixed.zip back to a_fixed.xlsx
    4.4 Using Excel to open a_fixed.xlsx.


    There may still be some warnings when opening the fixed file in Excel, just let ignore it and Excel will try to open and repair the fixed file. If the file can be opened successfully, then you can just save the contents into another error-free file.

    5. If all above methods do not work, then you may try third-party tools such as DataNumen Excel Repair at

    http://www.datanumen.com/excel-repair/recovery.htm

    I have used it to recover some Excel files successfully. It provides a free demo version so that you can try to see if the data you want can be recovered or not.

    Good luck!
