Microsoft Excel Error – “The file is corrupt and cannot be opened”

We all have used Microsoft Excel and no matter what field of business we work in, Excel is an absolute necessity. It is a part of the very successful Microsoft Office suite which gets regular updates every year. Of course, Microsoft never disappoints when it comes to new updates of Microsoft Office but there have often been small bugs reported when users updated from an older version to the newer one.

When Microsoft launches a new version of MS Excel in MS Office then also provides a strong solution for many errors through KBs. Sometimes it becomes very confusing to fix some errors then user follows hit and trial option to fix them.

With the new Microsoft Excel 2010 and above versions, it was reported that the application throws an error when an Excel file that was created by an older version of Microsoft Excel is opened.

After upgrading from Microsoft Excel 2007 to 2010, the application throws the following error when a file created in Excel 2007 or an older version is opened in the 2010 version.

“The file is corrupt and cannot be opened”

Now, the first reaction to this message is always panic. You always fear that all your important data has been corrupted and deleted. But, though Microsoft Excel states if your file is corrupted then it is not really lost and you can definitely try to recover it. The important thing here is to focus on recovering the corrupted Excel files back anyhow. Since we all know how much sensitive data is held by Excel files and one small corruption could result in a lot of data loss.

Ways to resolve the Microsoft Excel Error

There are quite a few ways to resolve this particular Microsoft Excel Error, these include both manual methods and using a third party tool.

Changing the Protected View Settings

When you upgrade to Microsoft Excel 2010, the Protected View settings are changed by default. Most of the time, this is the problem why Excel throws the error. This is what you need to do to change the settings back again-

  1. Go over to the File Menu and click on Options
  2. In the Options window, choose the last tab,Trusted Centre
  3. Now click on ‘Trusted Center Settings
  4. In the new window, choose ‘Protected View
  5. Unchecked all the options available and click OK

After this, close the entire application and open it again. Though this should fix your problem, if it doesn’t, hope over to our next solution.

Changing Component Services Settings

Next way to get around this error is by changing Component Security Setting and here is how you can do that-

  1. Go over to the Search tab in the Start menu and type ‘dcomcnfg
  2. A new Component Services window with a three pane view will open
  3. In the left-most pane, expand the Computers folder
  4. Now, right click on My Computer and choose Properties
  5. Choose the Default Properties tab on the new window
  6. Tick mark the option ‘Enable Distributed COM on this computer’, set the value of ‘Default Authentication Level’ as ‘Connect’ and ‘Default Impersonation Level’ as ‘Identify
  7. Click on OK and restart Microsoft Excel

If the error still isn’t resolved by any of these methods or if these methods got you more confused, then we strongly recommend going with the last option.While the manual methods are the first way to go, they aren’t as effective as the software available in the market.

Using a third party tool
Sometimes the problem is not just with the settings of Microsoft Excel, instead the file can be actually corrupted partly or completely. In these situations, you need a reliable third party tool which can recover everything from corrupt excel file.

These tools are safe and secure as compared to the online repairing of the excel files. When you try any excel file recovery tool then, always make a copy of your file before using them.

So now, you never have to worry about any of your Microsoft Excel file getting corrupted.
