Reasons for Occurrence of The Error in Excel 2010

The ‘The File Is Corrupt & Cannot Be Opened’ error in Excel 2010 can be attributed to various causes. Understanding the specific reason behind this error is crucial, as it not only aids in finding the right solution but also empowers you to adopt improved practices to prevent such errors in the future. Let’s explore these causes in detail:

  • An Unexpected Equipment Damage or An Unexpected Power Failure
    An unexpected and sudden power failure can lead to the forced closure of all files that were open just before the shutdown. Consequently, the Excel file becomes unavailable, potentially causing the ‘The File Is Corrupt & Cannot Be Opened’ error.
  • Mishandling Excel Files
    Mishandling files always poses a risk. Accidental deletions, formatting of drives or folders, and inattentively closing a running Excel document without saving it can all lead to data loss. Such actions may ultimately trigger the ‘The File Is Corrupt & Cannot Be Opened’ error.
  • Defect in The Excel Application
    When an application or program becomes unresponsive during your work, necessitating its closure, you risk losing unsaved data and potentially causing errors. Another scenario is encountered with newer Excel versions, where files upgraded in these versions may become inaccessible or uneditable in many cases. Engaging with unfamiliar new features without proper understanding can further jeopardize your files
  • Hardware Issues
    Hardware failures also stand as a common factor contributing to the corruption error. This includes hardware components such as CD/DVD drives, USB flash drives, removable hard disks, and more. Issues like damaged heat assemblies and connector problems are quite prevalent in this context. While these problems can often be resolved, repairing Excel files becomes more challenging in the event of a storage media breakdown.
  • Bad Sector
    Usually, after an extended use, your hard drives might develop bad sectors in it. Other causes of bad sectors are improper shut downs resulting in the data that falls in bad sectors to become inaccessible.
  • Large Size of Excel Files
    MS Excel, being a spreadsheet software, isn’t designed as a database with extensive data storage capabilities. Consequently, it may close automatically when faced with the challenge of handling a large quantity of data. As the size of an Excel file increases, the likelihood of file corruption also rises.
  • Hacking or Virus Attack
    Virus attack and hacking causes a significant amount of damage to your Excel files. The data might disappear and you might lose them. Since much of your information stored in these files can be misused by the hackers. In case of a viral infection, these files cannot be opened and hence becomes inaccessible.
  • Natural Calamities
    In addition to the previously mentioned factors, several other elements can potentially damage your Excel files, making them inaccessible. Natural disasters like tsunamis, earthquakes, floods, and others are unpredictable events that can directly or indirectly harm Excel files by affecting your system and infrastructure.
